Main outcome of study (acc. to author)

The data showed that apoptosis could be induced in human peripheral blood mononuclear cells by exposure of 900 MHz radiofrequency electromagnetic fields (SAR 0.4 W/kg) when the exposure lasted longer than two hours. The apoptosis was induced through the mitochondrial pathway and mediated by reactive oxygen species (increase after 2-6 h exposure) and caspase-3 (increase after 4-6 h exposure), and by a decreased mitochondrial membrane potential (after 2-6 h exposure). The formation of reactive oxygen species was triggered by the conformation disturbance of lipids, protein, and DNA induced by the exposure.
