Environmental health risk assessment due toradionuclides and metal(loid)s for Igdir province inAnatolia, near the Metsamor nuclear power plant

Background: there have been growing concerns about environmentalpollution and public health issues associated with metal(loid)s andradionuclides. as a baseline for monitorisation, radioactivity and specificmetal(loid) levels have been measured to investigate the estimatedenvironmental health risks in igdir province at the turkish side of the border,in the vicinity of the metsamor nuclear power plant, an aging nuclear stationwithout primary containment structures. materials and methods:concentrations of radioactivity and accumulation of metal(loid)s in the regionwere measured and hazard quotient, hazard index, and the excess lifetimecancer risk vaues were calculated according to international methods andstandards. results: hazard quotient and index values were determined to belower than the permissible maximum levels. the average estimated excesscancer risk values for terrestrial and cosmic exposures due to radionuclideswere calculated as 1.8±0.9e-04 and 2.4±0.04e-04, respectively. the averageestimated excess cancer risk value for the radioactivity in water wasdetermined as 15.2±13.6e-05. the mean excess lifetime cancer risk valuesdue to metal(loid) exposure were as cr
