The purpose of the current study was to determine the radionuclides in ground water in Riyadh (Latitude 24.774N, longitude 46.738E) using High Pure Germanium (HPGe) gamma detector (GMX40POrtec). In addition, the drinking water bottles investigation was comparable to the groundwater used for other purposes by the resident in the area. The water sample analysis results show, the radioactivity concentration average of Uranium-238 (²³⁸U) is: 10.029 ± 3.013 mBq/L, for Radium-226 (²²⁶Ra): 2.224 ± 0.614 mBq/L, for Thorium-232 (²³²Th): 6.69 ± 1.664 mBq/L and for Potassium-40 (⁴⁰K): 55.983 ± 6.349 mBq/L. The radium equivalent (R_eq) assessment was found in the range of 10.021 mBq/L to 20.123 mBq/L, while the intern... view more»
