Aim of study (acc. to author)

To investigate the influence of electromagnetic fields, similar to that emitted by mobile phones, on brain activity.

Background/further details

10 women and 10 men performed a memory task with and without exposure (two weeks interval between the tests).

Endpoint

- RF field
- mobile communications
- mobile phone

Type	electromagnetic field
Exposure duration	continuous for 45 min

Exposure setup

Exposure source	dipole antenna
Distance between exposed object and exposure source	20 cm
Chamber	Faraday room
Setup	test persons were sitting in the Faraday room with the antenna fixed near their right ear

Parameters

Measurand	Value	Type	Method	Mass	Remarks
power	128 mW	mean	-	-	-

Exposed system:

human
partial body: right ear

Methods Endpoint/measurement parameters/methodology

effects on the neurological system: EEG
cognitive/behavioral endpoints: memory (auditory digit span test)

Investigated system:

investigation on living organism

Investigated organ system:

brain/CNS

Time of investigation:

during exposure

Main outcome of study (acc. to author)

Under exposure, the EEG energy of the beta waves was significanlty greater for females than for males for 11 out of 15 electrodes.
Since beta waves are associated with the shift of attention during perception, the findings suggest that the 1800 MHZ signal exerts an influence on this brain activity that might be gender-specific.
