The principles of radiation protection are easy, and everyone is able to equip the shelter that will reliably protect her. Forget the myth that if a nuclear attack is impossible to survive and see less informed people.
The fallout - a particulate matter (dust) that are released by a nuclear explosion and rise high in the air in the form of a mushroom-like cloud. The wind carries clouds of dust, some of it settles on the ground, to the territory downwind from the explosion site. The most severe, the most dangerous and the most notable of them will fall closest to the so-called "zero point" - place a bomb. Fallout usually begins a few minutes after the explosion. Lighter and smaller Similar to dust particles begin to settle to the ground a few hours later, they rise up into the air and moved much farther downwind, often for hundreds of kilometers. When a cloud, everything should fall, usually falls in less than an hour, and then spreads everywhere, like an ordinary dust.
If shortly after the explosion starts to rain, keep in mind that it may bring more radioactive fallout than the wind, and where they will settle on the ground with the rain, the radiation level may be higher than elsewhere, although the eye is, of course It will not be noticeable.
Radioactive dust is dangerous because it emits radioactive energy, according to the principle of action similar to X-rays. Unlike precipitation in the form of dust, radiation

able to pass through walls, roofs and protective clothing. Even if you can not breathe or swallow dust and avoid its contact with skin, hair and clothes, and even if you do not give her to get into the house, the radiation can still hurt you or even kill you in the house.
The radioactive fallout from a nuclear explosion, is very dangerous in the beginning, very quickly emit huge amounts of energy and just as quickly become less intense. This means that you and your family be able to survive, if you can wait a certain time in a safe shelter.
Speaking quite simply, to protect against radiation, it is necessary that between you and the source of it was as much a solid mass. How vest stopped the bullet, so solid mass stops (or rather absorb) radiation. The thicker you make the walls of his shelter, the safer it becomes. The thickness of the materials required to reduce emission to 1/10 of its original intensity: steel - 8.38 cm concrete - 27.94 cm soil - 40.64 cm, water - 60.96 cm, wood - 96.52 cm.
And to hold 99% of radiation is needed: 12.70 cm steel 40.64 cm solid brick or hollow concrete blocks filled with lime or sand, compacted soil 61 cm or 91 cm are not compressed, 91 cm of water. You may not be enough steel, but all that will be at your fingertips, suitable for enhancing your protection - simply to absorb the same amount of radiation you need a larger amount of light wood, than, say, rammed earth. Increasing the distance between the people inside the shelter and radiation outside also reduces the intensity of the radiation exposure.
General requirements for asylum:
- It should provide, where possible, the maximum distance between the people who are in hiding, and precipitation in the form of dust, which are on the ground, on rooftops and in trees
- The walls shall be sufficiently thick and dense that absorb lethal radiation
- The shelter should be more or less comfortable to stay before the radiation level down
In principle, asylum can build anywhere, but it is best to use the opportunities available to you at home or close to it.
Consider using structures located far from your home, especially where there are underground facilities, such as commercial buildings, schools, churches, underground parking, wide and long culverts, tunnels. Think about this in advance, so that their use may need permission. Also, you may need additional materials, to reduce the risk of penetration into the shelter of hazardous particles.
The central premise of average floors of buildings with six or more floors can provide good protection from radiation. Distance from the exterior walls and the walls themselves will protect the people who had taken refuge there from the gamma radiation of radioactive particles deposited on the ground and on the roof.
If you or your family and friends there is a cellar, the best option - to strengthen and use it. (Unless you have no access to a reliable and deep refuge nearby).
If you urgently need to hide in the basement, push the heavy table in the corner, who is the deepest underground. Ideally, the ground level outside should be above the table top, standing inside the shelter. If you do not have a heavy table, remove the interior doors and put them in any kind of props to get a table. Then overlaid on top of the table with two open sides of all that you will find; suitable books, firewood, boards, bricks, sand bags, heavy technical devices, complete folders, canisters filled with water, food supplies, even boxes and pillowcases filled with something heavy, such as soil. All that you can pile up on top and sides, and has a mass density and be able to stop and absorb a greater amount of radiation; heavier items that you use, the better. However, be sure to make sure that the table has been sufficiently reinforced, so it does not hit you on the head.
Leave a small hole, enough to get through it to the shelter by crawling and some things from the outside, which you can easily close the entrance. Leave a small opening from the top - it will go through the exhaled air. Another hole, about 4x4 cm and leave low - through the air will come in. If a lot of people in the shelter, or where you are in a hot climate or warm season, do a vent larger. If necessary, the air can be made to circulate faster, waving a piece of paper or cardboard as a fan. When all the holes in the basement of a well-closed, the incoming air filter is not necessary.
To enhance the protective functions of your walls of the basement shelter can sprinkle the ground outside and impose something heavy inside. We remind you that each additional centimeter of solid mass increases your chances of surviving a nuclear catastrophe with minimal losses.
No matter how close it was not your shelter if you have the opportunity to further seal the wall, making it even more closely - do not hesitate because every extra bag of sand may be crucial to your survival and health.
Most people who need shelter, will be located at a distance of several kilometers from the site of the explosion, and they do not need to stay in the shelter for weeks. In fact, most people will have to stay there for a few days and then it will be possible to start a while to come out. Still later, it will be possible to spend more time outside the shelter and go back just to sleep. This may seem like a terrible inconvenience, but no doubt you and your family soak it, especially if you compare the situation with the alternatives available.
Important details
If you follow the instructions in the previous paragraph: bought food and other essentials, stocked with water and built a shelter, you have increased the chances of survival of their families more than a hundred times! Now you need to expand their knowledge, which will be the basis of your family survival strategy.
