Thorium 232 decay

Thorium The only gaseous product in the thorium decay series is thoron, which has a very short half-life (56 s). It can be used to determine 220 Rn, and also its parent, 232 Th. Thorium is determined by comparison with a standard, but because of the short half-life of 220 Rn, decay correction must be made. Therefore 232 Th belongs to primordial nuclides. 232 Th decays via alpha decay into 228 Ra. 232 Th occasionally decays by spontaneous fission with very low probability of 1.1 x 10 -9 %. 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.

Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seeingt part of the spectrum. The following spectrum was recorded with a 3" NaI (Tl) detector with GS-1100-PRO and PRA 16.

(a) Alpha decay followed by beta emission We use thorium (in thorium oxide) to generate thoron. The sequence of decays is known as the Thorium-232 series and goes as follows: Note that a lesser branch at ThC by α decay to ThC (81 Tl 208), and then to lead-208 by β decay, has been omitted here. As Thorium-234 undergoes beta decay, a neutron becomes a proton.

Gunnars tankar och funderingar: July 2010

In the thorium-232 natural decay series, the thorium-232 initially undergoes alpha decay, the resulting daughter emits a beta particle, and the succeeding daughters emit a beta and an alpha particle in that order. Write four nuclear equations, one to represent each of the first four steps in the thorium-232 decay … The thorium-232 decay series begins with the emission of an alpha particle. If the daughter decays by beta emission, what is the resulting nuclide? Learn this topic by watching Radioactive Decay Concept Videos. All Chemistry Practice Problems Radioactive Decay Practice Problems. Q. At the head of the thorium series, for example, thorium-232 undergoes alpha decay to radium-228.

Therefore 232 Th belongs to primordial nuclides.

The symbols α and β indicate alpha and beta decay with the asterisk indicating if the radionuclide 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 Thorium-232 is one of the most stable radioactive elements with isotopes that have abundance in nature 3 times more than. Uranium.
