国际社会在达成共识方面取得了长足的进步,即自然发生的放射性材料和核遗留场址的补救和管理将受益于使用基于风险的决策框架。这样的框架应理想地整合风险评估和决策。本文提出的框架专门针对更广泛的社会经济和环境背景下的需求和期望,以及狭隘的人类健康环境。该框架作为国际原子能机构第二个辐射影响评估模型和数据计划的一部分进行了演示。三个案例研究,已经使用或可能使用这种综合方法,用于说明。第一个问题涉及萨斯喀彻温省北部比弗洛奇湖铀矿开采活动的补救,加拿大,让利益相关者(也称为“利益相关方”)参与进一步选择的决策过程。第二个案例研究表明,决策分析如何能够支持在兹罗夫斯基vrh选择铀矿石加工的废物处理的最佳选择,斯洛文尼亚,考虑到洪水时潜在的滑坡和废物在整个邻近山谷中的迁移。第三个案例研究介绍了Tessenderlo地区Kepkensberg污泥盆地的放射性安全评估过程和结果,比利时在处理附近温特贝克河修复材料之前和之后。它说明了此类评估如何与决策分析相结合,以支持与未来批准废物处置方案有关的监管决策。结果表明,正式的利益相关者参与决策分析为客观,健壮,和透明的决策,不仅适用于辐射保护区,而且适用于健康和环境影响受到关注的其他地区。还对今后的工作提出了一些建议。
The international community has come a long way in developing a consensus that the remediation and management of naturally occurring radioactive materials and nuclear legacy sites will benefit from the use of the framework for risk-informed decision-making. Such a framework should ideally integrate risk assessment and decision-making. The framework presented in this paper specifically addresses the needs and expectations in the wider socio-economic and environmental context, as well as a narrower human health context. The framework was demonstrated as part of the International Atomic Energy Agency\'s second Modelling and Data for Radiological Impact Assessments Programme. Three case studies, which have used or could use this integrative approach, are used for illustration. The first concerns remediation from uranium mining activities at Beaverlodge Lake in northern Saskatchewan, Canada, engaging stakeholders (also called \'interested parties\') in the decision-making process on further options. The second case study suggests how decision analysis could support the selection of the best option for waste disposal for uranium ore processing at Žirovski vrh, Slovenia, taking into account a potential landslide and migration of waste throughout the adjacent valley in the event of flooding. The third case study presents the process and results of radiological safety assessment of the Kepkensberg sludge basin in Tessenderlo area, Belgium both before and after the disposal of material from remediation of the nearby Winterbeek River. It illustrates how such assessments could interface with decision analysis for the purpose of supporting the regulatory decisions related to future approval of a waste disposal option. Results show that formal stakeholder engagement in decision analysis provides a strong contribution to objective, robust, and transparent decision-making not only for radiation protection area but also in others where health and environmental impacts are of concern. A number of recommendations for future work have also been made.
