Rain radiation falls relatively quickly over time. Most areas become quite safe to travel and decontaminate after three to five weeks. Remove contaminated clothing and clean or wash unprotected skin if you were outside after the rain hit. Hand sanitizer doesn't protect against falls.
If possible, avoid touching your eyes, nose, and mouth. Do not use disinfectant wipes on your skin. Take a shower or wash with soap and water to wash away rain from any skin or hair that isn't covered. If you can't wash or shower, use a clean, damp washcloth or cloth to clean uncovered skin or hair.
The CDC website provides information on the radioactive consequences of nuclear weapons tests conducted in the atmosphere around the world (global weapons tests) during the 1940s and 1950s. A nuclear electromagnetic pulse (PEM) is the time-varying electromagnetic radiation that results from a nuclear explosion. The Comprehensive Nuclear-Test-Ban Treaty (CTBT) The CTBT is a legally binding global ban on the testing of nuclear explosives. When a nuclear detonation occurs, people, plants and animals can be exposed to rain in a variety of ways.
Even though there is still very little rainfall in the environment, it's important to remember that rain can be very dangerous. Based on these estimates, the consequences of the more than 500 megatons of nuclear tests until 1970 will produce between 2 and 25 cases of genetic diseases per million live births in the next generation. That is, until one of them Googled the safety nuclear bomb how to shelter from the beach and found a Business Insider article titled If a nuclear bomb explodes, this is the most important thing you can do to survive. This web page provides information on the radioactive consequences of nuclear weapons tests in the atmosphere conducted during the 1940s and 1950s.
Treaty Banning Nuclear Weapons Testing in the Atmosphere, in Outer Space and Under Water The 1963 Test Ban Treaty prohibits the testing of nuclear weapons “or any other nuclear explosion in the atmosphere, in outer space and under water. An example is the 1962 report of the Federal Radiation Council, entitled “Health Implications of Fallout from Nuclear Weapons Testing through 1961.It also provides a brochure from the 1950s on the consequences and several images related to nuclear weapons testing and rain shelters. The highest levels of outdoor rain radiation occur immediately after the arrival of rain and then decrease over time. Since large doses of radiation of approximately 20 roentgen or more (see radioactivity note) are needed to produce developmental defects, these effects would likely be limited to areas of heavy local rainfall in nuclear warring nations and would not become a global problem.
The 1963 Limited Nuclear-Test-Ban Treaty ended atmospheric testing for the United States, Great Britain and the Soviet Union, but two major non-signatories, France and China, continued nuclear testing at a rate of approximately 5 megatons per year.
