[Abstract] To make clear the orientation and propose suggestions for radiological protection for the future, this paper studied the situation of radiation protection of medical exposure, by virtue of the conclusion and analysis of data at home and abroad and the authors’ long-term observation during work. Radiation protection workers will do research and try to make breakthrough on indication of medical exposure, does limit of medical exposure employees, reduction of influence on public exposure, dose assessment of medical exposure, notification of medical exposure, and training of radiation management staff for the future.
[Key words] medical exposure, radiological protection
前言
电离辐射的和平应用,当数其在医学领域的应用历史最久、普及最广、影响最大。与其他先进技术一样,电离辐射的应用在给人类带来巨大利益的同时,也不可避免地会带来某种程度的负面影响。因此,自放射线诞生之日起一百多年来,电离辐射的应用,始终伴随着防止与减小辐射危害的放射防护理论和技术的研究与进步,相关法律、法规与技术标准的不断完善。时至今日,放射防护仍然是从电离辐射医疗应用现场所提出的最迫切的需要。
电离辐射在现代医学领域中,已发展为相对独立的X射线诊断学、核医学和放射肿瘤学三大现代医学学科。这些学科在疾病的预防与诊断治疗中发挥了独特作用,已成为现代医学不可缺
