e. Nuclear fallout is residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. [1] It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes.
Much of the destruction caused by a nuclear explosion is from blast effects. Most buildings, except reinforced or blast-resistant structures, will suffer moderate damage when subjected to overpressures of only 35.5 kilopascals (kPa) (5.15 pounds-force per square inch or 0.35 atm).

A nuclear electromagnetic pulse (nuclear EMP or NEMP) is a burst of electromagnetic radiation created by a nuclear explosion. The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges. The specific characteristics of a particular nuclear EMP event ...
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.
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
As the incendiary effects of a nuclear explosion do not present any especially characteristic features, [36] it is estimated by those with strategic bombing experience that as the city was a firestorm hazard, the same fire ferocity and building damage produced at Hiroshima by one 16-kiloton nuclear bomb from a single B-29 bomber could have been ...
Preliminary dose-estimation reports by the World Health Organization and the United Nations Scientific Committee on the Effects of Atomic Radiation indicate that 167 plant workers received radiation doses that slightly elevate their risk of developing cancer, but that this risk may not be statistically detectable, as has happened in the case of the Chernobyl nuclear disaster.
