<![CDATA[Mining involves excavating soil with radioactive materials, which may enter the food chain and harm humans. This study evaluated the risks of exposure to ionizing radiation from radium-226, potassium-40, and thorium-232 in Udege Mbeki mining area of Nasarawa State, Nigeria. Twenty-one (21) soil samples were randomly collected in the mining site. The activity concentration of 226Ra, 232Th, and 40K in the samples ranged from 12.7462-430.8147 Bq/kg, 38.4147-725.4748 Bq/kg, and 22.3092-395.5596 Bq/kg respectively. The estimated effective dose in the Udege mined site soil samples was 19.7538-330.3428 mSvy-1, with an average of 148.8091 mSvy-1 in the dump, 67.1197 mSvy-1 in the farmland, and 121.4909 in the surface soil. These values exceed ICRP's recommended reference level of 1mSvy-1 for public exposure and 20 mSvy-1 for workers. Thus, the mine is hazardous for both the public and workers. It is recommended that the implementation of a routine monitoring be implemented on the radiation levels in the mined tailings on a periodic basis, so as to keep track of the rise and fall in the radioactivity levels. This is necessary for a sensitization scheme to be put in place in order to educate the inhabitants of the area on the need for self-protection from the hazards of ionizing radiation as well as educating the workers on the necessity to follow the right procedure and use the necessary protective gears.]]>
