目的了解某职防院、某民营健康体检机构流动体检车车载X射线机机房放射防护和车载X射线机的影像质量情况,对体检车车载X射线机及机房进行检测,并对结果进行分析评价。方法按照国家相关标准对车载X射线机性能及场所的放射防护进行检测。结果两体检机构车载X射线机的影像质量及机房的放射防护均符合国家标准,其中民营健康体检机构车载X射线机机房有射线漏出,且呈现逐年升高趋势。结论一方面需设置临时控制区,把公众照射将至最低;另一方面,应加强监管,提高民营机构对放射防护的意识。
Objective To understand the radiological protection of mobile X-ray machine room and mobile X-ray machine image quality in a vocational hospital and a private health examination center, to test the car X-ray machine and computer room of the medical examination car, and to analyze and evaluate the results . Methods According to the relevant national standards, the performance of X-ray machine and the radiological protection of the site were tested. Results The image quality of two X-ray medical institutions and the radiological protection of the engine room accorded with the national standards. Among them, the X-ray machine room of the private health examination body leaked out and presented an upward trend year by year. Conclusions On the one hand, temporary control areas need to be set up to minimize public exposure; on the other hand, supervision should be stepped up to raise the awareness of private institutions on radiation protection.
