Abstract
The assessment of the radiation hazard indices of solid minerals and sand in mining sites of Benue State, Nigeria was carried out using well calibrated radalert-50 and 100 meters and a Global Positioning System (Garmin 765). The sites investigated are Lessle (Barite), Gboko (Limestone), Owukpa (Coal) and Akuana (Salt) deposits fields. The mean background radiation ionization exposure rate of 0.019±0.004, 0.019±0.004, 0.014±0.002 and 0.023±0.005 mRh-1 were obtained respectively. The mean of absorbed dose rates estimated for the mining fields are 161.53, 169.40, 120.35 and 201.84 nGy/hr respectively. Estimated values of the annual effective dose equivalent (AEDE) ...
