Diagram of the nuclear decay chain of thorium-232 (Th-232) with isotopes (shown by chemical symbols) plotted by mass number (A) against atomic number (Z). Isotopes are colour-coded by their primary decay route (purple, red arrows: alpha decay; blue, blue arrows: beta decay). Thorium is an element that occurs naturally in the earth's crust. The only naturally occurring isotope of thorium is 232 Th and it is unstable and radioactive. According to Adams and Gasparini (1970) thorium is chemically stable in the tetravalent ion state under reducing conditions, has a large ionic radii, a high coordination number (8) with respect to oxygen, and complete outermost electron shells.

Thoron Decay Chain: Th-232 is commonly called the "thorium series." Beginning with naturally occurring thorium-232, this series includes the following elements: actinium, bismuth, lead, polonium, radium, and radon. All are present, at least transiently, in any natural thorium-containing sample, whether metal, compound, or mineral.

Due to 5α particle, z will change by 10 unit. Since given Uranium-238 decays into thorium-234, which is also a radioisotope. Nuclear Decay Write a balanced nuclear equation for the alpha decay of thorium-232. Radon-220 decay chain. 220Rn is a decay product of the long-lived 232Th isotope. The half life of 232Th is 14 billion year.

Radiogenic radionuclides are produced by alpha- and beta transformations, though many of these radionuclides are also gamma emitters.

All are present, at least transiently, in any natural thorium-containing sample, whether metal, compound, or mineral. Thorium-227 has a physical half-life of 18.7 days. Thorium-227 decays to Ra-223 and other short-lived radionuclides in its decay chain to stable lead-207.
