Kinetics of Radioactive Decay

  • Gopal B. Saha


As mentioned in Chapter 2, radionuclides decay by spontaneous fission, α-, β -, and β +-particle emissions, electron capture, or isomeric transition. The radioactive decay is a random process, and it is not possible to tell which atom from a group of atoms disintegrates at a specific time. Thus, one can only talk about the average number of radionuclides disintegrating during a period of time. This gives the disintegration rate of a particular radionuclide.
