Bats are a protected species and as such may be an object of protection in radiological assessments of the environment. However, there have previously been only few radioecological studies of species of bats. In this paper, results for >140 measurements of (90)Sr and (137)Cs in 10 species of bats collected within the Chernobyl zone are presented. There was some indication of a decreasing transfer of (90)Sr with increasing deposition, although this was inconsistent across species and explained little of the observed variability. There was no difference between male and female bats in the transfer (expressed as the ratio of whole-body activity concentrations to those in soil) of either radionuclide. There was considerable variability in transfer across all species groups. At two sites where there were sufficient data, Eptesicus serotinus was found to have higher transfer than other species.
蝙蝠是受保护物种，因此在环境放射性评估中可能是保护对象。然而，此前关于蝙蝠物种的放射生态学研究很少。本文展示了在切尔诺贝利地区收集的10种蝙蝠中超过140次对锶-90和铯-137的测量结果。有迹象表明，随着沉降量增加，锶-90的转移量有所下降，尽管这在不同物种间并不一致，且只能解释所观察到的变异性中的一小部分。两种放射性核素在雄性和雌性蝙蝠体内的转移情况（以全身活度浓度与土壤中活度浓度的比值表示）没有差异。所有物种组之间的转移情况存在很大变异性。在有足够数据的两个地点，发现棕蝠的转移量高于其他物种。
