View Original AbstractMillimeter wave radiation blocked normal liver enzyme responses in rats at power levels comparable to some wireless device exposures.
Plain English Summary
Researchers exposed rats to millimeter wave radiation at 53.57 GHz for 60 days while treating them with hydrocortisone, a steroid that normally increases liver enzyme activity. The microwave radiation blocked this expected enzyme increase in a dose-dependent manner, with stronger radiation causing greater interference. This suggests that millimeter wave exposure can disrupt normal cellular processes in the liver, potentially affecting how the organ responds to hormones and medications.
Why This Matters
This study reveals how microwave radiation can interfere with fundamental cellular processes, specifically blocking the liver's normal response to hormonal signals. The frequency tested (53.57 GHz) falls within the millimeter wave spectrum increasingly used in 5G networks and emerging wireless technologies. What makes this research particularly significant is that it demonstrates biological effects at power densities as low as 1 mW/cm2, which are within ranges that people might encounter from wireless devices. The fact that radiation prevented the liver from responding normally to hydrocortisone suggests these exposures could potentially interfere with how our bodies process medications or respond to natural hormones. While this was an animal study with specific experimental conditions, it adds to the growing body of evidence that millimeter wave radiation produces measurable biological effects at cellular levels.

Exposure Context
This study used 10 , 1 µW/m² for radio frequency:
- 100Mx above the Building Biology guideline of 0.1 μW/m²
- 1.7Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
The influence of microwave irradiation on the activity of gamma-glutamyl transpeptidase (GGT) induced by hydrocortisone (HC) in the liver of rats was investigated.
Animals were subjected to microwave irradiation (frequency 53.57 GHz, power density 10 mW/cm2 and 1 ...
The results indicate that microwave radiation may block an inducible effect of HC on GGT activity in...
