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 (90 Th) has seven naturally occurring isotopes but none are stable. One isotope, 232 Th, is relatively stable, with a half-life of 1.405×10 10 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe. 232 Th occasionally decays by spontaneous fission with very low probability of 1.1 x 10-9 %. 232 Th is a fertile isotope.

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 2020-10-27 In this work, gamma-ray spectroscopy based on semiconductor hyper pure germanium (HPGe) detector was used to evaluate the activity concentrations of the natural radionuclides (U-238 (Ra-226), Th-232 and K-40) and the fallout nuclide (Cs-137) for thirty samples of igneous and sedimentary rocks of Al-Atawilah (Al-Baha). The mean values of the activity concentrations of U-238 (Ra-226), Th-232, K interference between Th-232 and U-238 can decrease the resonance integral of the mixture by 3% or more from its correspondent value which supposes no interference. - compensating for the added complexity (and hence computing time) by adding an option to ENDF/B-VII TH-232 resonance total cross section 10-5 10-4 Energy (MeV) 101 102 103 104 Cross section (barns) total Th232 Decay Series Isotope half-life gamma energies (KeV) Th232: 1.405 x 10 10 years. 63.8 (0.267%) Ra228. 6.7 years-----Ac228.
