View Original AbstractCell phone radiation altered essential mineral levels in rats after just one month of daily exposure at typical usage levels.
Plain English Summary
Researchers exposed rats to cell phone radiation for 20 minutes daily over a month to see if it affected essential minerals in their blood. They found that manganese and zinc levels changed significantly in exposed rats, while iron and copper remained normal. This suggests that cell phone radiation may disrupt how the body processes certain trace elements that are crucial for proper cellular function.
Why This Matters
This study adds to growing evidence that RF radiation affects biological processes beyond just heating tissue. The fact that exposure altered manganese and zinc levels is significant because these trace elements play critical roles in enzyme function, immune response, and cellular metabolism. The exposure levels used (SAR of 0.52-3.13 W/kg) are within the range of typical cell phone use, making these findings directly relevant to everyday exposure. What makes this research particularly noteworthy is that it demonstrates measurable biochemical changes from relatively short daily exposures over just one month. The selective effect on manganese and zinc, while leaving iron and copper unchanged, suggests specific biological pathways are being disrupted rather than general toxicity.
Exposure Details
- SAR
- 0.52 and 3.13 W/kg
- Exposure Duration
- 20 min per day, 7 days a week, for 1 month
Exposure Context
This study used 0.52 and 3.13 W/kg for SAR (device absorption):
- 1.3x above the Building Biology guideline of 0.4 W/kg

Where This Falls on the Concern Scale
Study Details
The objective of this study was to investigate the effects of radiofrequency radiation emitted from cellular phones on: (1) trace elements such as manganese, iron, copper, zinc, (2) T1 relaxation times in serum, and (3) rectal temperature of rats exposed to microwave radiation emitted from cellular phones.
Sixteen Spraque–Dawley rats were separated into two groups of eight, one sham-exposed (control) and ...
T1 relaxation time and the values of iron and copper in the serum of the experimental group were not...
