Altogether 496 participants (330 female, average age: 23 years) were divided into three large groups differing in cognitive tasks subjects had to perform (see publication 14709 and publication 12885). Each subject was exposed to radio frequency electromagnetic fields emitted by mobile phone in one session and sham exposed in the other session. The sessions were about one week apart.
|Setup||The phone was attached to a cap and was positioned so that the antenna was slightly behind and above the left or right ear for half of the participants, respectively.|
|Sham exposure||A sham exposure was conducted.|
|Additional info||The approved exposure system was made for the Mobile Telecommunication and Health Research Programme in the United Kingdom [http://www.mthr.org.uk/meetings/nov_2002/summaries/human_exposure.htm].|
A statistically significant increment in dizziness was observed in only one of the three exposure groups.
No consistent evidence could be found suggesting that exposure to mobile phone radio frequency electromagnetic fields affects subjective symptoms.
