This study explored possible DNA damage (strand breaks) in human gliblastoma cells and mouse fibroblast cell lines exposed to microwave energy at 2450 MHz with a continuous wave signal.
It followed the publication of research findings by Drs Henry Lai and NP Singh that stated that exposure of rats at 2450 MHz at a whole-body SAR of 1.2 W/kg could induce DNA damage in brain cells. Based on analysis by alkaline comet assay (single cell electrophoresis) exposure of the cell lines in this study at SARs of 0.7 and 1.9 W/kg resulted in no detectable DNA damage.
Additional Web Notes
This is a highly controversial piece of research, one of a number done by this team for the purpose of discrediting the research of Lai and Singh. See comments on this work and on Motorola's "war gaming" of Lai-Singh.
