For a complete list of the 35 known primordial radionuclides, including the next 28 with half-lives much longer than the age of the universe, see the complete list below. For practical purposes, nuclides with half-lives much longer than the age of the universe may be treated as if they were stable. Rb, Re, Lu, Th, and U have half-lives long enough that their decay is limited over geological time scales; K and U have shorter half-lives and are hence severely depleted, but are still long-lived enough to persist significantly in nature.
1919:—bismuth (83), thorium (90), and uranium (92). If plutonium (94) turns out to be primordial (specifically, the long-lived isotope Pu), then it would be a fourth radioactive primordial, though practically speaking it would still be more convenient to produce synthetically. Bismuth's half-life is so long that it is often classed with the 80 primordial stable elements instead, since its radioactivity is not a cause for serious concern. The number of elements is smaller than the number of nuclides, because many of the primordial elements are represented by multiple

Mathematically, considering the likely initial abundances of these nuclides, primordial Sm and Pu should persist somewhere within the Earth today, even if they are not identifiable in the relatively minor portion of the Earth's crust available to human assays, while Nb and all shorter-lived nuclides should not. Nuclides such as Nb that were present in the primordial solar nebula but have long since decayed away completely are termed

These 35 primordial nuclides represent radioisotopes of 28 distinct chemical elements (cadmium, neodymium, osmium, samarium, tellurium, uranium, and xenon each have two primordial radioisotopes).
