Natural Radioactivity in Drinking Water in Sudan (Khartoum Region)

Water usually contains several natural radionuclide radon, radium, uranium isotopes, etc. Their concentrations vary widely since they depend on the nature of the aquifer, ground water pH, etc. Aims in this research broad overview of the radioactivity in drinking water is presented, for limiting the presence of radioactivity in waters intended for human consumption, and draft of guidelines for the planning of campaigns to measure radioactivity in drinking water proposed by the Environmental Protection. This research it is contain nine water samples were analyzed for natural radioactive materials in drinking water in Sudan (Khartoum area). The concentration of radioactive element has been assessed for the water samples taken from different location in Sudan. The studies included of 226Ra+228Ra, 222Raand 234U+238U concentrations indifferent type of water samples, (mineral, Nile River, wells water). The experimental setup was based on the electronic radon detector RAD7 for radon concentration, spectrum gamma detector HPGe for radium and instrument of alpha spectrometry for uranium. The measurements were carried out with a special kit of accessory vessels (vials) RAD7 H2O, which allows one to identify the total Ra226and Ra228 activity concentration in small water samples of one Litter in the range going from less than 0.0pCi/L to greater than 37.9pCi/L, also the results of uranium concentration between the 0.21ppb and 9.8ppb and maximum of radon concentration179.0 pCi/L.
