What is radioactive fallout, and how to avoid it?
Radioactive fallout is dangerous particles that spread in the air after an explosion and then fall to the ground. These particles release radiation, which is very dangerous. To avoid it, remember three things:Distance: The further away from the fallout, the better. If you are far from the explosion, the less danger you will have.Shielding: Thick and strong objects, such as concrete, brick, soil or a pile of books, can block radiation. So hide in a place with thick walls.Time: Fallout radiation is most dangerous in the first few hours and days. If you stay in a safe place for the first 24-48 hours, the danger is greatly reduced.Which is the best shelter?The best shelter to avoid radioactive fallout is below ground. If you have a basement, that is good. Cover basement windows with sandbags or thick objects. If you have a special fallout shelter, that's even better. These shelters are built with thick walls and roofs that block radiation. For example, 3 feet of soil can block 99.99% of radiation.Does potassium iodide (KI) protect against radiation?Potassium iodide (KI) only protects the thyroid gland from radioactive iodine. It does not protect against other types of radioactive substances or external radiation. KI should only be taken if government or health officials say so. This is especially true for people under the age of 40, pregnant women, and children. Taking the wrong amount of KI can be harmful.How long should you stay in the shelter?This depends on how much fallout is in your area. The most dangerous time is the first 24-48 hours. In some places, you may have to stay in the shelter for 2 weeks or more. Listen to government news on a battery radio. Go out only when the government says it is safe to go out.A nuclear explosion is very dangerous, but with the right information and preparation, you can protect yourself and your family. Take shelter immediately, hide in a strong place, and keep emergency supplies ready. Listen to the news on the radio and follow government instructions. If we are prepared in advance, we can stay safe even in difficult times.
