Effect of short-term 900 MHz low level electromagnetic radiation exposure on blood serotonin and glutamate levels med./bio.

Published in: Bratisl Lek Listy 2015; 116 (2): 101-103

Aim of study (acc. to author)

The effects of exposure of rats to a 900 MHz electromagnetic field on the blood level of serotonin and glutamate should be investigated.

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.

Methods Endpoint/measurement parameters/methodology

Investigated system:
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.
