Aim of study (according to author)
To study the presence of a cumulative effect of brief and repeated exposures (3 X 15 min.) to a GSM mobile phone on psychomotor functions.
Background/further details:
24 subjects participated.

Endpoint

• cognitive/behavioral endpoints: psychomotor functions

Exposure
General category: mobile communication system, digital mobile phone, GSM

Field characteristics	Parameters
902.4 MHz pulsed (PW) exposure duration: intermittent, 10 min off/15 min on, for 85 min	power: 2 W peak value power: 0.25 W mean value SAR: 0.5 W/kg max value (10 g) (at the temporal lobe)

Exposed system:
human
partial body exposure: head (right ear)

Methods
Endpoint/Measurement parameters/Methodology

• cognitive/behavioral endpoints: psychomotor functions (acoustic simple reaction time task; sequential finger tapping task)

Main outcome of study (according to author)
The data showed no cumulative effects of brief and repeated electromagnetic field exposure on human psychomotor performance, although there was a non-statistical trend to shorter reaction times. In conclusion, these findings show an absence of effects with these particular exposure conditions.
