Abstract

Irradiation of cancer cells by non-ionizing millimeter waves (MMW) causes increased cell mortality. We examined if MMW have toxic effects on healthy mice. To that end, the skin of healthy C57BL/6 mice was irradiated locally at the right flank with 101 GHz MMW in a pulsed (5–10 µs) regime using a free electron laser. Irradiation was performed in a dose-dependent manner, with 20–50 pulses and a power range of 0.5–1.5 kW. Physical, physiological, and pathological parameters as well as behavior were examined before and after irradiation. Our results showed that all parameters were within normal range for all experimental mice groups and for the control group. No significant changes were noted in the physical, physiological, or behavioral status of the mice following irradiation as compared with the control group. In addition, no significant changes were found in locomotor, exploratory behavior, or anxiety of the irradiated mice and no pathological changes were noted following the hematological and biochemical blood analysis. Our results indicate that irradiation of healthy mice with MMW does not cause any general toxic effects. Bioelectromagnetics.
