摘要
根据2009年度秦山核电基地外围各居民点及附近海域环境样品中14C活度浓度监测数据,结合秦山核电基地外围农村居民生活及饮食习惯等资料,采用GB 18871—2002推荐的年龄别剂量系数,估算由空气和食物途径所致居民14C的年摄入量和年待积有效剂量。结果表明,关键居民组所受到的年待积有效剂量最大值为14.11μSv/a。
Based on the measurements of village and sea areas around the Qinshan annual intake of carbon - 14 caused by carbon- 14 concentration in samples collected from Xiajiawan nuclear power plant （abbreviated as NPP） base in 2009, the inhalation of air and ingestion of food were estimated with consideration to local living and dietary habits. Then, by using the age-dependent dose coefficient recommended by the national standard of GB 18871-2002, the annual committed effective dose of residents around the Qinshan NPP base were calculated. The result shows the 7-12 years old resident group from Xiajiawan village suffered the biggest annual commited effctive dose of 14.11 μSv/a.
