Abstract

Radioactivity found in underground water has become a serious issue of health concern across the globe in recent years. In this study gross alpha and beta radioactivity in package drinking water were analysed using Eurisys measures IN20 eight-channels-gas-filled proportional counter. Seven samples were collected from different package drinking water producing companies across Aliero metropolis, Kebbi state, North-western Nigeria using alpha and beta sampling procedure. The results obtained shows that, the range of alpha activity concentration in the analysed samples is 0.007 to 0.080Bq/L with a geometric mean of 0.041Bq/L which gives average yearly effective dose equivalent for gross alpha 0.011mSv/yr. Further results indicate that, the range of beta activity concentration in the samples ranges from 0.120 to 0.98Bq/L with a geometric mean of 2.66Bq/L giving average yearly effective dose equivalent for gross beta of 0.695mSv/yr. The findings of the research reveals that, the beta activity concentration in most of the samples is above the minimum level set by World Health Organization (WHO) and United States Environmental Protection Agency (USEPA) hence the water are not safe for drinking and other domestic activities.
