摘　　要：目的调查某核设施厂区周围居民1997-2007年白血病发病率，并分析其流行趋势，为核设施正常运行或核事故致公众健康影响评价提供基础数据。方法采用回顾性调查方法，以该设施厂区为中心，将周围半径10km范围划定为调查区，调查区内至少居住6个月及以上的常住人口列为调查对象，收集人口学资料，到各级医院搜集白血病诊断资料。结果调查区1997—2007年共累计观察9409200人·年，新发白血病643例，粗发病率为2．51×10^-5，标化发病率2．53×10^-5，发病率略低于该核设施所在市的同期白血病发病率水平。这11年期间，未见白血病发病率随时间而改变。结论本次调查未发现该核设施周围居民白血病发病率增加。Objective To investigate the leukemia incidence among residents in the vicinity area of a nuclear installation. Methods The data were collected by the retrospective survey. Diagnosis is based on the medical records in all the relevant hospitals. The study area was those residential areas within 10 km of radium surrounding the installation. All residents who had lived in the study area for six months and over were recruited into the study group. Results The survey ascertained 643 newly diagnosed leukemia cases in the study area during 1997 to 2007. The crude rate was 2. 51/100,000, and its standardized rate to national population structure was 2. 53/100,000. The incidence rate in the study area was slightly lower than that in the whole city. No increase trend was detected during the period. Conclusions No significant difference of the leukemia incidence rate was found between the vicinity area of the nuclear installation and the whole city.
