WebDecay heat is the heat released as a result of radioactive decay.This heat is produced as an effect of radiation on materials: the energy of the alpha, beta or gamma radiation is converted into the thermal movement of atoms.. Decay heat occurs naturally from decay of long-lived radioisotopes that are primordially present from the Earth's formation. WebEarth’s heat comes from two main sources: physical processes early in its formation, and radioactive decay. Physical Processes that Heated Earth. Formation processes contributed heat in the following ways: Heat came from the thermal energy already contained within the objects that accreted to form Earth.
