The residual radiation is emitted after the initial attack from materials that were impacted by the detonation. These materials let off nuclear radiation in the form of residual radiation. [8] In the event of a nuclear attack, a human body can be irradiated by at least three processes.
The intermediate time scale is between 1 and 30 days, with long term fallout occurring after that. Examples of both intermediate and long term fallout occurred after the 1986 Chernobyl accident, which contaminated over 20,000 km 2 (7,700 sq mi) of land in Ukraine and Belarus.

These effects could last up to 12 hours after the exposure. Due to the long exposure time needed to see any of these effects it is unlikely that anyone would see these effects even if exposed for a small period of time. Also, the human body will see little effect as signals are passed chemically and not electrically making it hard to be ...
Regardless, Buddemeier says sheltering in place for at least 12 to 24 hours is a key way to survive the threat of fallout, since that's how long the worst of this radiation usually lasts.
4. Don't Rush Outside Right After A Bombing After an air burst, wait a few minutes then go help to fight fires. After other kinds of bursts wait at least 1 hour to give lingering radiation some chance to die down. 5. Don't Take Chances With Food Or Water In Open Containers To prevent radioactive poisoning or disease, select your food and water ...
Born in New York City on Dec. 24, 1945 — four months after the U.S. detonated nuclear weapons over Hiroshima and Nagasaki, effectively ending World War II — Meyer grew up in the shadow of the ...
The 2011 Fukushima Daiichi nuclear disaster, the worst nuclear incident in 25 years, displaced 50,000 households after radioactive material leaked into the air, soil and sea. [1] Radiation checks led to bans on some shipments of vegetables and fish. [2] Map of contaminated areas around the plant (22 March – 3 April).
