X射线技术的应用与发展,给医学诊断与治疗带来了很大的方便,但不可低估它对非受照者及公众的危害。为保障公众的健康与安全保护环境,对X线外环境照射量率进行调查。1 内容与方法 全市26(其中市直4、乡镇19、个体3)个单位X线工作人员操作位与外环境机房门口,采用WF—912型X射线巡测仪进行照射量率定点监测。2 调查结果 工作人员操作位全部符合放射卫生防护标准,机房门口大多数是超标。4个市直单位2个合标2个超标,照射量率最高300 μGy/h,超标9倍。19个乡镇单位1个合标18个超标,照射量率最高为10 000 μGy/h,超标332.3倍。3家个体单位全都
The application and development of X-ray technology has brought great convenience to medical diagnosis and treatment, but it can not be underestimated its harm to non-exposed people and the public. In order to protect the public’s health and safety of the environment, X-ray exposure to the environment outside the rate of investigation. 1 Content and Methods The X-ray staff of Xinyu 26 (including Shizheng 4, Hexiang 19, and Xce 3) operating positions and the door of the outside environment machine room were monitored by using the WF-912 X-ray detector. 2 Survey Results All staff operating position in line with radiation protection standards, most of the engine room door is excessive. 4 units directly under the city 2 2 standard mark exceeded the maximum exposure rate of 300 μGy / h, exceeding the 9 times. 19 township units a standard 18 exceeded, the highest exposure rate of 10 000 μGy / h, exceeding the standard 332.3 times. 3 individual units all
