Radiological risk assessment of naturally occurring radionuclides in water from the Rafin Gora gold mining community in Nigeria
This study reveals that water sources in Nigeria's Rafin Gora gold mining community contain elevated levels of naturally occurring radionuclides (226Ra, 228Ra, and 40K) that significantly exceed WHO guidelines, posing serious chronic radiological health risks including high annual effective doses and cancer risks that necessitate immediate regulatory intervention and water treatment.
