Researchers exposed human blood cells to cell phone radiation at 847.74 MHz for 24 hours to see if it would damage DNA or cause chromosome breaks. They found no significant genetic damage compared to unexposed cells, even at high exposure levels (4.9-5.5 W/kg SAR). This suggests that this particular frequency and exposure duration may not directly harm cellular DNA.

Researchers exposed mouse cells to 2.45 GHz microwave radiation (the same frequency used in microwave ovens) at levels 20 times higher than safety limits for 4 hours. The radiation significantly increased the activity of RNase L, an enzyme involved in the body's antiviral defense system. This suggests that microwave radiation can trigger cellular stress responses even when cells appear healthy and continue growing normally.
