A number of tools and approaches have been developed recently to allow assessments of the environmental impact of radiation on wildlife to be undertaken. The International Commission on Radiological Protection (ICRP) has stated an intention to provide a more inclusive protection framework for humans and the environment. Using scenarios, which are loosely based on real or predicted discharge data, we investigate how radiological assessments of humans and wildlife can be integrated with special consideration given to the recent outputs of the ICRP. We highlight how assumptions about the location of the exposed population of humans and wildlife, and the selection of appropriate benchmarks for determining potential risks can influence the outcome of the assessments. A number of issues associated with the transfer component and numeric benchmarks were identified, which need to be addressed in order to fully integrate the assessment approaches. A particular issue was the lack of comparable benchmark values for humans and wildlife. In part this may be addressed via the ICRP's recommended derived consideration reference levels for their 12 Reference Animals and Plants.
最近已经开发了一些工具和方法，以便能够对辐射对野生动物的环境影响进行评估。国际放射防护委员会（ICRP）已表示有意为人类和环境提供一个更具包容性的保护框架。我们使用基于实际或预测排放数据的情景，研究如何将人类和野生动物的放射学评估与对ICRP近期成果的特别考虑相结合。我们强调关于人类和野生动物受暴露群体的位置假设，以及选择用于确定潜在风险的适当基准如何能够影响评估结果。确定了一些与转移部分和数值基准相关的问题，为了全面整合评估方法，需要解决这些问题。一个特别的问题是缺乏人类和野生动物可比的基准值。部分可以通过ICRP为其12种参考动植物推荐的导出考虑参考水平来解决。
