Note: The calculation of radioactivity in minerals is based on certain assumptions. All are present, at least transiently, in any natural thorium-containing sample, whether metal, compound, or mineral. The series terminates with lead-208. The details in decay chain (symbol, atomic mass, number of protons, half-life, decay children) are taken from Wikipedia.

Se hela listan på epa.gov Se hela listan på whatisnuclear.com Thorium reactors work by breeding Th-232 through Protactinium-233 (27.4 day half life) and into Uranium-233, which is fissile. Pa-233 is a pretty strong neutron absorber, so the MSBR (basically the LFTR) has to extract it from the core once it is produced and let it decay to U-233 away from the neutrons. Se hela listan på periodic.lanl.gov 2016-01-31 · Radon-220 (also known as thoron) is a short-lived isotope of radon and originates from thorium present in the earth’s crust. The Rn-220 isotope is a natural decay product of the most stable thorium isotope (Th-232), and is commonly referred to as thoron.

There is actually no single answer to this question, because Thorium has several isotopes, each with its own half-life. In order of atomic weight, these are: Th228: half-life 1.9 years Th230: half A 12 gram sample of Thorium - 232 was found to be 42.3 billion years old.

Thorium, Th, is the name of element 90. It is an actinide, a seventh-period f-block element. Thorium is common enough for minerals in which Th is the predominant metal to exist. It is also radioactive, but its principal isotope, Th 232, has a half-life exceeding 14 billion years, which means slightly less than half of any Th 232 which formed in the early universe still exists. This element is

Thorium is the 41st most abundant element in the Earth's crust. Natural thorium is usually almost pure 232 Th, which is the longest-lived and most stable isotope of thorium, having a half-life comparable to the age of the universe.
