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 master the protective situation of interventional radiological workplace in a district hospital for 10 years and control the radiation hazard. Methods: Based on the interventional radiology projects of 19 hospitals in the area, the reports of radiation protection supervision and inspection of 2005, 2007, 2009, 2011, 2013 and 2015 were consulted. According to the relevant national radiological protection regulations and standards, And place the corresponding key indicators of protection for statistical analysis. Results: The number of interventional radiology equipment has been increasing in 10 years, and the protective facilities have been gradually improved. Bedside see-through protection zone testing air radiant air kerma rate, the radiation dose equivalent rate around the engine room, engine room status indicator, ionizing radiation warning signs, radiological staff bedside protection facilities and protective equipment with the situation and other indicators of protection The passing rate declines year by year, radiological protection is becoming more and more standardized. Conclusions: The air kerma rate on the testing plane of the bedside protection zone is directly related to the degree of perfection of the protection facilities and the conditions of fluoroscopy used. Supervision and monitoring of radiological protection is also strengthened, and the facilities for protective facilities involved in radioactive interventions are well established and fully utilized The comprehensive protection of radiology is of great significance for interventional radiological protection.
