Radon concentration measurement in a groundwater in Al-Tuz, Salah Al-Din Governorate using nuclear track detector CN-85

Abstract

Abstract This work aims to determine the radon concentration in different samples of groundwater in Al- Tuz, Salah Alden. The concentrations of radon were studied in 52 samples for different regions using CN-85 nuclear track detector. The results show that the concentration of radon gas in groundwater were ranged between the lowest value (0.727 Bq/L) in the modern morning well sample (w44) and the highest value (4.001 Bq/L) in the west of the district of Tuz well sample (w47) with an average (1.747). The results were found to be below the allowed limit of radon concentrations 222Rn (11.1 Bq/L). The mean annual dose of drinking water was ranged between the lowest value (2.619μSv/y) in sample W44 and the highest value (14.45 μ Sv/y) in the sample W47 with an average (6.292 μ Sv/y). All annual doses of drinking water values in this work were lower than the allowed limit (22.024 μ Sv/y).
