Plain English Summary
Researchers measured biochemical changes in saliva from 12 young men before and after using mobile phones for 15 and 30 minutes at typical exposure levels. They found that cell phone radiation significantly increased levels of superoxide dismutase (SOD), an enzyme that fights cellular damage, suggesting the body was responding to oxidative stress. This provides direct evidence that even brief phone calls can trigger measurable biological responses in human cells.
Why This Matters
This study provides compelling evidence that cell phone radiation creates oxidative stress in human cells within minutes of exposure. The researchers found measurable changes in saliva after just 15 minutes of phone use at 1.09 W/kg SAR, which is well within the legal limit of 2.0 W/kg in most countries. What makes this particularly significant is that the body's antioxidant response increased, then decreased as exposure time extended to 30 minutes, suggesting the cellular defense system may become overwhelmed with longer exposures. This research adds to the growing body of evidence showing that current safety standards, which only consider heating effects, fail to account for the biological responses occurring at much lower exposure levels during everyday phone use.
Exposure Details
- SAR
- 1.09 W/kg
- Source/Device
- 1800 MHz
- Exposure Duration
- 15 and 30 min
Exposure Context
This study used 1.09 W/kg for SAR (device absorption):
- 2.7x above the Building Biology guideline of 0.4 W/kg

Where This Falls on the Concern Scale
Study Details
The aim of this study is to Evaluate selected biochemical parameters in the saliva of young males using mobile phones

Results suggest that exposure to electromagnetic radiation may exert an oxidative stress on human cells as evidenced by the increase in the concentration of the superoxide radical anion released in the saliva of cell phone users.
