Aim: The study was aimed at assessing the radiation levels and radiological health hazards in Keffi Dumpsite, Nasarawa State, Nigeria using Inspector Alert Nuclear Radiation Monitor.
Method and Materials: The inspector Alert Nuclear Radiation Monitor with the serial number 35440, made in USA by ion spectra (International Med. Com. Inc) using alkaline battery 0f 9.0volts, a scientific calculator, personal computer (laptop), pen and exercise book were used. Radiation was measured by using radiation monitor with in-build Geiger Muller tube operating in the Dose Rate mode to determine the background ionizing radiation level from selected dumpsites of Keffi.
Results: The mean annual effective dose rate for Keffi dumpsites were 0.19 mSv/y. The finding finally revealed that the mean Dorgan values for the lungs, ovaries, bone marrow, testes, kidney, liver and whole body for Keffi dumpsites were 0.122, 0.110, 0.131, 0.156, 0.118, 0.087 and 0.129 mSv/y respectively.Conclusion: It was concluded that background radiation in Keffi dumpsites is not an issue of health concern except when accumulated over long period of time which may cause cancer to the indoor members on approximately seventy years of exposure.
