Exposure, pathology and mortality data for mice, dogs and humans were examined to determine whether accurate interspecies predictions of radiation-induced mortality could be achieved. The analyses revealed that (1) days of life lost per unit dose can be estimated for a species even without information on radiation effects in that species, and (2) accurate predictions of age-specific radiation-induced mortality in beagles and the atomic bomb survivors can be obtained from a dose-response model for comparably exposed mice. These findings illustrate the value of comparative mortality analyses and the relevance of animal data to the study of human health effects.
对小鼠、狗和人类的暴露、病理学和死亡率数据进行了检查,以确定是否能够实现对辐射诱导死亡率的准确种间预测。分析表明:(1)即使没有某一物种的辐射效应信息,也可以估算出该物种每单位剂量损失的生命天数;(2)可以从暴露情况相当的小鼠的剂量反应模型中准确预测比格犬和原子弹幸存者的年龄特异性辐射诱导死亡率。这些发现说明了比较死亡率分析的价值以及动物数据对人类健康影响研究的相关性。
