Seventy-five years after the Hanford Site was initially created as the primary plutonium production site for atomic weapons development under the Manhattan Project, the American Nuclear Society and the Health Physics Society are sponsoring a conference from 30 September through 3 October 2018, in Pasco, Washington, titled "Applicability of Radiation Response Models to Low Dose Protection Standards." The goal of this conference is to use current scientific data to update the approach to regulating low-level radiation doses; i.e., to answer a quintessential question of radiation protection-how to best develop radiation protection standards that protect human populations against detrimental effects while allowing the beneficial uses of radiation and radioactive materials. Previous conferences (e.g., "Wingspread Conference," "Arlie Conference") have attempted to address this question; but now, almost 20 y later, the key issues, goals, conclusions, and recommendations of those two conferences remain and are as relevant as they were then. Despite the best efforts of the conference participants and increased knowledge and understanding of the science underlying radiation effects in human populations, the bases of current radiation protection standards have evolved little. This 2018 conference seeks to provide a basis and path forward for evolving radiation protection standards to be more reflective of current knowledge and understanding of low dose response models.
汉福德基地最初作为曼哈顿计划下原子弹开发的主要钚生产基地创建75年后,美国核学会和健康物理学会将于2018年9月30日至10月3日在华盛顿州帕斯科主办一场名为“辐射响应模型对低剂量防护标准的适用性”的会议。本次会议的目标是利用当前的科学数据更新低水平辐射剂量的监管方法;也就是说,回答辐射防护的一个基本问题——如何最好地制定辐射防护标准,既能保护人群免受有害影响,又能允许辐射和放射性物质的有益利用。此前的会议(如“温斯普雷德会议”“阿利会议”)曾试图解决这个问题;但现在,近20年后,这两次会议的关键问题、目标、结论和建议仍然存在,且与当时一样相关。尽管会议参与者付出了最大努力,并且人们对人群辐射效应背后的科学知识有了更多了解,但当前辐射防护标准的基础几乎没有变化。2018年的这次会议旨在为发展辐射防护标准提供一个基础和前进方向,使其更能反映当前对低剂量响应模型的认识和理解。
