Effects of third generation mobile phone-emitted electromagnetic radiation on oxidative stress parameters in eye tissue and blood of rats. med./bio.

Published in: Cutan Ocul Toxicol 2012; 31 (2): 89-94

Aim of study (acc. to author)

The effects of electromagnetic fields emitted by a mobile phone on oxidative stress parameters in eye tissue and blood of rats should be investigated.

Background/further details

Rats were randomly divided into a control group and an exposure group (n=9 per group).

Exposure setup
Exposure source
Setup during exposure, rats were kept in two 40 cm x 30 cm x 15 cm polypropylene cages without wood-chip bedding, placed 10 m apart; under each cage a recorder and a mobile phone was placed: for the first 20 min recorder B was turned off, recorder A was turned on and the recorded speech transmitted via phone A to phone B; during the second 20 min recorder A was turned off, recorder B was turned on and the recorded speech was transmitted via phone B to phone A; except from exposure, mobile phone was kept in standby mode for the rest of the day
Additional info batteries were charged continuously

Main outcome of study (acc. to author)

No significant differences between the control group and the exposure group were observed.
The authors conclude that electromagnetic fields emitted by a mobile phone do not induce oxidative stress in the eye tissue and blood of rats.
