Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seeingt part of the spectrum. 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. In fissile material the fertile materials uranium-238 and thorium-232, respectively. A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor.

2021-04-11 The activity concentrations of 232 Th range from 4.06 in sample BRY12 to 125.86 Bq kg 21 in sample BRY1. Finally, the activity concentrations of 40 K range from 31.3 in BRY12 to 2222.3 Bq kg 21 in BRY2.

Th), which are insufficient to initiate a nuclear chain reaction. Additional fissile material or another neutron source is necessary to initiate the fuel cycle. In a thorium-fuelled reactor, 232 Th absorbs neutrons to produce 233 U. This parallels the process in uranium breeder reactors whereby fertile 238 U absorbs neutrons to form fissile 239 Pu
