2016年西藏日喀则市医疗机构医用辐射防护现状调查分析

目的 了解西藏日喀则市医用辐射防护现状。方法 采用放射诊疗机构基本情况调查表进行现场调查并记录，根据放射卫生相关标准规范对所选取医疗机构的放射诊断设备进行性能质量控制检测和工作场所的放射防护检测，并对结果进行分析。结果 5家医疗卫生机构共检测设备13台，放射工作场所13个，合格率均为84.62%；其中DR合格率80%，CT合格率100%，影像增强透视机合格率为75%，不合格主要指标为DR的曝光时间指示偏离和影像增强器入射屏前空气比释动能率；个人防护用品平均配置率1.3件/台。结论 调查的5家医疗机构个人防护用品配置不足，工作人员防护意识缺乏；场所防护和设备性能检测均未严格根据相关标准规定执行。建议进一步加强放射诊疗设备管理与检测等相关工作。

Investigation and analysis of current status of medical radiation protection in medical institutions in Shigatse,Tibet, 2016

Objective To overall understand the status of medical radiation protection in Shigatse Prefecture, Tibet. Methods The questionnaire was conducted on the basis situation of medical institutions undergoing X-ray diagnosis.

Results Thirteen equipment and thirteen radiation workplace from five hospitals were monitored in this survey.The gross qualified rate was 86.62%. Among them, the qualified rates of DR, CT and image enhancement fluoroscopy machine were 80%,100% and 75%,respectively. The deviation of exposure time indicationin DR and the entrance air kerma rate of fluoroscopy machine were the main unqualified parameters. The personal protective article was averaged to be only 1.3 per set of device. Conclusion The personal protective articles were not enough in the five hospitals and the self-protection awareness of radiation was lacked. Monitoring of radiation workplaces and X-ray diagnostic equipment were not fully executed as required by the relevant standards. The management and examination must be enforced.
