Abstract
Twenty (20) samples of water from hand dug wells and boreholes in Bichi Local Government Area were selected using a stratified random sampling. Few drops of concentrated nitric acid were added to each one litre of the sampled water for preservation. The samples were then evaporated and counted for Gross Alpha using MPC 2000 model gas filled proportional counter. Results of alpha activities in water in the assessed area showed a range of 0.080Bq/L to 2.166 Bq/L with a geometric mean of 0.544 Bq/L. This value is slightly above the World Health Organization (WHO) recommended practical screening level of 0.5Bq/L for radioactivity in drinking water, but below the United States Environmental Protection Agency (USEPA) recommended practical screening level of 0.55 Bq/L for radioactivity in drinking water. Adequate discussions and appropriate recommendations are made for further research work in this field.
