View Original AbstractLow-level microwave radiation caused tissue damage across multiple organs in rats at exposure levels below current cell phone safety limits.
Plain English Summary
Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) for 2 hours daily over 35 days at very low power levels. The exposed rats showed significant tissue damage and oxidative stress in their brain, liver, kidney, testis, and spleen compared to unexposed control rats. This suggests that even low-level microwave radiation exposure over time may cause cellular damage throughout the body.
Why This Matters
This study adds important evidence to the growing body of research showing biological effects from microwave radiation at levels well below current safety standards. The 0.14 W/kg SAR used here is actually lower than the FCC limit of 1.6 W/kg for cell phones, yet still produced measurable oxidative damage across multiple organ systems. What makes this research particularly significant is that it examined whole-body exposure over an extended period, more closely mimicking how we're actually exposed to wireless radiation in our daily lives. The finding of oxidative stress in multiple organs suggests these effects aren't limited to one body system but represent a systemic response to microwave radiation exposure. The reality is that we're conducting a massive experiment on ourselves with wireless technology, and studies like this indicate we may be seeing the biological consequences of that experiment.
Exposure Details
- SAR
- 0.14 W/kg
- Power Density
- 0.2 µW/m²

- Exposure Duration
- 2 h a day for 35 d
Exposure Context
This study used 0.2 µW/m² for radio frequency:
- 20Mx above the Building Biology guideline of 0.1 μW/m²
- 333.3Kx 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 was to explore the effect of 2.45 GHz microwave radiation on histology and the level of lipid peroxide (LPO) in Wistar rats.
Sixty-day-old male Wistar rats with 180 ± 10 g body weight were used for this study. Animals were di...
Significantly high level of LPO was observed in the liver (p < 0.001), brain (p < 0.004) and spleen ...
we conclude that exposure to microwave radiation 2 h a day for 35 d can potentially cause histopathology and oxidative changes in Wistar rats. These results indicate possible implications of such exposure on human health.
