摘要

日本核管理委员会(NRA)就2019年批准的修订后的测量和评估指南征求公众意见,其中包括关于如何处理测量和核素矢量中的不确定性的严格决定。为了解决关于许可不确定的问题,日本原子能学会以前的标准中已经确定了一种概率方法,并纳入了国际原子能机构(原子能机构)第67号安全报告。NRA对许可不确定性的新决定比概率方法严格10倍。在国际一级正在修订的原子能机构安全指南RS-G-1.7的框架内讨论了这个问题。关于清除不确定性的讨论引起了人们对其对全世界其他辐射防护条例的影响的严重关切。这是因为如果我们需要对清除的不确定性进行严格处理,那么对于超过10 μ Sv年的剂量,可能必须对其他放射防护标准进行相同或更严格的合格评定。辐射防护专家,包括监管机构、专业人员和操作人员,应该通过考虑制定辐射防护标准的背景科学基础,了解辐射防护标准的基本含义。

Trend of strengthening clearance regulation in Japan and concerns about its worldwide effects on regulations for natural and artificial radionuclides.

The Nuclear Regulation Authority (NRA) of Japan invited comments from the public on a revised guide on measurement and evaluation for clearance in 2019, which included a strict decision on how to treat uncertainties in the measurement and the nuclide vector. To resolve the issue on the uncertainty in clearance, a probabilistic approach had been established previously in the Atomic Energy Society of Japan Standard and incorporated into International Atomic Energy Agency (IAEA) Safety Report No. 67. NRA's new decision on the uncertainty in clearance was up to 10 times stricter than the probabilistic approach. This issue has been discussed at an international level in the framework of the ongoing revision of IAEA Safety Guide RS-G-1.7. This discussion on the uncertainty in clearance has raised serious concerns about its effects on other radiological protection regulations worldwide. This is because if we need strict treatment for the uncertainty in clearance, the same or even stricter treatment for conformity assessment may have to be applied to other radiological protection criteria for doses exceeding 10 µSv year-1. Radiological protection experts including regulators, professionals, and operators should be aware of the essential meaning of the radiological protection criteria by considering the background scientific basis on which they were established.

期刊介绍: The International Commission on Radiological Protection was founded in 1928 to advance for the public benefit the science of radiological protection. The ICRP provides recommendations and guidance on protection against the risks associated with ionising radiation, from artificial sources as widely used in medicine, general industry and nuclear enterprises, and from naturally occurring sources. These reports and recommendations are published six times each year on behalf of the ICRP as the journal Annals of the ICRP. Each issue provides in-depth coverage of a specific subject area.
