Although thorium (90Th) has 6 naturally occurring isotopes, none of these isotopes are stable; however, one isotope, 232Th, is relatively stable, with a half-life of 1.405--1010 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe.
