某地区19所医院介入放射工作场所防护状况调查分析

Investigation and analysis on the radiation protection of interventional radiology working place about 19 hospitals in one District

目的:掌握某地区医院10年间介入放射工作场所防护状况,控制辐射危害。方法:以该地区19所医院介入放射学项目为研究对象,查阅2005年、2007年、2009年、2011年、2013年和2015年的放射防护监督检测报告,依据国家相关放射防护法规标准,对与场所相应的关键性防护指标进行统计分析。结果:10年间介入放射学设备数量不断增加,防护设施日渐改善。床旁透视防护区测试平面上的辐射空气比释动能率、机房周围辐射剂量当量率、机房工作状态指示灯、电离辐射警示标志、放射工作人员床旁防护设施和防护用品配备情况等防护指标不合格率逐年下降,放射防护日趋规范化。结论:床旁透视防护区测试平面上的空气比释动能率与防护设施的完善程度、使用的透视条件有直接的关系;加强放射防护监督监测、完善介入放射工作场所防护设施配备和充分利用介入放射学的综合防护对介入放射学防护有重要意义。

Objective:To investigate the radiation protection status of interventional radiology working place about 19 hospitals in one district among 10 years and control the radiation hazard.Methods:According to the national related radiation protection standards,and consulting the radiation protection test report of 2005,2007,2009,2011,2013 and 2015,the interventional radiology working places of 19 hospitals in one district were selected as the survey object,and the key indexes about the radiation protection were statisticsed and analysized.Results:The number of the interventional radiology equipments incereased continually and radiation protection standardized among 10 years.The unqualified percent of the radiation protection indexes were dropping year by year which included bedside radiation protection test plane of the air kerma rate,working status indicator,ionizing radiation warning signs as well as protective equipment configurations and the protection facilities.The radiation protection work of the hospitals are normalizing.Conclusion:The air kerma rate in bedside X-ray protection zone surface is related with the application of the radiation protection facility and fluoroscopy condition;It is impossible to interventional radiology protection by strengthening the radiation protection supervision and monitoring,perfecting the radiation protection facility and making full use of the comprehensive protection.
