It has a half life of 14.05 billion years, which makes it the longest-lived isotope of thorium. It decays by alpha decay to radium-228; its decay chain terminates at stable lead-208. Thorium-232 is a fertile material; it can capture a neutron to form thorium-233, which subsequently undergoes two successive beta decays to uranium-233, which is ...
The scale is radioactive because of the presence of thorium and radium, which occur naturally in the rare-earth ore. A federal investigation later found that some 60 spills—some unreported—occurred between 1984 and 1998, when the pipeline and chemical processing at the mine were shut down. [23]
This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.

Tho-Radia powder box "made after Dr Alfred Curie's formula" at Musée Curie in Paris.. Tho-Radia was a French pharmaceutical company making cosmetics between 1932 and 1968. . Tho-Radia-branded creams, toothpastes and soaps were notable for containing radium and thorium until 1937, as a scheme to exploit popular interest for radium after it was discovered by Pierre and Marie Curie, in a fad of ...
It was once named Radiothorium, due to its occurrence in the disintegration chain of thorium-232. It has a half-life of 1.9116 years. It undergoes alpha decay to 224 Ra. Occasionally it decays by the unusual route of cluster decay, emitting a nucleus of 20 O and producing stable 208 Pb. It is a daughter isotope of 232 U in the thorium decay series.
It processed ores like monazite to produce elements, including thorium and uranium. It also made gaslight mantles, and during World War II, hydrofluoric acid. [11] In 1958, it became owned by American Potash and Chemical Company (AMPOT), [11] which at one point had a 'Lindsay Chemical Division.' [4]
Thorium resources are the estimated mineral reserves of thorium on Earth. Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been ...
