To study the effects of electromagnetic irradiation produced by 3G mobile phone on rat brain tissues in terms of magnetic resonance spectroscopy, biochemistry, and histopathological evaluations.
17 rats were divided into one exposure (n=9) and one control group (n=8).
Magnetic resonance spectroscopy allows to non-invasively examine the brain by measuring the levels of several metabolites.
Exposure | Parameters |
---|---|
Exposure 1:
1.9 Hz–2.2 GHz
Exposure duration:
every day two times 20 min (1x talking, 1x listening mode) from day 2 to day 21

Setup | rats kept in two 40 cm x 30 cm x 15 cm polypropylene cages, placed 10 m apart, with the mobile phone (either in listening or talking mode) placed in close contact to the cages' underside; after active exposure phones switched to stand-by mode and batteries charged for the rest of the day; for the control group the mobile phone was set to stand-by-mode |
No parameters are specified for this exposure.
The data did not show any difference in any of the paramters investigated between the two groups.
The authors conclude, that short-term 3G mobile phone use does not seem to have a harmful effect on rat brain tissue.
