介入放射学是20世纪60年代兴起,并在20世纪70年代逐步应用于临床诊断和治疗的。介入放射是在X射线等影像导向监视下进行的插管操作或穿刺技术,从事介入放射工作的大多数是内科、泌尿科、肿瘤科的医务人员,他们缺乏放射防护知识。同时介入放射操作在床边进行,工作人员长时间暴露于X射线下,防护困难,会受到较大剂量照射。介入放射工作人员受照剂量和对健康的影响已引起广泛关注[1],UNSCEAR 2000年向联合国大会提交的报告中指出,介入放射操作使工作人员和患者受到很大剂量的照射[2]。介入放射工作人员的健康监护问题应受到足够的重视。 相似文献

目的 评价核设施在正常运行50年后对周围人群的健康影响.方法 调查甘肃某矿区周围30 km范围内居民2004-2008年人口资料、全部实体癌和白血病的死亡率.结果 调查地区居民2004-2008年全癌死亡率和标化死亡率分别为95.51/105和93.56/105,白血病死亡率和标化死亡率分别为2.44/105和2.22/105.对照区2004--2008年间恶性肿瘤死亡率和标化死亡率分别为106.88/105和89.31/105,白血病仅死亡1例,死亡率为3.56/105.结论 甘肃某矿区运行50年后,周围居民的恶性肿瘤和白血病死亡率未见增加,该矿区的生产和运行未对周围居民健康造成不良影响.Abstract: Objective To evaluate the cancer risk among the inhabitants around a certain nuclear facility of Gansu Province after operation for nearly 50 years.Methods Specially developed forms were filled by countryside doctors in the villages 30 km on the leeward or at the lower reaches of Yumen City,Gansu Province where a nuclear facility had operated for nearly 50 years,to register the relevant data of those who died of solid cancer and leukemia during the period from 1 January 2004 to 31 December 2008 based on the relevant data and household survey.A town 90 km away from the nuclear facility with 4181 people were regarded as control area.Results The crude mortality and standardized mortality rate(SMR) of cancer were 95.51×10-5 and 93.56×10-5.respectively.The crude mortality and SMR of leukemia were 2.44×10-05 and 2.22×10-05, respectively.and the crude mortality and SMR of cancer were 106.88×10-05, and 89.31×10-5, respectively.The crude mortality and SMR of leukemia were 2.44×10-05 and 2.22×10-5, respectively in the investigated area,and the crude mortality of leukemia was 3.56×10-5 (only one leukemia cage died)in the control area in the same time.The cancer and leukemia mortality rates of the investigated area were similar to those of control area.Conclusions Nuclear facility does not significantly increase the cancer mortality among the residents living nearby. 相似文献
