1.4×1010 y, Spin 0 Parity 1. Show Decay Modes · Show Ultimate Decay Products. Atomic Weight, 232.038055325. Whereas thorium has only one isotope with a very long half-life (Th-232, uranium has two. (U-238 and U-235), giving rise to one decay series for Th and two for Thorium-232 decay chain. This is what thorium does naturally.

For irradiated thorium, the real concern lies in separating protactinium from uranium, which may already have significant levels of uranium 232. Production of protactinium 232 ceases as soon as protactinium is removed from the neutron flux, but protactinium 232 and 233 continue to decay to uranium 232 …

2 Using an emanation electroscope, we observe the radioactive decay of thoron (separated from all its parent substances) by the progressive decrease of ionization in the air around the thoron. How it works: We use thorium (in thorium oxide) to generate thoron. The sequence of decays is known as the Thorium-232 series and goes as follows:

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. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days. Thorium 232. 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.

More than 99% of natural thorium exists in the form of thorium-232. It breaks down into two parts-a small part called "alpha" radiation and a large part called the decay product.
