|
|
| The interaction of radiation with matter, ether from external (i.e. external sources) or from internal pollution of the body by toxic substances, can pose biological hazard which may show the clinical symptoms later. This study aimed at assessing the Effects of Radiation Exposure to Human Sensitive Organs due to quarry mining in Kokona, Nasarawa and Toto of Nasarawa State Nigeria. Finding of this study have revealed that the mean annual effective dose rate for Kokona, Nasarawa and Toto are 0.0274, 0.0166 and 0.0227 mSv/y respectively. The mean excess lifetime cancer risk (ELCR) for Kokona, Nasarawa and Toto are 0.0960 × 10-3, 0.058 × 10-3 and 0.0795 × 10-3. The mean Effective Dose Rate to Organs (Dorgan), for the lungs, ovaries, bone marrow, testes, kidney, liver and whole body in Kokona, Nasarawa and Toto are 0.0176, 0.0107 and 0.0145, 0.0159, 0.0097 and 0.0132, 0.0190, 0.0115 and 0.0157, 0.0225, 0.0136 and 0.0186, 0.017, 0.0103 and 0.0141, 0.0126, 0.0077 and 0.0105, and 0.0186, 0.0113 and 0.0155 mSv/yr respectively. It can be concluded that the background radiation in different quarry mining sites of Kokona, Nasarawa and Toto 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. Also, it is 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. |
