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

US EPA: Document on Radioactive Decay of Thorium-232 The decay series for the transformation of thorium-232 to lead-208 is shown in the EPA document whose link is shown above. (2 points) Write a balanced nuclear equation for each reaction shown. 232/90 Th 208/82 Pb 24/8 Place your answer to the following questions in the table below.

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. Answer to: In the thorium decay series, thorium-232 loses a total of 6 alpha particles and 4 beta particles in a 10-stage process.

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. In thorium …isotopes, predominantly the very long-lived thorium-232 (1.40 × 10 10-year half-life), the parent of the thorium radioactive decay series. Other isotopes occur naturally in the uranium and actinium decay series, and thorium is present in all uranium ores.

This chain of consecutive alpha and beta decays begins with the decay of 232 Th to 228 Ra and terminates at 208 Pb. 2016-03-11 · Thorium-232 ( 232 Th) is present in significant amounts in the Earth's crust and is an alpha-emitting radionuclide, which decays to radium-228 ( 228 Ra), which is a beta emitter with a half-life of about six years; it emits no significant gamma radiation. The thorium- 232 radioactive decay series, beginning with _{90}^{232} \mathrm{Th} and ending with ^{208} \mathrm{Pb}, occurs in the following sequence: \alpha,… Enroll in one of our FREE online STEM bootcamps.
