To investigate the acute and chronic effects of electromagnetic fields emitted by mobile phones on reaction time in male and female students (n=160).
Each experiment (either real or sham exposed) was repeated five times. The test persons were not aware of the order of real/sham exposure.
For chronic effects, the test persons were divided into three groups according to the duration of their mobile phone usage: low level (total exposure <200 h, n=35), moderate (201-600 h, n=98) and frequent (>600 h, n=27) users of mobile phones.
ばく露時間: 5 x 10 min. (in random order with sham exposure and 30 min. rest in between)

It was shown that the visual reaction time was significantly decreased after exposure to electromagnetic fields emitted by a mobile phone.
No chronic effects were observed. There was no significant difference between low level, moderate and frequent users of mobile phones.
