Estimation of Excess Lifetime Cancer Risk (ELCR) from Naturally Occuring Radioactive Materials in Mill Tailing Samples of Maiganga Mining Site, Gombe State, Nigeria

J. A. Rabiu, A. I. Olanrewaju & H. Dangoje · South Asian Research Journal of Natural Products · 2026

Aims: Mining activities have shown to give rise to so much waste (tailings) which may have poisonous elements and lethal to man and the entire ecosystem. Consequently, it affects his health negatively during and after production. This study estimated the excess lifetime cancer ri...
