Related to Decay rate: radioactive decay rate

radioactive decay

n.
1. Spontaneous disintegration of a radionuclide with the emission of energetic particles or radiation, such as alpha or beta particles or gamma rays.
2. An instance of such disintegration.

radioactive decay

n
(Nuclear Physics) disintegration of a nucleus that occurs spontaneously or as a result of electron capture. One or more different nuclei are formed and usually particles and gamma rays are emitted. Sometimes shortened to: decay Also called: disintegration

ra·di·o·ac·tive decay

(rā′dē-ō-ăk′tĭv)
The spontaneous breakdown of a radioactive nucleus into a lighter nucleus. Radioactive decay causes the release of radiation in the form of alpha particles, beta particles, or gamma rays. The end result of radioactive decay is the creation of a stable atomic nucleus.

radioactive decay

The decrease in the radiation intensity of any radioactive material with respect to time.
