Exposure of Human Mononuclear Leukocytes to Microwave Energy Pulse-Modulated at 16 or 60 Hz

Human mononuclear leukocytes were exposed to 2450-MHz microwaves pulse mondulated at 16 or 60 Hz, at specific absorption rates up to 4 mW/ml. Such exposures produced no detectable effects on leukocyte viability, or on unstimulated or mitogen-stimulated DNA synthesis or total protein synthesis. The data provided no evidence that exposure to pulse-modulated microwaves is more Iikely to alter human leukocyte function than is exposure to continuous waves at equivalent energy levels.
