42.2 GHz millimeter waves showed no genetic damage in mice blood cells after three days of exposure.
Plain English Summary
Summary written for general audiences
Researchers exposed mice to 42.2 GHz millimeter wave radiation for 30 minutes daily over three days and found no genetic damage in blood or bone marrow cells. The study also tested whether this radiation would worsen damage from a cancer drug, but found no interaction. This suggests 42 GHz waves at these power levels don't cause detectable DNA damage in mice.

}Quick Questions About This Study
No, mice exposed to 42.2 GHz millimeter waves for 30 minutes daily over three days showed no increase in micronuclei, which are markers of genetic damage in blood and bone marrow cells.
The study used 31.5 mW/cm² power density with a peak absorption rate of 622 W/kg, which is higher than typical consumer exposures but relevant for occupational or near-antenna scenarios.
The study found no interaction between 42.2 GHz radiation and cyclophosphamide, a cancer drug. Mice exposed to both showed the same level of genetic damage as those receiving only the drug.
Mice received 30-minute daily exposures to their nasal region for three consecutive days, then researchers analyzed their blood and bone marrow cells 24 hours after the final exposure.
42.2 GHz falls within millimeter wave bands used by some 5G networks, military radar systems, and industrial applications, though consumer device exposures are typically much lower than tested levels.
