The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks. 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 2011-05-16 · Thorium-232 undergoes radioactive decay until a stable isotope is reached. Write the reactions for the decay of Th-238.

The nuclear equation for the beta decay of cadmium is 113 and 48 which is the atomic number is right under 113 and the symbol which is Cd is between them. 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 .
