The authors exposed human neuroblastoma cells to RFR at 900 MHz GSM or continuous wave (CW) for 24 hours. The SAR for CW was 2 W/kg, and for GSM was 0.25 W/kg average. During CW exposure an increase of 2°C was observed, and control cells at 39°C were also observed because of this. Apoptosis rate was assessed using 3 methods (DAPI staining; flow cytometry using double staining with TUNEL and propidium iodide; and measurement of caspase-3 activity by fluorimetry).
were no statistically significant changes in the apoptosis
rate between sham and 24-hour exposed cells, either in the
GSM-900 exposure, or in the CW.
