Impact of 864 MHz or 935 MHz radiofrequency microwave radiation on the basic growth parameters of V79 cell line

View Original AbstractCell phone frequencies altered cellular growth patterns at power levels below current safety limits, with effects appearing days after exposure.
Plain English Summary
Scientists exposed lab cells to cell phone frequencies (864 MHz and 935 MHz) for up to three hours. Cell growth patterns changed significantly 72 hours after longer exposures, even though cell survival wasn't affected. This shows radiofrequency radiation can disrupt normal cellular processes days after brief exposure.
Why This Matters
This study adds to the growing body of evidence that radiofrequency radiation can affect cellular function at power levels well below current safety limits. The SAR levels used (0.08-0.12 W/kg) are actually lower than what your phone produces during a call (up to 2 W/kg), yet the researchers still observed measurable biological effects. What makes this particularly noteworthy is the delayed response - the growth changes didn't appear until 72 hours after exposure, suggesting that RF radiation may trigger cellular processes that unfold over time rather than causing immediate damage. The fact that both frequencies tested (which bracket the range used by many wireless devices) produced similar effects indicates this isn't frequency-specific but rather a general response to RF exposure. While this was a laboratory study using isolated cells, it demonstrates that biological systems can detect and respond to RF radiation at levels we encounter daily from our wireless devices.
