Abstract

The hazards of being over-exposed to ionizing radiation at various mining sites are of great concern to environmental scientists. This study aims to measure the activity concentrations of 40K, 238U, and 232Th radionuclides at various mining sites of Paago, Iseyin local Government, Oyo state, Southwestern Nigeria using a well calibrated HPGe detector. Twenty (20) soil samples were obtained, analyzed, and compared with the WHO recommended standard. The results obtained indicate that 40K, 238U, and 232Th values ranging from 58.40 to 950.41Bqkg-1, 5.57 to 24.22Bqkg-1, and 4.1 to 25.93Bqkg-1. The gamma absorbed dose rate in the soil samples ranged from 6.85nGyh-1 to 45.73nGyh-1, with mean absorbed dose rate lower than the WHO recommended average value of 59nGh-1. The annual effective dose rates in the air varied from 14.26 to 19.74μ Svyr-1 with an average value of 17.99 μSvy-1, while the highest and lowest values of radium equivalent in the soil were 113.68Bqkg-1 and 21.62Bqkg-1. These findings shows that the external and internal hazard indices obtained were less than unity and the means activity concentration of the three radionuclides was lower than the world average recommended value indicating that the study areas pose no significant radiological threat to the populaces, and the crops are safe for consumption.
