Abstract

This study aims to assess radon-222 concentration levels in public ground water wells in Sana'a city, Yemen. Forty-three well water samples were collected from the study area. The alpha spectroscopy method was used to measure the samples using a RAD7 detector. The radon concentrations were in the range from 0.82 ± 0.38 Bq/L to 38.73 ± 2.98 Bq/L. A moderate correlation of radon levels with aquifer type was observed. Also, weak correlations of radon levels with electric conductivity, pH, and temperature, and no correlation with measured heavy metals were observed. Annual effective dose rates () were calculated and were found to be in the range from 0.006 to 0.283 mSv/y. Also, ion analysis of heavy metals was carried out. The analysis shows the maximum concentrations of copper, zinc, arsenic, and lead in groundwater samples were 0.5 mg/L, 0.58 mg/L, 0.7 mg/L, and 0.5 mg/L respectively.
