[Radioprotective effect of low-intensity radio-frequency centimeter-band waves in lethal gamma irradiation].
Primary investigations have been carried out to determine whether low-intensity EMR of a cm range exerts the radioprotective effect. Prior to gamma-irradiation with doses LD100/30 and LD60/30 mice were exposed for 23 h to 2-8 GHz microwaves with a swing frequency of 12-14 Hz, at energy flow density of 5 +/- 1.5 mu Wt/cm2. Survival and time of death of mice were registered during a month. With absolutely lethal doses of gamma-irradiation, the application of SHF EMR delayed the time of animal death by 2.8-4.2 days and led in one of the experiments to 20% survival of mice. With doses in non-absolutely lethal range, the pretreatment of mice with EMR increased the survival by 20% in two experiments.
