Thorium is also used to coat tungsten filaments used in electronic devices, such at television sets. When bombarded with neutrons, thorium-232 becomes thorium-233, which eventually decays into uranium -233 through a series of beta decays. Uranium-233 is a fissionable material and can be used as a nuclear fuel.

Isotope 232 Th belongs to primordial nuclides and natural thorium consists primarily of isotope 232 Th. Other isotopes (230 Th, 229 Th, 228 Th, 234 Th and 227 Th) occur in nature as trace radioisotopes, which originate from decay of 232 Th, 235 U and 238 U. 2006-07-09 · The thorium decay series begins with Th-232, which has a radioactive half-life of 13.9 billion years, and ends with the formation of Pb-208, a stable isotope. In the transmutation of the parent thorium to the stable lead, a total of 10 other radioisotopes are formed. Thorium is also used to coat tungsten filaments used in electronic devices, such at television sets. When bombarded with neutrons, thorium-232 becomes thorium-233, which eventually decays into uranium -233 through a series of beta decays. Uranium-233 is a fissionable material and can be used as a nuclear fuel.

A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor.

We use thorium (in thorium oxide) to generate thoron. The sequence of decays is known as the Thorium-232 series and goes as follows: Note that a lesser branch at ThC by α decay to ThC (81 Tl 208), and then to lead-208 by β decay, has been omitted here.

Thorium-232 is not a stable isotope. As thorium-232 decays, it releases radiation and forms decay products that include radium-228 and thorium-228. The decay process continues until a stable, nonradioactive decay product is formed. In addition to thorium-232, thorium-228 is present naturally in background. Thorium-228 is a decay product of radium-228, and
