This article presents the results of a workshop held in Stirling, Scotland in June 2018, called to examine critically the effects of low-dose ionising radiation on the ecosphere. The meeting brought together participants from the fields of low- and high-dose radiobiology and those working in radioecology to discuss the effects that low doses of radiation have on non-human biota. In particular, the shape of the low-dose response relationship and the extent to which the effects of low-dose and chronic exposure may be predicted from high dose rate exposures were discussed. It was concluded that high dose effects were not predictive of low dose effects. It followed that the tools presently available were deemed insufficient to reliably predict risk of low dose exposures in ecosystems. The workshop participants agreed on three major recommendations for a path forward. First, as treating radiation as a single or unique stressor was considered insufficient, the development of a multidisciplinary approach is suggested to address key concerns about multiple stressors in the ecosphere. Second, agreed definitions are needed to deal with the multiplicity of factors determining outcome to low dose exposures as a term can have different meanings in different disciplines. Third, appropriate tools need to be developed to deal with the different time, space and organisation level scales. These recommendations permit a more accurate picture of prospective risks.

本文介绍了2018年6月在苏格兰斯特灵举行的研讨会的结果，该研讨会旨在严格审查低剂量电离辐射对生态圈的影响。这次会议汇集了来自低剂量和高剂量放射生物学领域的人们以及从事放射生态学的人们，讨论了低剂量辐射对非人类生物群系的影响。特别是，讨论了低剂量反应关系的形状以及可以从高剂量率暴露中预测低剂量和慢性暴露影响的程度。结论是高剂量效应不能预测低剂量效应。因此，目前认为可用的工具不足以可靠地预测生态系统中低剂量暴露的风险。讲习班参加者就前进的道路提出了三项主要建议。首先，由于认为将辐射作为单一或独特的压力源是不够的，因此建议发展多学科方法来解决生态圈中多个压力源的关键问题。其次，需要一个公认的定义来处理决定低剂量暴露结果的多种因素，因为一个术语在不同学科中可能具有不同的含义。第三，需要开发适当的工具来应对不同的时间，空间和组织级别的规模。这些建议可以使您更准确地了解潜在风险。建议开发一种多学科方法，以解决有关生态圈中多种压力源的关键问题。其次，需要一个公认的定义来处理决定低剂量暴露结果的多种因素，因为一个术语在不同学科中可能具有不同的含义。第三，需要开发适当的工具来应对不同的时间，空间和组织级别的规模。这些建议可以使您更准确地了解潜在风险。建议开发一种多学科方法，以解决有关生态圈中多种压力源的关键问题。其次，需要一个公认的定义来处理决定低剂量暴露结果的多种因素，因为一个术语在不同学科中可能具有不同的含义。第三，需要开发适当的工具来应对不同的时间，空间和组织级别的规模。这些建议可以使您更准确地了解潜在风险。
