Assessment of Radon Concentration in Underground Well Water from Selected Parts of Kaduna Metropolis

Abstract

Underground well water samples from selected areas in Kaduna metropolis were collected and analysed in order to ascertain the concentration of ²²²Rn. The analysis took place during the dry season when the weather was fairly stable and the community depended solely on ground water as their major water source for domestic use with a well calibrated a liquid scintillation counter situated at the Center for Energy Research and Training (CERT), Ahmadu Bello University, Zaria- Nigeria utilized for the measurements. The analysis results revealed and average concentration of 10.69 ± 0.39 Bq/L which is within the maximum concentration limit of 11.1 Bq/L and world average value of 10 Bq/L for drinking water.
