Determination uranium concentration in tap water by using SSNTD

Uranium and Radon concentration were created in water by the decay of naturally occurring radionuclide (238U,232Th) and their daughter (226Ra). The samples were collected from the different location in Al-Muthanna City south of Iraq. The Uranium and Radon concentration were determined through seal cup/passive method by utilizing the CR39 SSNTD. It was founded the concentration for Uranium and Radon between (0.065691 to 0.337838 µg/L), (0.00516 to 0.026539 Bq/L) respectively. The value of the dissolved radon (Cd) concentration in the collected samples varies from 0.1771 to 0.0344Bq·L-1 with an average of 0.0804 Bq·L-1, The value of the Annual Effective Dose (AED) concentration varies from 0.0969 to 0.0188 µSv·y-1 with an average of 0.04399µSv·y-1. The present results have displayed that the Uranium and radon concentrations in tap water samples are lower than the recommended limit 11.1Bq/L. The consumption of this tap water does not lead to any health risk to the population of Al-Muthanna governorate.
