目的对1例工业CT(加速器)机房建设项目作放射防护评价。方法按防护评价的要求,根据实际情况,对拟建机房项目的辐射源项进行分析,屏蔽防护预期效果进行计算,并对其安全防护管理,以及实际防护效果、辐射源安全等方面进行检测分析。结果加速器机房的放射防护设施的防护效果与安全设施符合国家有关规定的要求。结论工业CT因为设计思想的缘故,其X射线头与医用CT的球管在检测中会周向转动不同,只朝一个方向平移,其放射防护措施与工业加速器相似,常规工业加速器采用的放射防护措施足以进行有效防护。
Objective To evaluate the radiation protection of one case of industrial CT (accelerator) room construction project. Methods According to the requirements of protection evaluation, according to the actual situation, the radiation source item of the proposed engine room project is analyzed, the expected effect of shielding protection is calculated, and its safety protection and management, as well as the actual protection effect and radiation source safety are analyzed and tested . Results The protective effect and safety facilities of the radiological protection facilities in the accelerator room meet the requirements of relevant state regulations. Conclusion Because of the design thought, the industrial CT can rotate circumferentially in the detection of the X-ray head and the medical tube of CT, and it only translates in one direction. The radiation protection measures of industrial CT are similar to those of industrial accelerators. Radiation protection of conventional industrial accelerators The measures are sufficient for effective protection.
