If the radioactive decay of Thorium- (232 with Th and Pb as their atomic proportions and λ Th232 is the appropriate decay constant. This equation can be turned around to give: (2) t = ln Pb / 232 Th + 1 / λ Th 232 which permits the age t to be determined from the measured concentrations of Pb and Th. 54 rows 232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th. The half-life of 233 Th is approximately 21.8 minutes.

Its radioactive series contains ten daughter radionuclides and is as follows:. 1 Jan 1995 This induces a strong disequilibrium in the decay chain of Thorium 232, and, as a result, more than 80 % of the total alpha-emission of Ultra-pure.

When bombarded with neutrons, thorium-232 becomes thorium-233, which eventually decays into uranium -233 through a series of beta decays. Uranium-233 is a fissionable material and can be used as a nuclear fuel.

(a) 239 Pa (b) 238 Pa (c) 239 Ac (a) 238 AC Ra Thorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides. 232 Th decays via alpha decay into 228 Ra . Write a balanced nuclear equation for the decay of each of the following. thorium-232 undergoing alpha decay.
