Abstract

Our experiments were aimed at studying the cytogenetic effects of electromagnetic radiation of the radio frequency range (with a frequency of 925 ± 3 MHz, microwave pulse duration of 570 ± 10 μs, exposure duration of 10 minutes daily for 5 days) on irradiated animals (CBA mice) and their posterity. Using the micronuclear test (Schmid, 1975), the frequency of the occurrence of polychromatophilic (PHE) and normochromic (NHE) erythrocytes with micronuclei in the bone marrow of experimental animals was analyzed. It is established that after exposure of the erythroid germ bone marrow to electromagnetic radiation of the radio frequency range, the number of cells with micronuclei increases both in irradiated animals and their posterity, depending on the sex of irradiated animals and with a greater severity in posterity. In particular, a significant increase by 3.5–3.7 times (p ≤ 0.001) was observed in the number of PHE and NHE with micronuclei in irradiated females and a decrease by 1.7 times (p ≤ 0.001) in NHE with micronuclei in males relative to the control groups of animals. In posterity obtained from the pairing of irradiated females and males, the frequency of occurrence of PHE and NHE with micronuclei increases by 5.0–8.5 times (p ≤ 0.05), respectively, relative to the control.
