Thorium is an element that occurs naturally in the earth's crust. The only naturally occurring isotope of thorium is 232 Th and it is unstable and radioactive. 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.
