The alpha decay of 232 Th initiates the 4n decay chain which includes isotopes with a mass number divisible by 4 (hence the name; it is also called the thorium series after its progenitor). This chain of consecutive alpha and beta decays begins with the decay of 232 Th to 228 Ra and terminates at 208 Pb.

The Rn-220 isotope is a natural decay product of the most stable thorium isotope (Th-232), and is commonly referred to as thoron. It has a half-life of 55.6 seconds and also emits alpha radiation.

thorium-232 decays and produces an alpha particle and a radium-228 nucleus, which decays into actinium-228 by beta decay. Radioactive Decay Process:

As Thorium-234 undergoes beta decay, a neutron becomes a proton.

How it works: We use thorium (in thorium oxide) to generate thoron. The sequence of decays is known as the Thorium-232 series and goes as follows: The thorium series is one of three classical radioactive series beginning with naturally occurring thorium-232.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. For example, pure thorium-232 is weakly radioactive (proportional to its long half-life), but a thorium ore is about 10 times more radioactive than the pure thorium-232 metal because of its daughter isotopes (e.g. radon, radium etc.) it contains.

Most of the natural radioactivity is caused by radionucluides in the decay series starting with uranium-238, uranium-235, thorium-232 and potassium-40.

Thorium oxide is used as a catalyst in the production of sulfuric acid (H 2 SO 4), in the cracking of petroleum products and in the conversion of ammonia (NH 3) to nitric acid (HNO 3). Thorium's most stable isotope, thorium-232, has a half-life of about 14,050,000,000 years. It decays into radium-228 through alpha decay or decays through

It decays into radium-228 through alpha decay or decays through Thorium is a naturally occurring, radioactive substance. In the environment, thorium exists in combination with other minerals, such as silica. Small amounts of thorium are present in all rocks, soil, water, plants, and animals.Soil contains an average of about 6 parts of thorium per million parts of soil (6 ppm).

More than 99% of natural thorium exists in the form of thorium-232. It breaks down into two parts-a small part called "alpha" radiation and a large part called the decay product. The decay product is also not stable and continues to break down through a series of decay products until a stable product is formed.

Thorium-232 is not a stable isotope. As thorium-232 decays, it releases radiation and forms decay products that include radium-228 and thorium-228. The decay process continues until a stable, nonradioactive decay product is formed. In addition to thorium-232, thorium-228 is present naturally in background. Thorium-228 is a decay product of radium-228, and thorium-228 decays into radium-224.
