A sequence of radioactive decay processes, in which the decay of one element creates a new element that may itself be radioactive. The chain ends when stable atoms are formed. For example, uranium-238 decays into thorium-234, which in turn decays into palladium-234, and so on until stable iron is produced at the end of the chain.
