需要制定标准，以便能够判断与非人类生物群估计剂量率相关的风险水平。在本文中，欧洲的指导推导预测无影响的化学品浓度已适用于适当的辐射敏感性数据。一个物种敏感性分布拟合的数据，所有物种的通用预测无效应剂量率为10 μ戈伊小时（-1）。目前，数据不足以得出不同微生物组的筛选值。第二个更高的基准可以通过将结果放在没有影响到“严重”影响风险的范围内来帮助决策。这种价值观的必要性、意义和使用需要由更广泛的社区进行辩论。本文探讨了获得科学投入这一辩论的潜在方法。本文件提出的概念与人类保护框架大体一致。(C)2009爱思唯尔有限公司保留所有权利。
Criteria are needed to be able to judge the level of risk associated with dose rates estimated for non-human biota. In this paper, European guidance on the derivation of predicted no-effect chemical concentrations has been applied to appropriate radiation sensitivity data. A species sensitivity distribution fitted to the data for all species resulted in a generic predicted no-effect dose rate of 10 mu Gy h(-1). Currently, data are inadequate to derive screening values for separate organism groups. A second, higher, benchmark could aid in decision making by putting results into context on the scale of no effect to a risk of 'serious' effect. The need for, meaning and use of such a value needs to be debated by the wider community. This paper explores potential approaches of deriving scientific input to this debate. The concepts proposed in this paper are broadly consistent with the framework for human protection. (C) 2009 Elsevier Ltd. All rights reserved.
