ABSTRACT The gross alpha and beta radioactivity pollution of main water supplies in Dutsinma metropolis were measured using proportional gas counter. The results show that the gross alpha radioactivity in water samples is lower than the maximum contaminant level of 0.1Bq/L set by World Health Organization (WHO). The measured alpha activities have a minimum of 0.001±0.0.003 and the maximum of 0.146±0.034 Bq/L with mean of 0.029±0.002 Bq/L. The gross beta radioactivity in water samples is h...
