The level of technogenic non-ionizing electromagnetic radiations of various frequencies constantly grows in the biosphere. Therefore, studies of these radiations influence on biological organisms are very actual. The purpose of the work was to study the consequences of prolonged exposure to EHF radiation on the stability of the genome of anurans. Larvae of the green toad (Bufo viridis) were subjected to EMR at four different EHF frequencies (34.52, 34.67, 34.79, and 35.04 GHz with an energy flux density of 4.88, 5.33, 4.94, and 3.76 mW/cm2, respectively) for 120 hours. After irradiation the frequencies of micronuclei (MN) and nuclear anomalies (NA) in peripheral blood erythrocytes of tadpoles were studied. EHF radiation with a frequency of 34.52 GHz induced a small and statistically insignificant increase in the frequency of MN and NA. Exposure to EHF radiation at frequencies of 34.67, 34.79, and 35.04 GHz caused a statistically significant increase in the frequency of MN and NA in tadpole erythrocytes. A statistically significant increase of the frequency of MN and NA in anuran larvae erythrocytes after exposure to EHF radiation proves a certain danger of an increasing level of EMR in the biosphere, as well as the need for further studies of the effect of non-ionizing radiation on the genomes of lower vertebrates.
