Thorium (chemical symbol Th) is a naturally-occurring radioactive metal found at very low levels in soil, rocks, and water. It has several different isotopes, both natural and man-made, all of which are radioactive. The most common form of thorium is thorium-232, found naturally. ... Thorium-232 has a half-life of 14 billion (14 x 109) years, and decays by alpha emission, with accompanying gamma radiation. Thorium-232 is the top of a long decay series that contains key radionuclides such as radium-228, its direct decay product, and radon-220. ...

«famille(ou série) radioactive» : Nom donné aux 4 séries de nucléides radioactifs dont chacun se déduit du précédent par désintégration nucléaire spontanée et dont les pères nucléaires sont respectivement le thorium 232, le neptunium 237, l'uranium 238 et l'uranium 235. Chaque série aboutit à un produit terminal stable. Ces 4 familles radioactives sont appelées familles du thorium, du neptunium, de l'uranium et de l'actinium et les nombres de masse des éléments qui composent chacune d’elles sont respectivement de la forme 4 n, 4 n + 1, 4 n + 2 et 4 n + 3.
