Hello! Thoron is a radioactive isotope of radon Rn. It is a naturally occurring radioactive gas that is not normally released into the atmosphere at the earth's surface or is found within liquid solutions such as water and soil. About 16% of the total volume of air contains thoron. In other words, thoron, being a long-lived radioactive



Thoron is a radioactive element of artificial origin, which is a mixture of the isotopes Ba-133 and Ba-117. It was first synthesized in 1958 at the University of California, Berkeley laboratory. This element has an important role in medicine, as it is used to produce radioisotope drugs such as gamma-methoxaline, which is used to treat cancer of various locations.

Thoron is a product of fission of the atomic nucleus, during which alpha particles and electrons are emitted. It can be obtained by the nuclear reaction of the nucleus of a thorium-232 atom with the nuclei of an atom of the element fluorine-196. As a result of this interaction, an element is formed
