In nature, virtually all thorium is found as thorium-232, which undergoes alpha decay with a half-life of about 14.05 billion years. As far as nations go, Canada, China, Germany, India, the Netherlands, the United Kingdom and the United States have all experimented with using thorium as a substitute nuclear fuel in nuclear reactors.

Thorium-232 and uranium-238 are the only two naturally occurring fertile materials. Thorium-232 decays by alpha decay. Part of the nuclear equation is shown below. Fill in the blank with a number. 232/90 - 11546309 The 4n chain of Th-232 is commonly called the "thorium series" or "thorium cascade".
