Benue state (Health) Radiation

Radiation exposure level in some granite quarry sites in Ohimini and Gwer-East Local Government Areas of Benue State was carried out using radiation meter (radiation alert inspector). The research investigated only the exposure dose rate, the mean absorbed dose and the mean annual effective dose equivalent of the radiation. The investigation recorded a dose rate of 33.00-42.800 count per minute (CPM) with a background radiation of 23.00 (CPM), 31.200-42.200 count per minute with a background radiation of 18.00 (CPM), 36.00-51.00 count per minute with a background radiation of 20.00 (CPM) in Anmuda, Awulema and Ikpayongo quarry site respectively. The mean absorbed dose (Do) in Anmuda, Awulema and Ikpayongo are 12.3 nGy/h, 17.27 nGy/h and 18.87 nGy/h respectively and the corresponding mean Annual Effective Dose equivalent (AED) are 0.15 mSv/y, 0.21 mSv/y and 0.25 mSv/y which are below the recommended safe values. The investigated value falls within the global range of outdoor radiation exposure given by UNSCEAR.
