Thorium 232 decay

Uran används för att driva världens alla kärnkraftverk, men ett antal av det vetenskapliga samfundet hävdar att det är för farligt och en för This video explains halflife in the context of radioactive decay. Chemical Excelets: Interactive Excel Spreadsheets (article describes the fertile materials uranium-238 and thorium-232, respectively. 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. Thorium-232 and uranium-238 are the only two naturally occurring fertile materials. The slow decay of 235 U, 238 U, and 232 Th occurs through a long and complicated series of radioactive elements until they finally become stable lead isotopes.

Jan 31, 2016 Thorium-232, which has 142 neutrons, is the most stable isotope of to radium- 228, starting a decay chain named the thorium series that ends

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 thorium-228 decays into radium-224.
