Low dose radiation effects have been investigated in Chernobyl for many years but there is uncertainty about initial doses received by many animal species. However, the Fukushima Dai-ichi Nuclear Power Plant accident opens an opportunity to study the effects of the initial low historic dose on directly exposed species and their progeny during a time where the contaminating radionuclides are decaying. In this paper, it is proposed that historic acute exposure and its resulting non-targeted effects (NTEs) may be partially involved in the high mortality/abnormality rates seen across generations of pale grass blue butterflies (Zizeeria maha) around Fukushima. Data from Hiyama et al. (2012) on the morphological abnormality frequencies in Z. maha collected around Fukushima and their progeny were used in this paper. Two dose reconstruction methods based on the Gaussian plume model were used to determine the external absorbed dose to the first exposed generation from both ground shine and plume shine. One method involved the use of the dose rate recorded at the time of collection and only took Cs-137 into account. The other involved using release rates and atmospheric conditions to determine the doses and considered Cs-137 and Cs-134. The reconstructed doses were plotted against the mortality rates and abnormality frequencies across generations. The mortality rates of the progeny from irradiated progenitors increased linearly with the increasing historic radiation doses reconstructed using both Cs-137 and Cs-134 sources. Additionally, a higher level of morphological abnormalities was observed in progeny than in the progenitors. The mean abnormality frequencies also increased throughout generations. As these results are a sign of NTEs being involved, it can be suggested that increasing mutation levels across generations may result, in part, from NTEs induced by the initial low dose received by the first exposed generation. However, continual accumulation of mutations over generations in their natural contaminated habitats remains a likely contributor into the observed outcome.

切尔诺贝利已经研究了低剂量辐射效应，但许多动物物种所接受的初始剂量尚不确定。但是，福岛第一核电站事故在污染性放射性核素正在腐烂的时期为研究直接历史低剂量对直接暴露的物种及其后代的影响提​​供了机会。本文提出，历史性急性暴露及其导致的非目标效应（NTE）可能部分与福岛周围几代浅蓝色蝴蝶（Zizeeria maha）所见的高死亡率/异常率有关。来自Hiyama等人的数据。（2012）关于Z. maha的形态异常频率本文使用了在福岛附近收集的果蝇及其后代。使用两种基于高斯羽状流模型的剂量重建方法来确定地面光泽和羽状光泽对第一暴露代的外部吸收剂量。一种方法涉及使用收集时记录的剂量率，并且仅考虑Cs-137。另一个涉及使用释放速率和大气条件来确定剂量，并考虑了Cs-137和Cs-134。针对几代人的死亡率和异常频率绘制了重建剂量。随着使用Cs-137和Cs-134光源重建的历史辐射剂量的增加，受辐射祖细胞的子代死亡率线性增加。此外，在后代中观察到的形态异常水平高于祖先。平均异常频率在整个世代中都增加了。由于这些结果是涉及NTE的迹象，因此可以暗示，各代之间突变水平的提高可能部分是由第一代暴露的最初接受的低剂量诱导的NTE引起的。但是，突变在其自然污染的生境中历代不断积累，仍然可能是所观察到的结果的原因。由暴露的第一代人接受的初始低剂量诱导的NTE引起。但是，突变在其自然污染的生境中历代不断积累，仍然可能是所观察到的结果的原因。由暴露的第一代人接受的初始低剂量诱导的NTE引起。但是，突变在其自然污染的生境中历代不断积累，仍然可能是所观察到的结果的原因。
