Nuclear weapon - Nuclear weapon - Residual radiation and fallout: Residual radiation is defined as radiation emitted more than one minute after the detonation. They disintegrate due to a fix in their internal structure. A nucleus will regain stability by emitting alpha or beta particles and then 'cool down' by emitting gamma radiation. The heat produced in the fission process powers steam turbines, which in turn power generators that give us electricity. Examples include lethal effects to individuals, radioactive isotope to the environment, or reactor core melt." Radioactive decay occurs in unstable atomic nuclei. Nuclear radiation arises from hundreds of different kinds of unstable atoms. Radiation exists naturally in very low levels that the human body and the environment can sustain without being harmed. Nuclear radiation is the energy given off by all radioactive elements when they break down into more stable atoms.
