摘要
本文根据监测方案对某核电站周边地区的环境γ辐射、大气、水、土壤、陆地动植物和海洋动植物及排放的放射性气体等进行辐射环境监测,经过实验分析可知,各个指标值都在本底范围内。通过γ外照射、气载放射性的内外照射和食入食物的内照射分别计算对人体的危害,其中气载放射性危害非常小,γ外照射和食物内照射引起的年有效剂量分别为0.127m Sv/a和0.115m Sv/a,都在国家管理限值内,即在正常运行工况下,核电站对周边辐射环境影响很小,核电站是安全可靠的。
According to the monitoring program, radiation environmental monitoring have been ran to power plant surrounding areas on environmental γ radiation, air, water, soil, land and marine animals and plants, and radioactive gas discharged by the power plant, etc. Every index value is in the range of background through experimental analysis. The paper separately calculates the damage on the human body caused by external irradiation byγ ray, both inside and outside of airborne radioactive exposure and ingestion of food irradiation. The airborne radiological hazards are very small, and the annual effective dose of external γ radiation was 0.127 m Sv / a and in food irradiation was 0.115 m Sv/a, both within the national administration limits, which means in normal operating conditions, nuclear radiation impact on the surrounding environment is very small, and nuclear power plants are safe and reliable.
