研究目的(著者による)

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

詳細情報

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

ばく露装置の詳細 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 information batteries were charged continuously
