Aim of study (acc. to author)

Background/further details

Serotonin and glutamate were investigated as crucial factors for the function of the brain.
9 anesthetized rats were exposed to the electromagnetic field. Shortly before (control values) and after the exposure, a blood sample was taken from each rat.

Endpoint

Exposure

Exposure	Parameters
Exposure 1: 900 MHz Modulation type: FM Exposure duration: continuous for 45 minutes	electric field strength: 15.14 V/m (in the head region) power density: 608 mW/m² (in the head region)

Exposure 1

Main characteristics

Frequency	900 MHz
Type	electromagnetic field
Exposure duration	continuous for 45 minutes

Modulation

Modulation type	FM
Modulation frequency	100 kHz

Exposure setup

Exposure source	fixed equivalent frequency emitter device
Setup	rats were grouped by three and placed on a plexiglass plate with the antenna placed at a distance of 0.5 - 1 cm from their head

Parameters

Measurand	Value	Type	Method	Mass	Remarks
electric field strength	15.14 V/m	-	measured	-	in the head region
power density	608 mW/m²	-	measured	-	in the head region

Additional parameter details

energy transmitted was equal to energy transmitted by a mobile phone

Exposed system:

animal
rat/Wistar albino
partial body: head

Methods Endpoint/measurement parameters/methodology

Investigated system:

blood samples

Time of investigation:

before exposure
after exposure

Main outcome of study (acc. to author)

The serotonin level was significantly increased after exposure compared to the measurement before, whereas the glutamate level was not changed significantly.
The authors conclude that exposure of rats to a 900 MHz electromagnetic field could have an effect on the serotonin blood level.
