“…In the third exposure phase resulting from the Chernobyl accident, most strongly affected populations of species of pine trees and soil invertebrates were shown to slowly start to recover (Arkhipov et al 1994;Zelena et al 2005). Recovery from the initial negative effects was also found in birch pollen, embryonic cells of herbaceous plants like evening primrose embryonic cells (Boubriak et al 2008) and Arabidopsis thaliana (Kovalchuk et al 2004) and in exposed birds (Galvan et al 2014).…”

“…Aberrant cell frequencies were found in the root meristem of plant seedlings (Geras'kin et al 2011). Increased mutation rate (Kuchma et al 2011) and gene deregulation (Zelena et al 2005), have been seen in pine trees. Increased mitochondrial DNA haplotype and nucleotide diversity have been reported in bank voles (Matson et al 2000;Baker et al 2001), chromosomal aberrations in mice (Kubota et al 2015) and in soil invertebrates, increased DNA damage in earthworms (Fujita et al 2014).…”

“…Field and laboratory studies have indicated that acute high doses of ionising radiation between 10 and 1000 Gy can be lethal to plants, while large field studies have demonstrated that chronic radiation at 100 μGy h − 1 over multiple years is harmful to and cause persistent effects in conifers (Amiro and Sheppard, 1994;Caplin and Willey, 2018). Several studies of Scots pine and Norway spruce (Picea abies) have shown increased occurrence of abnormal morphogenesis, such as loss of apical dominance, as well as genetic and epigenetic changes as a result of releases during the ChNPP accident (Zelena et al, 2005;Geras'kin et al, 2008;Yoschenko et al, 2011;Volkova et al, 2017).…”

“…Previous work has, for instance, investigated the influence of radiation on agricultural crops (e.g., Dmitriev et al, 2011), fish (e.g., Lerebours et al, 2018) and dairy products (e.g., Labunska et al, 2018). Studies regarding the effects of radiation on forest ecosystems have to date largely focused on radiation-induced changes at the level of genes (Zelena et al, 2005), cells (Blagojevic et al, 2019) or organs (Geraskin et al, 2019). They show that conifers are more sensitive to contamination compared to broadleaved trees (e.g., Yoschenko et al, 2011Yoschenko et al, , 2017Watanabe et al, 2015), suggesting that chronic levels of radiation might have particularly severe effects in coniferous forests (Fesenko, 2019).…”

Questions Nuclear power is under increasing consideration in many countries because it is a low‐carbon strategy to satisfy growing energy demands. Yet, the long‐term environmental impacts of nuclear accidents remain unclear. Here we asked how ionizing radiation affects tree regeneration and forest development after the Chernobyl nuclear accident. We hypothesized that high levels of 137Cs contamination in the soil: (a) inhibit tree establishment; (b) accelerate structural development (i.e., facilitation of an early differentiation of tree sizes); while (c) prolonging the dominance of early‐seral deciduous communities (because of an elevated susceptibility of conifers to ionizing radiation). Location Chernobyl Exclusion Zone, Ukraine. Methods We sampled 103 plots on former agricultural lands in the Chernobyl Exclusion Zone that were abandoned after the accident in 1986. Results Contamination had no significant effect on the stem density of forests established on former agricultural lands (p = 0.769). Structural development was not accelerated by radioactive contamination (p > 0.191), but we did find weak indications that the presence of tree regeneration was reduced by high radiation levels (p = 0.054). Tree species composition did not vary significantly with contamination (p = 0.250). Individual Scots pine trees did, however, experience a considerably higher proportion of deformed stems when contamination levels were high (p = 0.009). Conclusions Our analyses confirm negative effects of radioactive contamination on the individual tree health of Scots pine, yet early stand development in the Chernobyl Exclusion Zone was largely insensitive to different levels of radiation. As wildfires threaten to remobilize and redistribute radionuclides stored in the growing forests of the Chernobyl Exclusion Zone, our findings have potential implications for human health. We conclude that forest dynamics is a key element for assessing the long‐term risk at nuclear accident sites and requires intensified research and monitoring.
