Abstract

The aim of this study was to evaluate and compare the influence of 864 MHz and 935 MHz radiofre- quency/microwave (RF/MW) fields on the growth, colony-forming ability, and viability of V79 cells (continuous line). Cell samples with 1×10 4 V79 cells each, were exposed to continuous wave frequen- cies of 864 MHz and 935 MHz for 1, 2 and 3 hours. Exposed samples were matched with unexposed con- trol samples. Specific absorption rate (SAR) was 0.08 W/kg for the 864 MHz or 0.12 W/kg for the 935 MHz field. Cell growth and viability were determined by counting cells every day for five days after exposure. Colony-forming ability was assessed by counting colonies seven days after exposure. The growth of the 864 MHz-irradiated cells was significant after two- and three-hour exposure 72 hours after irradiation (p < 0.05). The similar was observed 72 hours after exposure for cells exposed to 935 MHz microwaves for three hours (p < 0.05). Colony-forming ability and cell viability in V79 cells exposed to 864 MHz or 935 MHz microwaves did not significantly differ from control cells. The two applied RF/MW fields showed similar effects on the growth, colony-forming ability and viability of V79 cells. Cell growth impact was time-dependent for both fields.
