Measurement of Radon Levels in the Groundwater of Al-Rusaifah City in Zarqa Governorate Using Liquid Scintillation Counter
Groundwater wells in Al- Rusaifah in central Jordan were investigated for radon (222Rn) levels during the winter season using a liquid scintillation counter (LSC). 222Rn was detected in eighteen groundwater samples from six different wells. The concentrations of radon varied from 151.9 to 253.1 Bq/L. The upper concentration limit of 222Rn for drinking water is 11 Bq/L based on the Jordanian Standards for Drinking Purposes. This indicates that 222Rn levels in all groundwater samples exceed the permissible threshold. The health impact assessment of 222Rn showed that for all samples, the total populationweighted average annual effective dose was 3.147mSv/y, which is greater than the maximum value of the general annual effective dose from radon of 0.1 mSv/y, according to the WHO and the European Council.
