摘　　要：采用普查、分层抽样调查和典型调查相结合的方法调查了河南省“九五”期间（1996～2000年）医用电离辐射应用的基本现状和医疗照射频度；用热释光[LiF（Mg，Cu，P）]剂量计测量了10种常见X射线诊断中受检者体表的剂量；估算了X射线诊断检查所致公众的年集体有效剂量和年人均有效剂量。结果表明，全省X射线诊断的频度为136．95人次／千人口，放射治疗的频度为0．338人次／千人口，临床核医学诊断检查的频度为0．595人次／千人口；1998年X射线诊断所致全省居民年集体有效剂量为14690．60人·Sv，年人均有效剂量为0．158mSv。To investigate the general situation on medical use of ionizing radiation and frequency of medical exposure, a combination method of general survey, sampling survey and typical survey is used. Body surface dose of patients from ten kinds of common diagnostic X-ray procedures were surveyrd with LiF（Mg, Cu, P）. The annual collective effective dose equivalent and per capita collective effective dose equivalent of population from diagnostic X-ray procedures were estimated. The results indicated that frequency of X-ray examination was 136.95 examination per 1000 population, frequency of radiotherapy was 0. 338 examination per 1000 population, and frequency of clinical nuclear medicine was 0. 595 examination per 1000 population; The annual collective effective dose equivalent of the residents in Henan Province from X-ray examination in 1998 was 14 690.6 man·Sv,and average annual per capita effective dose equivalent was 0. 158 mSv.
