Abstract

It was shown for the first time that the exposure of mouse blood leukocytes to low-intensity modulated extremely high-frequency electromagnetic radiation (EHF EMR) with effective parameters (carrier frequency of 42.2 GHz, intensity of 0.1 mW/cm², exposure duration for 20 min, modulation frequency of 1 Hz) before and after the treatment with X-rays in a dose of 5 Gy caused pronounced radiation protective effect which is manifested as a decrease in DNA damage. It is supposed that the mechanisms of the radiation protective effect are connected with an induction of adaptive response by reactive oxygen species.
