Several United Nations organizations sought to dispel the uncertainties and controversy that still exist concerning the effects of the Chernobyl accident. A Chernobyl Forum of international expertise was established to reach consensus on the environmental consequences and health effects attributable to radiation exposure arising from the accident. This review is a synopsis of the subgroup that examined the radiological effects to nonhuman biota within the 30-km Exclusion Zone. The response of biota to Chernobyl irradiation was a complex interaction among radiation dose, dose rate, temporal and spatial variation, varying radiation sensitivities of the different taxons, and indirect effects from other events. The radiation-induced effects to plants and animals within the 30-km Exclusion Zone around Chernobyl can be framed in three broad time periods relative to the accident: an intense exposure period during the first 30 d following the accident of 26 April 1986; a second phase that extended through the first year of exposure during which time the short-lived radionuclides decayed and longer-lived radionuclides were transported to different components of the environment by physical, chemical and biological processes; and the third and continuing long-term phase of chronic exposure with dose rates<1% of the initial values. The doses accumulated, and the observed effects on plants, soil invertebrates, terrestrial vertebrates and fish are summarized for each time period. Physiological and genetic effects on biota, as well as the indirect effects on wildlife of removing humans from the Chernobyl area, are placed in context of what was known about radioecological effects prior to the accident.

Recommendations for decontamination of the urban environment in case of large-scale radioactive contamination should be distributed to management of nuclear facilities having the potential of substantial accidental radioactive release (NPPs and reprocessing plants) and to authorities of adjacent regions. Research Generally, physical and chemical processes involved in environmental countermeasures and remediation technologies, both of mechanical nature (radionuclide removal, mixing with soil, etc.), chemical nature (soil liming, fertilisation, etc.) or their combinations, are understood well enough in order to be modeled and applied in similar circumstances worldwide. Much less understood are the biological processes that could be used in environmental remediation, e.g., re-profiling of agricultural production, bioremediation, etc. These processes require more research. An important issue that requires more sociological research is perception by the public of the introduction, performance and withdrawal of countermeasures in case of emergency, as well as development of social measures aiming at involvement of the public in these processes at all stages beginning with the decision making.

“…Zainullin and the colleagues examined D . melanogaster populations near the Chernobyl nucleic power plant from 1986 to 1989 [ 17 ]. They reported that lethal X chromosome were found at prominently higher frequencies, 0.0104 in Red Forest (2 km away from the power plant, >2400 μSv/h of the ambient radiation level) in 1987 and 0.0036–0.0053 in a collection point named Chernobyl (14 km apart, 60 μSv/h) in 1986, implying a strong genetic impact of environmental irradiation on the Drosophila populations.…”

Frequencies of chromosomal inversions in Drosophila melanogaster in Fukushima after the nuclear power plant accident

et al. 2018

In order to investigate genetic impact of a large amount of radionuclides released by the Fukushima Dai-ichi Nuclear Power Plant accident in 2011, we surveyed 2,304 haploid genomes of Drosophila melanogaster collected in three localities in Fukushima in 2012 and 2013 for chromosomal inversions. No unique inversion was found in 298 genomes in 2012 and only two in 2,006 genomes in 2013. The observed frequencies were even lower than the long-term average frequency of unique inversions in Japan. The common cosmopolitan inversions were also examined in Fukushima, Kyoto, and Iriomote (Okinawa) in 2012. Among three samples in Fukushima, the flies in Iizaka, where environmental radiation level was the highest, showed the lowest frequency of In(2L)t, but the highest frequency of In(3R)P, contrary to the expectation of decreasing of their frequencies in higher polluted areas. These results suggest that, at this level of genetic analysis, Fukushima populations of D. melanogaster would not have been negatively impacted following the release of radionuclides. Transposable P-element mobility was not likely to induce DNA damage solely or synergistically with radioactivity, because their transposition activity was totally repressed in the Fukushima strains. However, it should be noted that, because of limitations in access to the exclusion zone, we could only sample the populations in areas of relatively low radioactive contamination (0.39–0.63 μSv/h). Therefore, the present study is likely to be underpowered to detect any effects that might be expected in heavily contaminated areas.
