View Original AbstractMicrowave radiation at cell phone levels reduced immune cell production in rats after just 15 days of exposure.
Plain English Summary
Croatian researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 2 hours daily over periods up to 30 days. They found that longer exposures significantly reduced lymphoblasts, which are immature immune cells that develop into infection-fighting lymphocytes. The researchers interpreted this as a stress response in the blood-forming system, suggesting the body was adapting to the microwave exposure.
Why This Matters
This study adds to growing evidence that microwave radiation affects immune system function, even at relatively low exposure levels. The SAR levels used (1-2 W/kg) are comparable to what you experience when holding a cell phone to your head during a call. What makes this research particularly significant is that it demonstrates measurable immune system changes with chronic, low-level exposure - the kind we increasingly face in our WiFi-saturated environment. The researchers' characterization of these changes as 'adaptation' rather than harm doesn't diminish the concern. The reality is that forcing your immune system to constantly adapt to artificial radiation represents an unnecessary biological burden that could compromise your body's ability to fight infections and other health challenges.
Exposure Details
- SAR
- 1 to 2 W/kg
- Power Density
- 5 to 10 µW/m²
- Source/Device
- 2.45 GHz
- Exposure Duration
- 2, 8, 15 or 30 days, for 2 h a day, 7 days a week.
Exposure Context
This study used 5 to 10 µW/m² for radio frequency:
- 500Mx above the Building Biology guideline of 0.1 μW/m²
- 8.3Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
This study used 1 to 2 W/kg for SAR (device absorption):
- 2.5x above the Building Biology guideline of 0.4 W/kg
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 2.45 GHz microwave (RF/MW) irradiation on blood-forming cells after whole-body irradiation of rats was investigated.
The exposures were conducted with a field power density of 5-10 mW/cm2, and whole-body average speci...
Significant decrease in lymphoblast count was obtained at 15 and 30th experimental day (P < 0.05), w...
The findings point out at stress response in blood-forming system in rats after selected microwave exposure, which could be considered rather as sign of adaptation than malfunction.
