View Original AbstractMicrowave radiation at WiFi frequencies caused 56% more cellular damage in rats, but antioxidants provided significant protection.
Plain English Summary
Researchers exposed rats to WiFi-frequency radiation for 8 weeks and found it caused 56% more cellular damage from oxidation within 24 hours. However, giving rats antioxidants like vitamin C beforehand protected against this damage, suggesting potential protective strategies.
Why This Matters
This study provides clear evidence that microwave radiation at 2.45 GHz creates oxidative stress in living tissue, demonstrating a fundamental biological response to EMF exposure. The power density used (6 mW/cm²) is within range of what you might encounter from some wireless devices in close proximity, making these findings relevant to everyday exposures. What's particularly significant is that the researchers demonstrated both the problem and a potential solution - showing that antioxidants can provide measurable protection against EMF-induced cellular damage. This supports the growing body of research indicating that EMF exposure triggers oxidative stress, one of the key mechanisms by which electromagnetic fields may affect human health.
Exposure Details
- Power Density
- 6 µW/m²
- Source/Device
- 2.45 GHz
- Exposure Duration
- 8 weeks
Exposure Context
This study used 6 µW/m² for radio frequency:
- 600Mx above the Building Biology guideline of 0.1 μW/m²
- 10Mx 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 aim of this study is to observe the Effects of 2.45 GHz microwave exposures on the peroxidation status in Wistar rats.
The effects on the lipid peroxidation status (LPS) of whole body irradiation of 120 Wistar rats with...
The MW exposures caused an increase in the LPS from the mean control value of 4.18 x 10(-6)g 1(-1)to...
The results obtained from this study demonstrate that MW exposures cause significant increase in the LPS and there are protective effects of the anti-oxidants ascorbic acid and alpha-tocopherol.
