How To Make Your Home Fallout Proof
A nuclear attack or disaster will come without warning, and while it is not practical to harden your home against the shockwave and thermal blast of an atomic bomb, you can take steps to shield yourself and your family from the impending fallout.
A purpose-built fallout shelter is ideal but also prohibitively expensive and outside the reach of most of us. The good news is that we can take steps to secure our homes against fallout without digging a bunker in our backyard.
What Is Fallout?
Nuclear fallout is caused by the vaporized debris mixing with the radioactive particles that make up a mushroom cloud. The wind then carries this fallout downwind from the blast.

Fortunately, most of the fallout in the immediate area will fall within twenty-four hours and look like ash or sand.

Surviving in the Aftermath of a Nuclear War
By Bill White
Here in the prepping community, we’re accustomed to talking about EMP as a TEOTWAWKI event, perhaps even our “favorite” such event, at least from the viewpoint of planning for it. But somewhere along the way, we’ve managed to lose track of the fact that conventional nuclear war is still a very real possibility. Our “friend” (cough, cough) Vladimir Putin has reminded us that such a possibility is quite real.
Granted, if Russia let loose a full-blown nuclear attack against the United States, there would probably be at least a few missiles fused for a high-altitude burst, generating an EMP. But that’s an assumption on my part. What if there weren’t any fuses like that, or what if those fuses didn’t work right? We’d be looking at a conventional nuclear war without the EMP taking out the grid.

Preparing for Biological Warfare
History repeats. Biological warfare has been used in the past; it will be used again. Bodies of plague victims were catapulted over the walls of besieged cities as late as the eighteenth century in Europe.

Survival Scenario – Can You Survive a Nuclear War?
Original Article
So here we go…
By September, 2016 the North Koreans have quietly built up an arsenal of nuclear weapons and distributed them around their country in various secret locations. The U.S. and other NATO countries are aware of some of the activity, but badly underestimate the size and number of weapons, and the determination of the North Korean leadership.
A border flare-up with South Korea starts with conventional shelling and then quickly escalates to small tactical nukes along the border. A few small towns and several important bridges are eradicated before the rest of the world can react. The U.S. reacts by sending stealth bombers into North Korea to bomb Pyongyang, but North Korean leadership has long since moved into mountain bunkers with all their command and control.
The North Koreans react to the bombing of Pyongyang by dropping a 20 megaton bomb on Seoul, the capital of South Korea. The U.S. responds with three MIRV’s, again targeting Pyongyang and several port cities as well.
China, upset at the nuclear testing by their neighbor in earlier years, had pretty much written them off as allies. When Chinese leadership saw the war escalating they too opened fire on North Korea with nuclear weapons.
North Korea finally opens the floodgates and shoots sixty-five of their weapons at the United States, a full two-thirds of their arsenal was saved just for us.
Russia inexplicably joins with North Korea and shoots at the US and China.
The world has now been officially at war for less than four hours.
In the United States warning sirens go off across the country and people head for shelter, confused and scared, hoping that it’s just a drill.
The first missiles from North Korea come across the North Pole and hit Washington State and California. Shortly thereafter a rain of missiles comes down across the Midwest. Russia’s weapons target the east coast and everything from Boston to Florida is pummeled by MIRV’s and nuclear bombs ranging up to 50 MT.
It doesn’t matter where you are, the world war that lasted less than 24 hours has affected you. Fires rage out of control, nuclear fallout is in the air, EMP has destroyed a lot of the delicate electronics our world runs on, and most of the large cities have become blast zones.
You have managed to survive the initial war somehow, but now you emerge from your shelter into a world vastly changed. Although there’s some structural damage to your home/apartment building/shelter, it appears solid enough to live in.
The government is setting up emergency shelters where they can, but are quickly overwhelmed by the number of survivors needing medical attention, shelter, food and clean water.
Look at your own situation – current level of preps, location (close to a big city or living in the hills?), number of people you have to care for, etc.
This is it folks. TEOTWAWKI. What do you do? Stay in place? Head to one of the FEMA camps for help? Start robbing people as they go by because you haven’t prepped? Build a wall around your place against the people pouring out of the cities? Open your doors and start helping those who need aid? It doesn’t look like there’s going to be much help in the foreseeable future.
-Jarhead Survivor
BTW:
Update: Yeah, the rocket fizzled and I know that they’re nowhere near to being a nuclear super power. It’s just a thought exercise, folks! A little something to get the thought processes going. Have fun with it!

Protecting Yourself from Radiation
Original Article
To begin with, you probably want to know how close you are to a nuclear reactor. Beyond that, you want to look at the typical wind patterns and see how likely you are to be “downwind” in the case of a release of radiation. These things may impact how much money and time you allocate to preparing for this particular disaster scenario.
Steps to Take to Safeguard Yourself Before the Emergency
Consider storing and doing the following:1. Potassium Iodate
If you want to prepare for the possibility of radiation, I would begin by buying some KIO3 tablets. It acts to “fill” your thyroid with safe iodine so that it will not absorb radioactive iodine in fallout. One of the major problems radiation victims suffer long-term is thyroid cancer. KIO3 a preventative. You have to take it before radiation reaches you or as soon as possible. It does not rid your thyroid of radioactive iodine after the fact. In other words, by the time you know you need it, it’s too late to order. Many in Japan sadly found that out.
Iodine-131 actually “decomposes” relatively quickly (within weeks or months). The danger from this particular radioactive particle is shorter lived than others.
2. Vitamin D and Vitamin K
These help rid your body of irregular cells- in other words, cells that may be affected by radiation and therefore replicating or acting improperly may be killed off better (appropriate apoptosis) in the presence of these two vitamins. Vitamin D also helps the body with DNA repair.
3. Potassium and Iron
These minerals may help in combating some of the radioactive particles that stick around longer. Cesium-137 has a “half-life” of 30 years. This is still commonly found in the ground around the old Chernobyl reactor in the Ukraine. It is easily taken up by the body because it mixes well into liquids. It is also carried easily by the wind.
4. Other Antioxidants and Herbal Supplements
There isn’t a “magic bullet” for countering radiation, but some things are known to be helpful in protecting the body from the effects of radiation. Some of these include turmeric, gingko biloba, garlic, ginger,ginseng, melatonin, magnesium, and spirulina.
5. Choose a centrally located room in your home. It should be the one with the fewest windows, preferably a basement or storm shelter. Store supplies you may need there (the usual- food, water, medicine, clothes, flashlights…). Consider what you will do for pets or livestock.
6. Make sure all your loved ones know that this is where the family will gather in case of radiation.
What to Do at the Beginning of the Emergency
1. Remove all articles of clothing before entering your sheltered area if you have had any contamination risk. Doing so could remove up to 90% of the radiation and you do not want to bring it inside.2. Wash as thoroughly as you can to get rid of what is on the surface of your body.
3. Close off all vents and stop drafts that may bring contaminated air into your shelter. If possible, seal off doors and windows with plastic sheeting and tape for the period of time that a radiation plume may be passing over. You can only stay sealed up without fresh air for a few hours though.
4. Keep your emergency radio on to find out updates. Hopefully, you will be able to track the direction of the radiation, find out about medical help, etc.
What to Do Afterward
In the days after radiation has been released, there are a few other things you may want to do to help protect yourself. Of course, stay inside as much as possible until you are sure it is relatively “safe” to venture out.1. Eat whole grains and the foods high in the above mentioned nutrients. High fiber foods with phosphorus spend less time in the digestive tract and therefore help the body in eliminating all wastes. Also, being a plant and therefore low on the food chain, any toxins the whole grains may have been exposed to will be less concentrated than those found higher on the food chain.
2. Avoid some foods- highly processed, very fatty, and sugary things contain less nutrition anyway and are held in the GI tract longer.
3. See a doctor as soon as possible if you suspect radiation exposure. He may prescribe Prussian Blue, DTPA, or Neupona.
In the final piece in this series, I will outline the symptoms radiation sickness, technically called Acute Radiation Syndrome.
Do you have anything to add? Have you taken any classes or found any good books with information you’d like to share? Please do so in the comments section.

What’s Your Annual Radiation Dose?
Original Article
Because radiation is an everyday part of our lives, we cannot avoid it. Our home appliances emit small amounts of radiation, as do our cellular phones. Even though we may not like the idea of being exposed to radiation; we can, however, reduce our risks by controlling, to some extent, our exposure to it. This calculator can assist you in finding out how much radiation you receive on a yearly basis from natural means and from un-natural means.
Annual Radiation Calculator
Natural Ways to Reduce Radiation in The Body
According to the website, survival-spot, the author provides natural alternatives to assisting the body in ridding itself of radiation exposure rather than ingesting potassium-iodide. Foods such as kelp, rosemary, spirulina, miso soup and niacin all assist the body in fighting radiation damage. Making these foods a regular part of your diet, could help lower your chances of radiation damage to the body.
Other foods that may help in combating radiation sickness are foods that naturally detoxify the body. Foods such as reishi mushrooms, green and black teas, garlic, nettles, dandelions, ginseng, lentils, collards and mustard greens.
Educate Yourself
Everyone is so concerned about radiation levels increasing due to the disaster in Japan. Ironically, we absorb radiation everyday. Knowing the proper levels of radiation we are exposed to each year can help us stay healthier. Those that are concerned about limiting their exposure to radiation can eat foods that have detoxifying properties, as well as staying away or limiting exposure of appliances and machines that radiate radiation.

Geiger Counter Numbers, How Bad is Bad?
Original Article
Given the recent events in Japan and the nuclear reactor damage and radiation entering the atmosphere there, the following information may help to understand the units of measurement being discussed, and how it may correlate to Geiger Counter readings such as those being displayed around the country on the Radiation Network.
Units of Measurement (Radiation)
1 rad = 0.01 gray (Gy)1 rem = 0.01 sievert (Sv)
1 gray (Gy) = 100 rad
1 sievert (Sv) = 100 rem
Rad and Gray are ‘absorbed dose’ units.
Rem and Sievert are ‘equivalent dose’ units.
Why a Rem and a Sievert?
They relate to biological damage done to human tissue and factor the differences between types of radiation. A multiplication factor is used that represents the ‘effective’ biological damage of a given type of radiation. This is the main reason for these units – to factor the differences in damage that is caused from one type of radiation to the next.Radiation Factor (QF Quality Factor)
(1) Beta
(1) Gamma
(1) X-ray
(10) Nuetron
(20) Alpha
For example, the list above shows that a ‘rad’ or ‘gray’ unit of ‘Alpha’ energy that is absorbed by soft human tissue does 20 times more damage than a ‘rad’ or ‘gray’ of Gamma, X-ray or Beta radiation.
Measuring Radiation with a Geiger Counter CPM
What is CPM (also the ‘number’ used on the Radiation Network )?
CPM (counts per minute) is a measure of radioactivity, a unit of measurement for a Geiger counter. Technically, “It is the number of atoms in a given quantity of radioactive material that are detected to have decayed in one minute.”Most Geiger counters are calibrated to Cs137 (Cesium).
1,200 CPM on the meter (for Cs137) is about 1 mR/hr (milliRad per hour).
120 CPM on the meter (for Cs137) is about 1 uSv/hr (microSievert per hour).
How many CPM of radiation is bad?
Answer: It depends on how long you are exposed at any given level. The Radiation Network website, for example, uses a threshold warning level of 100 CPM, mainly because it is unusual to observe levels of 100 or higher without something more going on in the area than just background level.Having said that, how could one figure out the ‘badness’ of a given level? How bad is bad? All we need to do is put in terms that makes sense.
First, we must understand a few radiation facts and numbers regarding dosage. There tend to be lots of conversions and it can be confusing, but by plodding through the math, you can determine a better idea and relationship of the Geiger counter numbers versus the risks to your health.
Radiation Dosage
Radiation dosage is a measure of the risk of biological harm that the tissues receive in the body.The unit of absorbed radiation dose is the sievert (Sv). Since one sievert is a large quantity, radiation doses normally encountered are expressed in milliSievert (mSv) or microSievert (µSv) which are one-thousandth or one millionth of a sievert. For example, one chest X-ray will give about 0.2 mSv of radiation dose.
On average, our annual radiation exposure due to all natural sources is about 300 milliRem, which is equivalent to 3 milliSieverts (3 mSv). Adding man-made sources (medical procedures, and others) the average annual U.S. radiation dose is about 600 milliRem, which is equivalent to 6 milliSieverts (6 mSv).
Average annual human exposure to radiation (U.S.)
600 milliRem (mRem)
6 milliSievert (mSv)
Radiation dose for increase cancer risk of 1 in a 1,000
1,250 milliRem (mRem)
12.5 milliSievert (mSv)
Earliest onset of radiation sickness
75,000 milliRem (mRem)
750 milliSievert (mSv)
Onset of radiation poisoning
300,000 milliRem (mRem)
3,000 milliSievert (mSv)
Expected 50% death from radiation
400,000 milliRem (mRem)
4,000 milliSievert (mSv)
What do the Radiation Network CPM numbers mean with regards to health risk?
With the examples of radiation dose listed above, we can correlate how long it would take to experience those effects based on a hypothetical Geiger counter CPM number.So, let’s use the number 100, since this is the threshold that the Radiation Network website has chosen. The Cs137 calibration factor listed above (120 CPM) was converted to obtain the proper factored results listed below (0.83x). Higher CPM numbers are also listed for relevancy.
Days compared with the avg. annual human exposure (U.S.)
207 (at 100 CPM)
42 (at 500 CPM)
14 (at 1,500 CPM)
2 (at 10,000 CPM)
Days to receive dose for increase cancer risk of 1 in a 1,000
432 (at 100 CPM)
86 (at 500 CPM)
28 (at 1,500 CPM)
4 (at 10,000 CPM)
Days for earliest onset of radiation sickness
25,937 (at 100 CPM)
5,187 (at 500 CPM)
1,729 (at 1,500 CPM)
259 (at 10,000 CPM)
Conclusion: Regarding the radioactive fallout from Japan reaching here to the U.S., the metered Geiger Counter CPM that we see on the Radiation Network can be compared to the equivalent ‘what-IF’ scenarios listed above. Not saying though that anything less would not be ‘bad’ for us, there are lots of theories out there regarding long-term effects of various types of radioactive ionized particles making it into the food chain, etc…
Interesting fact:
All food sources combined, expose a person to around 40 millirems per year on average.
Many foods are naturally radioactive, and bananas are particularly so, due to the radioactive potassium-40 they contain. The equivalent dose for 365 bananas (one per day for a year) is 3.6 millirems (36 μSv).
Other foods that have above-average levels are potatoes, kidney beans, nuts (especially brazil nuts), and sunflower seeds.
Ways to limit radiation exposure:
1. Time (limit exposure time)
2. Distance (intensity decreases sharply according to the inverse-square-law)
3. Shielding
(alpha: nearly anything… a sheet of paper will stop it)
(beta: wood, water, plastic-acrylic, aluminum)
(gamma: water, concrete, lead)
Disclaimer: Do not rely upon this information for life or health, it is only one person’s estimation based on a several hours research and punching calculator buttons. We have no affiliation with the Radiation Network, who may or may not agree with these numbers.

Potassium Iodide (KI) and How to Protect Yourself From Radiation Poisoning
Original Article
Potassium Iodide or KI is a salt of iodine and is what the body uses to make thyroid hormones. If you are exposed to radioactive iodine through fallout , your thyroid will quickly absorb it into your thyroid and cause serious problems. By super loading your thyroid with safe iodine via Potassium Iodide you can minimize your bodies absorption of radioactive iodine. It should be noted that Potassium Iodide is NOT a cure for radiation sickness nor will it prevent other problems that will occur from fallout or radioactive exposure.
Potassium Iodide should be taken when exposure to radioactive iodine is imminent. Local Government and Health Officials will notify the public if this precaution becomes necessary.
Taking Potassium Iodide does not provide 100% protection against radioactive iodine. Factors include how soon prior to being exposed that Potassium Iodide was ingested, how fast it can absorb into your blood and the total amount of radioactive iodine the person is exposed to. In other words, it’s critical to take as soon as notification is issued, that you take it in a liquid form and that you take the proper dose. And, of course, that you limit your exposure to any kind of fallout as much as possible.
There are two typical forms of Potassium Iodide, liquid and tablet. The liquid form typically comes as a crystalline powder that you mix with water. Tablets come in 130 and 65 mg, the 130 mg are typically scored for easy cutting. The dosages are as follows:
- Adults – 130 mg
- Breastfeeding Women – 130 mg
- Children 3-18 – 65 mg
- Children over 150 lbs – 130 mg
- Infants & Children 0-3 yrs – 32 mg
- Newborn – 16mg
These doses of Potassium Iodide
Potassium Iodide may be harmful to you if you are allergic to iodine or with certain skin disorders. There is minimal risk to taking Potassium Iodide unless it is taken for several days, you take more than the recommended dosage or you have a pre-existing thyroid disease.
Summing it up:
In my opinion, the easiest way to figure out how much Potassium Iodide to store is to calculate the maximum adult dosage (not the lower children’s dosage) for each member of your family and multiply it by 7 (1 week). This is designed to give you an excess to allow for spillage, etc. So, for my family of 10, I calculate 130 mg X 7 X 10 = 9100 mg or 9.1 grams. I purchase Potassium Iodide in 40 gram bottles (typically for $10 – $15) and have enough for pretty much my whole neighborhood.

Fallout: Natural Sources Of Iodine
Original Article
I suppose, in a sense, he was correct.
There's been much in the news about having to deal with potential radioactive fallout from the Fukushima powerplant's possible meltdown. Unit One and Unit Three have already been rocked by explosions and the threat to the remaining reactors is growing. Some news articles contend that a meltdown is in progress, or a partial meltdown has already occurred.
If a meltdown does, or has, happened fallout in the form of heavy and light particles will rise into the atmosphere and travel across the Pacific Ocean on air currents.
Maps tracking fallout patterns to the west coast of North America as well as an excellent article can be found here at Modern Survival Blog. It has updates on the developing situation and pertinent information regarding personal preparation.
The good news is many of the heavier particles will drop out of the airstream over the Pacific and probably not make landfall in North America.
The bad news is the more fine, lighter particles, will travel farther before dropping out of the airstream. These will make landfall, possibly as far as Colorado, before dropping out.
The good news is that if the quantity of fallout is small, it will be so widely scattered as to essentially disappear into normally present background radiation sources.
And there's where the hitch is.
How much fallout North America will have to deal with is also a question that is, pardon the pun, up in the air. If we use Chernobyl as a representation of a possible scenario, an estimated 50 TONS (100,000 pounds) of nuclear fuel "evaporated" in the explosion and fire. Much of it landed in the area immediately surrounding the plant, and even more in the areas downwind in the Ukraine. But significant materials remained in the air so that it traveled and triggered radiation detectors in Western Europe, and even the Eastern US.
Remember, Chernobyl was a single reactor. Japan is dealing with the potential for multiple reactor failures.
What most people should be concerned with are Cesium 137, Strontium 90, and Iodine 131.
Cesium 137 is released by reactor accidents and presents a significant health risk in that it distributes itself through the soft tissues and is a strong source of ionizing radiation. Ionizing radiation can destroy your DNA and disrupt the body's cellular functions. Half life is 30 years, and the primary path into the body is ingestion and inhalation.
Strontium 90 is not likely to be released by a reactor accident, BUT it can be. Strontium 90 mimics calcium and is readily taken up by the body. Half life is approximately 30 years and the primary path into the body is ingestion and inhalation.
Iodine 131 is readily absorbed by the thyroid gland as it mimics the non-radioactive form of iodine which is needed for the production of certain hormones. Half life is 8 DAYS, not years, so that is a sort of a blessing. Primary path into the body is ingestion.
Three simple steps to protect yourself from ingesting these elements:
Wash all produce thoroughly with clean running water.
Wash all cans of food prior to opening them to avoid potential contamination from radioactive dust that may have settled on the cans. (Remember your pets, too!)
Avoid drinking from open water sources (streams, ponds, etc.).
Much has been said about purchasing Potassium Iodine (Iodate)
If you find yourself unable to locate iodine supplements
Kelp
Arame
Wakame
Laver (Nori in Japan. It's that greenish/black paper-like wrap around makizushi )
Seafood (fish and shellfish)
Yogurt
Cow's Milk
Eggs
Mozzarella Cheese
Another strategy is eating peanuts, soybeans (and related like Tofu), canola oil, cassava, strawberries, pine nuts, millet, pears, peaches, spinach, bamboo shoots, sweet potatoes, and anything in the Brassica family. These are known to inhibit the absorption of iodine by the thyroid.
This last suggestion is a stop gap measure only to be considered if you do not have access to a source of iodine

The Reality of Bio-Terror
Thursday, June 10, 2010
Dirty Bombs

An analysis on Stratfor.com downplays the danger of Dirty Bombs. These types of bombs use common explosives to spread radioactive materials (hence ‘dirty’). There is no nuclear reaction, no mushroom cloud, just a normal explosion that coats an area with radioactive dust. Since they are much easier to build than an atom bomb, and radioactive byproducts are easier to acquire, there reasonable concern that terrorists will someday use dirty bombs.
The common media portrayal of dirty bombs is that they will “immediately cause hundreds or even thousands of deaths.” Not true, says Stratfor. A dirty bomb is not a “weapon of mass destruction” but rather a weapon of mass “disruption”. Immediate deaths would result from the explosion itself and the resulting panic when the bomb is found to be “dirty”. The dirty effects of the radioactivity are longer term and most people will be safely decontaminated (eventually).
The real problem is economic and psychological. Since anyone living or working in a radioactive area will sicken and die over days/weeks/years, the area must be cordoned off and abandoned until cleaned. A total cleanup will require relocating everyone, tearing down the buildings, streets, sidewalks, and scraping the soil. Not at all cheap if the area is downtown NY, London or DC. And not nice if the target is something historical and irreplaceable.
To back up their analysis downplaying the danger, Stratfor looks at the 1986 Chernobyl nuclear disaster in northern Ukraine. This was bigger than any possible dirty bomb and in fact more than one hundred times the radiation of the atomic bomb dropped on Hiroshima, Japan. The Chernobyl explosion killed 31 persons in the immediate aftermath. Over several decades it may contribute to the deaths of 9,000 people from radiation poisoning. But many of those affected by the radiation are still alive more than 20 years after the accident. Today, 5.5 million people live in the contaminated zone.
Fortunately for civilization, it’s not easy to use radiation as a mass weapon. Yes, a concentrated radioactive substance can kill individuals quickly with direct exposure – but such items are rare and quantities small. With dirty bombs the radiation is spread far and wide by the explosion; maximizing the number of people impacted but weakening the lethality.
Bottom Line
What should you do if you are a victim of a dirty bomb?
- Don’t panic!
- The CDC recommends sheltering inside a building with intact walls. If you’re outside, cover your mouth and nose to avoid breathing in the radioactive dust (VERY IMPORTANT), avoid touching anything, and get inside the nearest walled shelter quickly. While outside, clothing is an effective shield against energetic alpha particles but if you breath those same particles in – damage will be done.
- If inside a damaged building, move to an undamaged interior room.
- When you come in from outside, remove your shoes and outer clothing at the door. Up to 90% of the radioactive dust on you is on your clothes. Don’t spread it around your shelter. If possible seal your clothes, shoes, and breathing cloth/mask it in a plastic bag or other disposable storage. You don’t want to be near these clothes afterwards (or ever again).
- Shut all windows, outside doors, and fireplace dampers. Turn off fans and heating and air-conditioning systems that bring in air from the outside. It is not necessary to put duct tape or plastic around doors or windows.
- If outside or exposed, shower or wash ALL exposed skin with soap and water to remove any remaining dust. Be sure to wash your hair. Don’t put contaminated clothes back on. Don’t forget that your washing area may now be slightly radioactive from the rinsed off dust. Initially the washing water should be safe – water inside pipes at the time of the explosion is protected. But over time as water is used, you’ll be drawing from lakes and reservoirs that may have been exposed.
- Cover any open wounds to keep radioactive dust out of your blood stream.
- If you’re at home and have pets outside, get them indoors and wash them completely.
- Tune to the local radio or television news for more instructions.
- Don’t go outside until instructed to by authorities. When leaving your temporary shelter, cover up 100% with clean clothes/coat/blanket. You’ll need new shoes or a substitute. You’ll repeat the process of disposing the outer clothing layers and washing when you return to a shelter.
- Do not attempt to rescue your children at their school. They should be safe in a school shelter. You endanger yourself by traveling and contaminate the school shelter by demanding entrance or even opening the door.
- Don’t eat or drink from anything that was open and possibly contaminated by dust. Sealed food is ok but be sure to wash the outside container first. Avoid drinking public faucet water until authorities say it is safe. You don’t want to allow anything radioactive inside your body.
- If all goes well, your exposure will be no worse than an intensive medical X-ray and there will be no symptoms. However if you experience nausea, vomiting, diarrhea, and swelling and redness of the skin then you were exposed to a higher level of radiation and need medical attention ASAP.

How Much Radiation Can You Take
The first thing you have to understand about radiation is you can’t see it, smell it or taste it. The only time it will be visible is the fallout after a nuclear blast. This dust will have the appearance of dusty snow. Apart from that you won’t have any idea your in a radioactive zone without proper detection equipment.
So just how much radiation can the human body withstand? Here is a list giving you a basic idea of what to expect at what levels. All measurements here are calculated in RADS which is short for radiation absorbed dose.
5 RADS and under - No visible symptoms
5 to 50 RADS - Temporarily decreased red blood cell count (you’ll survive but will fee pretty ill)
50 to 100 RADS - Decreased production of immunity cells, you will be susceptible to infections, nausea, headache, and vomiting are common. With treatment you will survive.
150 to 300 RADS - Up to 35 percent of those who are exposed to radiation up to this level will die within 30 days. They will suffer nausea, vomiting and will lose all their hair
300 to 400 RADS - At this point your chances drop to 50/50 fatality rate after 30 days. Like the last level all the same symptoms will happen but with the addition of uncontrollable bleeding in the mouth, under the skin, and the kidneys
400 to 600 RADS - You have a 60 percent fatality rate after 30 days, symptoms like those at the 150 to 300 level starts to become visible in a couple hours after exposure
600 to 1000 RADS - Almost 100 percent fatality rate after 14 days. Your intestinal tissue will be severely damaged and almost all bone marrow will be destroyed
1200 to 2000 RADS - 100 percent fatality with immediate symptoms after exposure
2000 RADS and over - Symptoms set in instantly upon contact then will cease for several days, giving the victim a “false hope” that they are recovering. Suddenly gastrointestinal cells are destroyed and death will begin with delirium since the brain can’t function normally and starts to shut down.
If your interested in learning more about radiation poisoning I found this documentary on YouTube made by the BBC about the Chernobyl disaster and the following cover up the Soviet government used to try to try and down play the disaster.

Gas masks and protective clothing
Some people run to the local Army-Navy surplus store and buy a mask secure in the knowledge that they will be safe in the event of an attack.
Looking at the movies you get the impression that there's nothing more to gas masks
Having many years experience with Chemical & Biological weapons, I'll attempt to lay aside the myth of the gas mask
Do you need a gas mask?
This is the million dollar question. Most experts would advise that stocking up on gas masks
A gas mask will be effective IF you're wearing it before exposure to the agent or immediately upon exposure. If you're inexperienced in the use of gas masks, or if you take to long to find it, you may be putting your life more in danger than if you simply moved quickly to escape the cloud. Of course there's every chance that you will not know what kind of poison is in the air and may not have the appropriate filter in your mask. This may lead to a false sense of security.
In the case of a biological attack masks are of little use. In most cases a biological attack will go undetected for at least several days making the gas mask
It's also worth bearing in mind that gas masks are quite expensive. You can expect to spend about $200 for an effective mask. Then you need to decide if (1 you're going to carry the mask with you everywhere you go which would be uncomfortable, impractical and probably not too popular an idea with the kids or (2 you're going to have one mask for home, one for work, one for the car, and so on which would be very expensive.
NOTE
In the case of a biological attack, breathing through a doubled-up t-shirt will greatly increase your chances of survival in an emergency situation. Unfortunately, this method isn't effective against most chemical agents.
I would suggest that a gas mask
Gas mask filters have a limited life-span. Most of them have just a few hours of active use (depending on the amount of dangerous substance being filtered and the relative air humidity). At this point the filter needs to be changed. Never buy a second-hand mask as you will not know how much life the filter has left in it.
You'll need precise instructions on using your gas mask
You should be clean-shaven when putting on your gas mask. A beard (or even stubble) may enable the poisons to infiltrate the mask.
If you've had no training in the use of gas masks
Some gas mask
Increasingly, gas masks are available in various sizes - even for children and babies. If you're buying gas masks for your family, then be sure that each one has a perfect fit. Some masks are equipped with drinking systems, and masks that enable easier speech (via 'voice-mitter') are also available.
Don't buy masks via mail-order or over the Internet as you can't be sure that they'll fit properly. Always buy them in person from a professional who knows what he/she is talking about. Be sure to get a mask fitted for everyone in the family. To my knowledge, there are currently no gas masks
Bear in mind that, while gas masks
Generally, for biological agents to be effective, they need to be between 1 and 5 microns in diameter. For this reason, regular surgical masks, which are relatively cheap, would protect you against almost all biological threats. Protection against chemical agents, however, requires a gas mask.
If you have a baby or a young infant who is reluctant to put on a gas mask
There are a number of important points to bear in mind when buying a gas mask:
While there have been some advances lately in the production of gas masks for women, children and people with smaller faces, a lot of the masks on the market are designed with the adult male (military) face in mind.
Be sure to buy a mask that fits perfectly otherwise it will only give you a false sense of security (there's no point in a filter that keeps out bacteria at 0.3 microns if you've got 1mm of space between your face and the mask (which is why you have to be clean-shaven before putting on the mask). Of course, you would need to have a mask fitted individually for every member of your family.
Make sure that your gas mask
Don't buy your gas mask from surplus 'Army-Navy' type stores. The gas masks you'll find here have most likely been used in military exercises, may be out of date and very possibly contain flaws in the structure (small cracks or holes in the rubber). If you are buying a mask, buy one from a reputable manufacturer and buy it in person with every member of your family available for a fitting.
The best masks are those with HEPA filter* (ideally coupled with chromium-free impregnated carbon, that filters both inorganic warfare agents like cyanide, chlorine and phosgene, as well as organic agents like VX, sarin, tabun, mustard gas and lewisite). Some gas masks can even protect you against acid gases and ammonia.
Protective Suits
Appropriate protective clothing can prevent exposure through the skin.
Protective suits
Several sizes exist, including those for children.
Protective boots are usually designed especially to accommodate the extra bulk of a protective suit, and remain relatively easy to put on even if you're wearing protective gloves. Protective boots are usually knee high and have a high chemical resistance.
Protective gloves are extremely solid, they can be as thick as 25mm and have a particularly long chemical resistance, resisting most toxic/hazardous chemicals.
Like gas masks, I would need to question the practicality of buying protective suits. Obviously, you wouldn't be able to carry one around with you everywhere you go (you're kids would definitely draw the line on that one!), and the cost of keeping a suit everywhere is prohibitive.
And, like gas masks, you would need to know about the attack in time to get the suit on. And again, you may be putting yourself in danger as you struggle to put on the suit when you could, instead, be making sensible efforts to escape the gas cloud
