本文报告了国际放射生态学联盟于2015年11月组织的共识研讨会的成果。研讨会聚集了一个由30名科学家组成的学术多元化小组,以考虑辐射对人口和生态系统的生态影响。受切尔诺贝利和福岛灾难意外污染环境的刺激,人们对制定环境辐射防护框架的兴趣日益浓厚。在各种实验室和现场环境中进行的科学研究提高了我们对电离辐射对环境的影响的认识。然而,这些研究的结果有时似乎相互矛盾,并且对于风险评估的含义存在分歧。因此,专题讨论会的讨论集中在可能导致对结果的不同解释的问题上,例如实验室方法与现场方法,有机体与种群和生态系统推理策略,慢性暴露条件下的剂量估算方法及其意义。与会的科学家们,从各个学科和研究领域,也超越了传统的放射生态学,成功地培养了一种理解差异的建设性精神。从讨论中,该小组已经达成了七项关于环境保护防辐射的共识声明,补充了一些建议。这些陈述中的每一个都是背景化和讨论的,以有助于未来研究的方向和整合,其结果应就辐射的生态影响达成更好的共识,并巩固有效的辐射环境保护的适当方法。
This paper reports the output of a
consensus symposium organized by the International Union of Radioecology in November 2015. The symposium gathered an academically diverse group of 30 scientists to consider the still debated ecological impact of radiation on populations and
ecosystems. Stimulated by the Chernobyl and Fukushima disasters\' accidental contamination of the environment, there is increasing interest in developing environmental radiation protection frameworks. Scientific research conducted in a variety of laboratory and field settings has improved our knowledge of the effects of ionizing radiation on the environment. However, the results from such studies sometimes appear contradictory and there is disagreement about the implications for risk assessment. The Symposium discussions therefore focused on issues that might lead to different interpretations of the results, such as laboratory versus field approaches, organism versus population and ecosystemic inference strategies, dose estimation approaches and their significance under chronic exposure conditions. The participating scientists, from across the spectrum of disciplines and research areas, extending also beyond the traditional radioecology community, successfully developed a constructive spirit directed at understanding discrepancies. From the discussions, the group has derived seven
consensus statements related to environmental protection against radiation, which are supplemented with some recommendations. Each of these statements is contextualized and discussed in view of contributing to the orientation and integration of future research, the results of which should yield better
consensus on the ecological impact of radiation and consolidate suitable approaches for efficient radiological protection of the environment.
