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

Because Including all the succeeding decays, the total activity in the thorium-232 and uranium-238 series is, very roughly, ten times the activity indicated for thorium- 232 The radioactive decay series of 232Th is complex and produces alpha, beta, and gamma radiation. The figure below shows the important isotopes in the decay 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 protection are the radionuclides in the U-238 and Th-232 decay series.

November, 23rd 2010 Serena Risica, Francesco Bochicchio and Cristina Nuccetelli Istituto Superiore di Sanità (National Institute of Health) Rome, Italy 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. The radioactive decay series of 232 Th is complex and produces alpha, beta, and gamma radiation. The figure below shows the important isotopes in the decay series, indicates whether the primary decay mode is via alpha or beta emission, and gives the half-life. 232 Th decay chain.

This chain of consecutive alpha and beta decays begins with the decay of 232 Th to 228 Ra and terminates at 208 Pb. As already stated earlier, radiogenic radionuclides are part of three decay series, which all start with decay of primordial isotopes of uranium (235 U, 238 U) and thorium (232 Th). Interestingly, each series contains a radioactive isotope of radon, namely, actinon (219 Rn), thoron (220 Rn), and radon (222 Rn) and ends with a stable isotope of lead.

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. In case of thorium series, the stable nucleus is lead-208.

2016-01-31 · Thorium-232, which has 142 neutrons, is the most stable isotope of thorium and accounts for nearly all natural thorium, with the other five natural isotopes occurring only in traces: it decays very slowly through alpha decay to radium-228, starting a decay chain named the thorium series that ends at lead-208.

It will, in about 14.1 BILLION years decay and became stable Lead 208 Decay chain - Wikipedia If you expose Thorium 232 to neutron flux, some Thorium A well-known example is the thorium decay chain that produces uranium-233, which is always accompanied by uranium-232, of which the decay product produces strong gamma radiation, which is highly destructive to ordnance components, circuitry, and personnel, making it very difficult to work with. Radium-228 has a half-life of (5.75 years) and decays by emitting a beta particle. It is a radioactive decay product in the thorium-232 decay series, a very difficult and complex decay chain: 232 Th→ 228 Ra → 228 Ac → 228 Th → 224 Ra → 220 Rn → 216 Po → 212 Pb → 212 Bi → 208 Tl → 208 Pb(stable); with a sub-branch of 212 Bi → 212Po → 208 Pb(stable).
