上海市奉贤区医疗机构放射防护监督抽检结果分析

Analysis of Surveillance on Radiation Protection from Medical Institutions in Shanghai Fengxian District

目的了解医疗机构放射防护现状,为加强放射防护工作的监督管理提供科学依据,更好地保障放射诊疗工作人员、患者和公众的健康权益。方法对抽取的上海市奉贤区20家医疗机构进行放射防护现状调查,并采用即时测量法对医用X射线诊断机房进行X射线剂量率检测。结果本次抽检的20家医疗机构均开展介入放射学诊疗和常规X射线影像诊断,各医疗机构的放射防护监督抽检结果整体情况较好。共抽检35间机房计1318个检测点,其中合格点数1311个,合格率99.5%。结论抽检的20家医疗机构放射防护情况较好,但部分X射线诊断机房的防护设施老化造成X射线剂量率超标,需对放射诊疗机房定期开展检测和屏蔽设施维护。

Objective To understand the status of radiation protection of medical institutions,in order to provide scientific basis for the supervision and management of radiation protection,and to protect the health rights and interests of the radiation medical staff,patient and the public＇s. Methods Selective inspection data of radiation protection from 20 medical institutions in Shanghai Fengxian district were collected and analyzed. The X- ray dose rate was detected by means of real- time measuring method for medical diagnostic X- ray room. Results The sampling 20 medical institutions are in interventional radiology diagnosis and treatment and conventional X- ray imaging diagnosis. The surveillance result of radiation protection of medical institutions was gerally good. A total of 1318 sampling points from 35 medical X- ray diagnostic rooms were inspected,1311 points were qualified and the qualified rates were 99. 5%. Conclusion The radiation protection of the sampling 20 medical institutions in Shanghai Fengxian district is currently at a high level. But the dose rate in the part of X- ray diagnostic room is over the standard limit due to the aging of protective facilities. Regular supervision and inspection,shielding facilities maintenance is necessary for radiation protection.
