This research work tends to uncover the effect of exposure to radiation on human organs as a result of quarry mining taking place in Keffi and Karu of Nasarawa State using Inspector Alert Nuclear Radiation Monitor. The results showed that, the mean effective dose and excess lifetime cancer risk (ELCR) in Keffi and Karu are found to be 0.03372 and 0.02844 mSv/y for effective dose and 0.04956 × 10-3 and 0.09954 × 10-3 for excess lifetime cancer risk respectively. The mean Effective Dose to Organs (Dorgan), for the lungs, ovaries, bone marrow, testes, kidney, liver and whole body in Keffi and Karu are found to be 0.01215 and 0.01820, 0.01101 and 0.01650, 0.01310 and 0.01962, 0.01556 and 0.02332, 0.01177 and 0.01763, 0.00873 and 0.01308, and 0.01290 and 0.01934 mSv/y respectively. From the findings presented, it can be concluded that the radiation in different mining sites of Keffi and Karu of Nasarawa State is not an issue of health concern except on seventy years of exposure. It is therefore, advised that, government should stop the illegal mining and introduce mechanize mining for easy control of the health effects. It is also recommended that water and soil sample be taking for elemental analysis to ascertain the effect of the mining activity in these areas through ingestion, since it has no much effects on the populace of the area through inhalation according to this research.
