To examine the influence of high-frequency electromagnetic fields emitted by cellular phones on EEG and cognitive functions of healthy subjects.
Modulation type: pulsed
Exposure duration: 10 min
|Exposure duration||10 min|
|Distance between exposed object and exposure source||0.45 m|
|Setup||three walls and the top of the exposure shielded with absorbers|
|Sham exposure||A sham exposure was conducted.|
|electric field strength||40 V/m||-||-||-||at the head|
The evaluation of spectral power analysis revealed no effect of exposure compared to the preceding and subsequent 10 minutes without exposure as well as between exposed and non-exposed subjects. A multivariate variance analysis showed no significant statistical difference in the mean values of the different frequency bands when averaged power was calculated separately. No statistically significant differences were found in the cognitive tests between field- and sham-exposure.
