Study type: Medical/biological study (experimental study)

Cell oxidation-reduction imbalance after modulated radiofrequency radiation. med./bio.

Published in: Electromagn Biol Med 2015; 34 (4): 381-386

Aim of study (acc. to author)

The effects of exposure of hamster fibroblasts to a 1800 MHz electromagnetic field on cell viability and oxidative stress should be investigated.

Background/further details

Cells were either exposed to the electromagnetic field or not exposed (control group) for 10, 30 or 60 minutes. A positive control was conducted and all data were obtained from triplicate measurements.

Main outcome of study (acc. to author)

The amount of reactive oxygen species was significantly increased after 10 minutes of exposure compared to the control group. After 30 and 60 minutes, however, no differences were observed. All other parameters did not show any significant differences between the exposure and control group.
The authors conclude that exposure of hamster fibroblasts to a 1800 MHz electromagnetic field might influence the oxidative state in cells.
