Assessment of Radionuclides in Absorbed Dose, Selected Granite Quarry Sites within Ohimini and Gwer-East Local Government Areas of Benue Annual Effective Dose and State Nigeria. AASCIT Journal of Physics. Vol. 3, No. 6, 2017, pp. 56-61. Radiation Hazards Abstract The assessment of radionuclides in selected granite quarry sites in Ohimini and Gwer- East Local Government Areas of Benue State was carried out using a 76x76mm NaI (TI) Received: October 13, 2017 detector crystal optically coupled to a photomultiplier tube (PMT). The detector is Accepted: November 3, 2017 enclosed in a 6cm lead shield with cadmium and copper sheet and data acquisition was Published: December 26, 2017 done by Canberra Nuclear Products (Meastro) at Center for Energy Research Training, Ahmadu Bello University, Zaria. These sites include Anmuda, Awulema and Ikpayongo quarry sites with five (5) samples from each site making a total of fifteen (15) samples. The result of the assessment of radionuclides in granite samples includes Radium-226 (226 Ra), Thorium-232 (232 Th) and Potassium-40 (40 K).
