Determination of radiation hazard indices (Annual Gonadal Dose Equivalent) in water samples in the vicinity of mining site in Minna, Niger State, Nigeria

Abstract

The gross alpha and beta radionuclide activity of source of water from mining site in Minna, Niger state has been carried out. Eleven water samples were collected from the farming, residential/commercial, and industrial zones in the community and were analyzed using the protean instrument corporation (PIC) MPC 2000DP, single channel proportional counters. Annual Gonadal Dose Equivalent (AGDE) was determined. AGDE _{α and β} 20.254399/3.088977mSv/y. This shows that the calculated values of alpha in BHL3 are above the accepted value for ICRP. Moreover, the calculated values of beta in BHL1 are above the accepted value for ICRP. It can be observed that all the remaining values for alpha and beta are below the ICRP values of 0.5Bq/L for alpha and 1Bq/L for beta.
