生态资源的辐射防护目标侧重于人口、社区和生态系统层面的生态结构和功能。目前对非人类生物群辐射安全的处理办法依赖于生物体一级的终点，因此与国际机构所述的总体保护目标不一致。暴露于压力因素可引发生态系统结构和功能的非线性变化，而这些变化无法从对单个生物体的影响中预测。从生态科学，我们知道，重要的互动动态与这些新兴的属性决定了人类社会所依赖的生态系统中的商品和服务的流动。国际放射生态学联合会（IUR）的前一个工作组提出了将生态系统方法添加到可用于管理辐射安全的工具套件中的理由。在本文中，我们总结了生态系统方法的论点，并确定了与开发和实施实用的生态系统方法有关的下一步措施和挑战，以补充目前用于辐射安全的生物体级终点。(C)2014爱思唯尔有限公司版权所有。
Radiation protection goals for ecological resources are focussed on ecological structures and functions at population-, community-, and ecosystem-levels. The current approach to radiation safety for non-human biota relies on organism-level endpoints, and as such is not aligned with the stated overarching protection goals of international agencies. Exposure to stressors can trigger non-linear changes in ecosystem structure and function that cannot be predicted from effects on individual organisms. From the ecological sciences, we know that important interactive dynamics related to such emergent properties determine the flows of goods and services in ecological systems that human societies rely upon. A previous Task Group of the IUR (International Union of Radioecology) has presented the rationale for adding an Ecosystem Approach to the suite of tools available to manage radiation safety. In this paper, we summarize the arguments for an Ecosystem Approach and identify next steps and challenges ahead pertaining to developing and implementing a practical Ecosystem Approach to complement organism-level endpoints currently used in radiation safety.
