Determination of Radon Radiation Concentration in Groundwater for Some Wells of Baghdad City

Abstract

Abstract The Radon level was measured in (17) groundwater samples collected from Baghdad city/ Iraq and two samples from Tigris and Dyala River. The measurements were performed by RAD7 an electronic radon detector manufactured by Durridge Company Inc. The concentrations of radon (226Ra) ranged from 0.3 to 2 (Bq/L). Radon concentrations from all the villages/towns were well below the was lower than WHO and EPA standard limits recommended by USEPA, UNSCEAR, EU Council and WHO. The total annual effective doses ranges from 1.64to 10.95 μSv.y-1 were less than 0.1mSv.y-1 which Recommended by the World Health Organization (WHO). The study also examined the relationship between the total dissolved solids (TDS) and the concentration of Radon-222 and it shows the absence of any linear relationship between the variables and concentrations Radon.
