The aim of this study was to test the hypothesis that the 930 MHz continuous
wave (CW) electromagnetic field, which is the carrier of signals emitted by
cellular phones, affects the reactive oxygen species (ROS) level in living
cells. Rat lymphocytes were used in the experiments. A portion of the
lymphocytes was treated with iron ions to induce oxidative processes.
Exposures to electromagnetic radiation (power density 5 W/m2, theoretical
calculated SAR = 1.5 W/kg) were performed within a GTEM cell. Intracellular
ROS were measured by the fluorescent probe dichlorofluorescin diacetate
(DCF-DA). The results show that acute (5 and 15 min) exposure does not affect
the number of produced ROS. If, however, FeCl2 with final concentration 10
microg/ml was added to the lymphocyte suspensions to stimulate ROS production,
after both durations of exposure, the magnitude of fluorescence (ROS level
during the experiment) was significantly greater in the exposed lymphocytes.
The character of the changes in the number of free radicals observed in our
experiments was qualitatively compatible with the theoretical prediction from
the model of electromagnetic radiation effect on radical pairs. Copyright 2004
