- Definition any of four independent sets of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved: thorium series, uranium series, actinium series and neptunium series Reference Britannica: http://www.britannica.com/EBchecked/topic/489075/radioactive-series (24.09.2014)
- Comment These four chains of consecutive parent and daughter nuclei begin and end among elements with atomic numbers higher than 81, which is the atomic weight of thallium; the members of each set are genetically related by alpha and beta decay. Three of the sets, the thorium series, uranium series, and actinium series, called natural or classical series, are headed by naturally occurring species of unstable nuclei. The fourth set, the neptunium series, is headed by neptunium-237. Its members are produced artificially by nuclear reactions and do not occur naturally.
