Many naturally-occurring radioisotopes ( another 51 or so, for a total of about 339 ) exhibit still shorter half-lives than 80 million years, but they are made freshly, as daughter products of decay processes of primordial nuclides ( for example, radium from uranium ) or from ongoing energetic reactions, such as cosmogenic nuclides produced by present bombardment of Earth by cosmic rays ( for example, carbon-14 made from nitrogen ).

Natural processes which produce trace radioisotopes include cosmic ray bombardment of stable nuclides, ordinary alpha and beta decay of the long-lived heavy nuclides, Thorium-232, Uranium-238, and Uranium-235, spontaneous fission of natural Uranium-238, and nuclear transmutation reactions induced by natural radioactivity, such as the production of Plutonium-239 and Uranium-236 from neutron capture
