WebSep 12, 2024 · When an individual nucleus transforms into another with the emission of radiation, the nucleus is said to decay. Radioactive decay occurs for all nuclei with Z > 82, and also for some unstable isotopes with Z < 83. The decay rate is proportional to the number of original (undecayed) nuclei N in a substance.
