View Original AbstractMobile phone radiation at regulatory limits decreased liver cell survival and caused DNA damage within 4 hours of exposure.
Plain English Summary
Researchers exposed liver cancer cells to mobile phone radiation at levels typical of phone use (2 W/kg SAR) for up to 4 hours. The radiation decreased cell survival and caused DNA damage, with 1,800-MHz frequencies proving more harmful than 900-MHz. This suggests that the radiofrequency radiation from mobile phones can directly damage cells at exposure levels considered safe by current regulations.
Why This Matters
This study adds to the growing body of evidence that mobile phone radiation affects cellular health at levels well within current safety limits. The 2 W/kg SAR used here is the maximum allowed for phones in many countries, meaning millions of people regularly experience these exposure levels during typical phone use. What makes this research particularly significant is that it demonstrates both immediate cellular damage and DNA harm using multiple measurement techniques. The finding that higher frequencies cause more damage aligns with concerns about 5G networks, which operate at even higher frequencies. While this was conducted on cancer cells in laboratory conditions, it provides biological plausibility for the epidemiological studies linking mobile phone use to increased cancer risk.
Exposure Details
- SAR
- 2 W/kg
- Source/Device
- 900- and 1,800-MHz
- Exposure Duration
- 15 min on, 15 min off for 1, 2, 3, or 4 h
Exposure Context
This study used 2 W/kg for SAR (device absorption):
- 5x above the Building Biology guideline of 0.4 W/kg

Where This Falls on the Concern Scale
Study Details
This study investigated the effects of intermittent exposure (15 min on, 15 min off for 1, 2, 3, or 4 h, at a specific absorption rate of 2 W/kg) to enhanced data rates for global system for mobile communication evolution-modulated radiofrequency radiation (RFR) at 900- and 1,800-MHz frequencies on the viability of the Hepatocarcinoma cells (Hep G2).
Hep G2 cell proliferation was measured by a colorimetric assay based on the cleavage of the tetrazol...
It was observed that cell viability, correlated with the LDH and glucose levels, changed according t...
Our results indicate that the applications of 900- and 1,800-MHz (2 W/kg) RFR cause to decrease in the proliferation of the Hep G2 cells after 4 h of exposure. Further studies will be conducted on other frequency bands of RFR and longer duration of exposure.
