摘要
目的掌握核电站运行前2010-2014年三门湾宁波毗邻区域居民恶性肿瘤发病数据资料和环境放射性本底数据。方法采用碘化钠闪烁体探测法监测放射性本底背景值,通过浙江省慢性病监测信息管理系统导出2010-2014年监测区域居民新发肿瘤病例资料,对肿瘤新发病例的总体发病情况、发病顺位、年龄别发病分布以及辐射敏感肿瘤的发病情况进行描述性分析。结果监测区域环境γ外照射剂量率背景值为(86.47±7.82)n Gy/h;2010-2014年三门湾宁波毗邻区域共报告恶性肿瘤新发病例6 270例,肿瘤标化发病率为207.97/10万,前5位肿瘤依次为肺癌(18.49%)、肝脏和肝内胆管肿瘤(10.52%)、胃癌(7.87%)、结直肠及肛门肿瘤(6.97%)和甲状腺癌(6.83%);而该区域辐射敏感肿瘤的标化发病率分别为3.56/10万(白血病)和14.95/10万(甲状腺癌)。结论研究结果客观展示了核电站宁波区域30 km范围内的环境放射性本底背景值和居民恶性肿瘤的发病情况,为核电运行后环境放射性监测数据和居民健康数据的前后对比和关联性分析提供参考。
Objective To obtain the baseline data of local residents＇ cancer incidence and environmental terrestri- al gamma-radiation dose around Sanmen Bay in Ningbo city from 2010 to 2014 before operation of Sanmen Nuclear Power Station. Methods The environmental radioactivity background values was monitored by adopting the Sodium iodide scintil- lator detection method and the relevant data on new tumor cases among local residents was collected from Zhejiang Chronic Diseases Surveillance Information Management System, and thena descriptive analysis was conducted on the overall inci- dence of new tumor cases, incidence sequence, incidence distribution by age, and radioactivity-sensitive tumors. Results The background value of the environmental terrestrial gamma-radiation dose in this area was 86. 47± 7.82 nGy/h and 6 270 new tumor cases were reported. The residents＇ tmnor standardized incidence rate was 207.97/100 000 and the top five tumors were lung cancer （ 18.49% ） , liver and intrahepatie bile duct cancer （ 10. 52% ） , gastric cancer （7.87%） , color- eetal and anal cancer （6. 97% ） and thyroid carcinoma （6. 83% ）. The standardized incidence rate of Leukemia and thy- roid carcinoma both belong to radioactivity-sensitive disease were 3.56/100 000 and 14. 95/100 000 respectively. Conclu- sions The research showed the original environmental radioactivity background values and the incidence of radioactivity- sensitive tumors among the local residents in the area adjacent to the Nuclear Power Station around Sanmen Bay in Ningbo city within a radius of 30 kilometers objectively, also laid a firm foundation for long-term environmental radioaetivity monito- ring and evaluating the residents＇ health condition. Furthermore, we can reference the result to conduct the comparative study and association analysis later.
