Abstract Objective To study the change of antioxygen level of those who are continuously exposed to light and chronic radiation.Methods 53 male inhabitants aged from 50-59 years are selected as the object of study,who are born and bred in Yangjiang high natural background radiation area .Additional male inhabitants of similar ages in the town of Hengpi,Enping are chosen as the contrast group.5ml of peripheral blood is separately drawn to determine the activity of superoxide dismutase and the content of malondialdehyde in the serum.Results In the serum of HBRA and CA groups,the activity of SOD is <65.9±38.5> and (50.2±26.2)μ/ml respectively,and the content of MDA is (4.5±2.0)nmol/ml and (6.5±2.6)nmol/ml respectively.Compared with CA group,the activity of HBRA group is high.but its content of MDA is low.These differences are statistically significant (P<0.05).Conclusion Natural high background radiation could have an effect on the antioxidation indexes such as SOD and MDA.
