Fission gamma rays

WebResidual radiation is defined as radiation emitted more than one minute after the detonation. If the fission explosion is an airburst, the residual radiation will come mainly from the weapon debris. If the explosion is on or near the surface, the soil, water, and other materials in the vicinity will be sucked upward by the rising cloud, causing early (local) … Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei.
