This study tested the hypothesis that exposure to radiofrequency radiation (RFR) would affect the levels of reactive oxygen species (ROS), otherwise known as free oxygen radicals, in cells.
used rat lymphocytes in their experiment. These were exposed
to 930 MHz continuous wave radiation for either 5 minutes
or 15 minutes at a power density of 5 W/m² (theoretical
calculated SAR = 1.5 W/kg). One half of the samples were treated
with ferrous chloride (FeCl) to stimulate ROS production.
Four groups of cells were used in the experiment: group I,
not treated with FeCl and not exposed to radiofrequency radiation
There was no difference in fluorescence between the RFR-exposed and the non-exposed cells that did not have added FeCl (groups I and II). However, in groups III and IV, where the FeCl had been added, the ROS levels were higher in group IV (the RFR-exposed group. This was the case for both the 5-minute and the 15-minute exposure.
The authors stated: "At present, we cannot offer any reasonable explanation for possible mechanisms of the observed effects".
