The success achieved to minimise the radiation exposure to staff to levels much below the prescribed dose limits encourages a similar approach in patient protection where dose limits do not exist but where reference levels are provided. A number of radiation injuries among patients have been reported, per capita dose is increasing and medical exposure has become the largest contributor to population dose. The International Atomic Energy Agency (IAEA) has supported a number of research projects, produced a wide range of guidance publications, conducted over 60 training courses in the past 5 y, produced for free dissemination training CDs on radiation protection and established a dedicated Web site on the radiological protection of patients (http://rpop.iaea.org). The number of countries that is currently receiving assistance in this field exceeds 80, as compared to about half a dozen 5 y ago. Significant results on patient dose management, demonstrating dose reduction of more than 30% while maintaining image quality, have been made available through IAEA projects.
在将工作人员的辐射暴露降至远低于规定剂量限值方面所取得的成功，促使人们在患者防护方面采取类似方法，尽管患者防护不存在剂量限值，但有参考水平。已报告了一些患者辐射损伤事件，人均剂量在增加，医疗照射已成为人群剂量的最大贡献者。国际原子能机构（IAEA）支持了多个研究项目，编写了大量指导出版物，在过去5年里举办了60多期培训班，制作了供免费传播的辐射防护培训光盘，并设立了一个关于患者放射防护的专门网站（http://rpop.iaea.org）。目前在这一领域接受援助的国家超过80个，而5年前约为6个左右。通过国际原子能机构的项目，在患者剂量管理方面取得了显著成果，即在保持图像质量的同时，剂量减少了30%以上。
