Naturally occurring samarium (62 Sm) is composed of five stable isotopes, 144 Sm, 149 Sm, 150 Sm, 152 Sm and 154 Sm, and two extremely long-lived radioisotopes, 147 Sm (half life: 1.066 × 10 11 y) and 148 Sm (6.3 × 10 15 y), with 152 Sm being the most abundant (26.75% natural abundance).

As of 7 Jan 2023, the "Main isotopes of <element>" tabular list will be read directly from the Isobox: "Infobox <element> isotopes". For example, {{Infobox uranium}} will read the table live from {{Infobox uranium isotopes}}. The headerbar provides View-Edit links to that Isobox.
As the longest-lived radioactive isotope ruthenium-106 has a half-life of only 373.59 days, it has been suggested that the ruthenium and palladium in PUREX raffinate should be used as a source of the metals after allowing the radioactive isotopes to decay. [4] [5] After ten half life cycles have passed over 99.96% of any radioisotope is stable ...

This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
