Natural Radioactivity of Igneous Rocks - Natural Radioactivity Measurements of Basalt Igneous Rocks at Sidakan District in Kurdistan Region-Iraq

Eight samples were collected from three different locations: Bardbizin Mountain, Kanishilana and Rubarok area around the Sidakan district in the northeastern of Kurdistan region, Iraq. The studied samples measured by using gamma-ray spectrometry, planar HPGe detector with an active area of 100 mm2, with an energy resolution of 0.520 keV at the 122 keV Co-57 line and NaI(Tl) Scintillation detector 2×2 inch, with an energy resolution of 11.3 % at the 662 keV Cs-137 line. Activity concentrations of each of U-238 (Ra-226), Th-232 (Ac-228), Cs-137, and K-40, radionuclides were measured; Along the study area the average value of radium equivalent activities, absorbed dose rate,Indoor and outdoor annual effective dose,The average value of external and internal hazard indices were calculated.
