6 EQUATIONS OF RADIOACTIVE DECAY AND GROWTH

www-naweb.iaea.org

6.6 RADIOACTIVE DECAY SERIES If a radioactive nuclide is situated in the Chart of Nuclides far from the stability line (for the light elements at Z=N), the daughter nucleus after radioactive decay may be radioactive as well. In nature this occurs with the heavy nuclides in the uranium and thorium decay series (Chapter 12).

Algebraic Equations for Radioactive Decay

hydra.smith.edu

1. The number of radioactive atoms of a given type decaying in one unit of time is proportional to the number of radioactive atoms present. This assumption has been verified by observation for short-lived radioactive isotopes. 2. The decay constant (λ) has not changed during geologic time and remains constant

Radioactive decay is the process in which an unstable nucleus spontaneously loses energy by emitting ionizing particles and radiation. This decay, or loss of energy, results in an atom of one type, called the parent nuclide, transforming to an atom …
