The effect of 2.45 GHz microwave irradiation on human peripheral lymphocytes

The effect of 2.45 GHz frequency and 10 mW/cm2 power density microwave irradiation on the in vitro cultured human peripheral lymphocytes blast transformation was examined. In the number of the blast cells we did not find significant difference at cultures irradiated for 1 x 5 hours and 3 x 1 hours as compared to the controls. The number of the blast cells was found to increase when Phytohemagglutinin-stimulated lymphocyte cultures were exposed to repeated irradiation for 6 days (1 hour a day). The microwave irradiation did not influence the degree of the spontaneous blast transformation in any groups.
