Assessment of potential risk of cancer due to natural gamma dose rate around Harduaganj Thermal Power Station, Aligarh, U. P., India

This study assesses the health implications near the Harduaganj Thermal Power Station (HTPS), Aligarh, by measuring internal and external ambient gamma dose rates. The Annual effective doses varies for internal gamma radiation as 1.11 ± 0.14 m Svy⁻¹, for external gamma radiation as 0.19 ± 0.02 m Svy⁻¹, and gives a total gamma radiation as 1.31 ± 0.15 m Svy⁻¹, surpassing UNSCEAR and ICRP limits. The computed reduction coefficients exhibit a range from 1.11 to 2.13. The Excess Lifetime Cancer Risk (ELCR) metric estimates a range from 4.41 × 10⁻³ to 7.44 × 10⁻³. Furthermore, the investigation extends to the estimation of organ-specific doses received by individuals.
