Radiation exposures from mining and mineral processing 

industries can lead to high incidence of disease conditions like 

nausea, lung cancer, sterility, fatigue, and diarrhoea among mine

workers. The concentration of primodial radionuclides (238U, 

232Th and 40K) in some selected mining sites in Nasarawa State, 

Nigeria, was examined in this study. Soil and rock samples from 

eight different mining sites were collected and analyzed for 

radionuclides activity concentration by gamma ray 

spectrometery using a scintillator detector NaI (Tl), while soil 

physical and chemical parameters were analyzed using standard 

methods. Data obtained was analyzed through descriptive 

statistics using SPSS statistical package. The results obtained for 

the annual gonadal dose equivalent, absorbed dose rate, outdoor 

annual effective dose equivalent, indoor annual effective dose 

equivalent and excess lifetime cancer risk were found to be 

above the globally permissible limits, for both rock and soil 

samples.
