Detailed explanation-1: -Radioactive Decay-Disintegration of the nucleus of an unstable atom by the release of radiation. Radiation-Energy moving in the form of particles or waves. Familiar radiations are heat, light, radio waves, and microwaves. Ionizing radiation is a very high-energy form of electromagnetic radiation.

Detailed explanation-2: -Radioactive Decay This radiation can be emitted in the form of positively charged alpha particles, negatively charged beta particles, gamma rays, or x-rays, as explained below. Through this process-called radioactive decay-radioisotopes lose their radioactivity over time.

Detailed explanation-3: -When it decays, a radionuclide transforms into a different atom-a decay product. The atoms keep transforming to new decay products until they reach a stable state and are no longer radioactive.

Detailed explanation-4: -Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive.

Detailed explanation-5: -Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.
