“…during foraging events or dispersal to find new territories) to encounter radionuclide contamination during their lifetimes. Current patterns of mitochondrial dynamics may also have been shaped by selection or epigenetic effects in the vole population recolonizing the contaminated CEZ area after the accident (Omar-Nazir et al 2018). Interestingly, skin fibroblasts isolated from bank voles inhabiting the contaminated area of the CEZ have greater resistance against oxidative and DNA damaging stressors and elevated basal antioxidant levels compared to cells from control voles collected from outside the CEZ (Mustonen et al 2018).…”

“…This apparent lack of adaptive evolution over a 28‐year time span is perhaps not surprising given that Microbotryum fungi have low effective population sizes (Gladieux et al., 2011) and no melanized structures. The survival rate of sporidia actually even decreased with increasing level of contamination at the site whence the strains came, which suggests that the chronic radiation exposure during their lifetime also negatively affected their resistance to further acute radiation exposure (Omar‐Nazir et al., 2018). One can indeed imagine that DNA damage accumulated in the field would render further damage more deleterious.…”

“…Mean radiation estimates from these data were then used for each location. Measurements of ambient dose are strongly positively correlated with internal dose for a wide range of organisms (Omar‐Nazir et al., 2018). For the following experiments, we used spores from 18 different strains—15 from Chernobyl, from areas with radioactive contamination varying 700‐fold, from 0.03 µSv/hr to 21.03 µSv/hr, and three control strains from uncontaminated sites but belonging to the same Central‐Eastern European genetic cluster as the Chernobyl strains (Vercken et al., 2010).…”

“…It is important to note that ARS can also evolve out of non-treatment scenarios. In the historical events that occurred in Fukushima and Chernobyl, people were exposed to radiation levels >2 Gray (Gy) (Davis 2012;Omar-Nazir et al 2018) and developed ARS (Shimura et al 2015). Reports indicated 9335 deaths linked to acute radiation exposure occurred in Chernobyl (Mousseau et al 2005;Davis 2012;Omar-Nazir et al 2018).…”

Reports indicated 9335 deaths linked to acute radiation exposure occurred in Chernobyl (Mousseau et al 2005;Davis 2012;Omar-Nazir et al 2018). Evidence has made it clear that the vascular system in the brain, mucosal cell lining of the gastrointestinal tract, and hematopoietic system of humans were most affected by high levels of radiation and so these are considered as the main organs affected during ARS.…”
