Exposure to 26.5 GHz, 5G modulated and unmodulated signal, does not affect key cellular endpoints of human neuroblastoma cells
This in vitro study examined whether 26.5 GHz millimeter-wave exposure (continuous wave and 5G-modulated) affects key cellular endpoints in human neuroblastoma cells. Cells were exposed for 3 hours at SAR 1.25 W/kg using a reverberation-chamber system, with assessments including cell cycle and DNA damage. The study reports no effects from exposure alone or when combined with the oxidant menadione, while noting that additional studies across varied conditions are needed.
Key points
- The study tested 26.5 GHz millimeter-wave exposure using both continuous wave and 5G-modulated signals.
- A reverberation-chamber exposure system enabled controlled exposure and sham exposure of cell cultures.
- Exposure was 3 hours at a reported SAR of 1.25 W/kg.
- Endpoints included cell cycle-related measures and DNA damage.
- No effects were reported for either signal type at the tested exposure level.
- No cooperative effects were reported when exposure was combined with the oxidant menadione.
- The authors call for further investigations varying exposure and biological parameters to strengthen evidence.
