Abstract

The radiation levels in mine wastes and soil of cassiterite mine sites from Rayfield, Gero, Sabongida Kanar, Kuru Jantar, Bisichi and Barkin Ladi, Plateau State, Nigeria had been assessed. Samples of mine wastes were collected from the aforementioned mine sites while soil samples were collected from farmlands in the vicinity of the mines. The annual effective doses recorded in all the soil and mine waste samples collected were above the 1mS/yr for general public limit set by the International Commission for Radiological Protection (ICRP). Inhabitants in close proximity to the mines should also be dissuaded as this can expose them to high concentrations of radiations. The present use of mine tailings for baking and frying as well as for plastering of houses should be discontinued as these could result in exposure to radiation from the Naturally Occurring Radioactive Materials (NORMs).
