Resolving the controversies and deciding how to interpret the results are of considerable importance. Small nuclear power reactors: Future or folly? This is not to say radiation is having no effect, just that assigning a level of effect to radiation is not possible. We consider low-dose radiation effects to be highly uncertain and influenced by other factors, such as predation or disease. Our own data gathered in Chornobyl in 2018 are still being analyzed, but preliminary findings reveal enormous individual variation and fail to show any clear statistically significant correlation between negative health effects and radiation dose. Tim Mousseau, a biologist at the University of South Carolina, has reported multiple abnormalities in a variety of species, and Rosa Goncharova, a radiation geneticist at the Institute of Genetics and Cytology, National Academy of Sciences of Belarus, has found that the descendants of animals that experienced the early high-dose radiation continue to show many chromosomal abnormalities.īut others, including Mike Wood, an environmental scientist at the University of Salford and Nick Beresford, a radioecologist at the Institute for Hydrology and Ecology at the University of Lancaster, find no evidence of such effects. The health effects of low-dose radiation in ecosystems are highly controversial. This is because of all the other stressors in the environment, including predators, parasites, disease and starvation. Yet we could not say with any certainty that the health effects we detected were due to radiation exposure. The author’s make-shift tissue culture lab in an abandoned house in the Chornobyl exclusion zone. Radiation levels in the area are variable but can lead to high doses, and some voles experienced radiation rates 40 times higher than unexposed control voles. Prior to the pandemic, we were part of a multidisciplinary team monitoring levels of radioactivity and associated health effects - anemia, cancer, cataract or immune compromise - in wild vole populations.

My own group’s work in Chornobyl seeks to understand the long-term effects of chronic exposures to low levels of radiation, as well as how these effects may be passed on from one generation to the next. The area is one of the few sites worldwide where scientists can collect field-based data on the effects of chronic exposure to radiation on wildlife. Russia suffered major contamination in areas east of the reactor, and will likely exercise extreme caution. Russian army personnel are probably passing through the area - it’s the fastest route from Belarus to Kyiv - except for a core number of troops who will likely secure the zone, much as the Ukrainian army did. By the time nature awakens, any elevated levels of radiation caused by vehicular movement will likely have settled down. Given that it’s winter, most plant and animal species are hibernating, dormant or, in the case of birds, have flown south. The risks to human and ecosystem health are difficult to estimate.

The shelter covering the remains of the damaged reactor can be seen in the background. The land and forest surrounding the Chornobyl Nuclear Power Plant remains highly contaminated.
