Effects of electromagnetic radiation produced by 3G mobile phones on rat brains: Magnetic resonance spectroscopy, biochemical, and histopathological evaluation med./bio.

Published in: Hum Exp Toxicol 2012; 31 (6): 557-564

Aim of study (acc. to author)

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.

Background/further details

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

Exposure 1

Main characteristics
Frequency 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
Exposure setup
Exposure source
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.

Main outcome of study (acc. to author)

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.
