Behavioral in-effectiveness of high frequency electromagnetic field in mice. med./bio.

Published in: Physiol Behav 2015; 140: 32-37

Aim of study (acc. to author)

The effects of an whole body exposure of mice to a 2.45 GHz electromagnetic field on anxiety, obsessive and depression behaviors should be investigated.

Background/further details

Mice were assigned to one the following groups (n=8 each): 1) exposure and 2) sham exposure for anxiety behavior tests, 3) exposure and 4) sham exposure for obsessive compulsive disorders tests, 5) exposure and 6) sham exposure for depression-like behavior tests. All tests were conducted after 7, 30, 60, 90 and 120 days of exposure.

Main characteristics
Frequency 2.45 GHz
Type
Exposure duration repeated daily exposure for 1 h for 120 days
Exposure setup
Exposure source
Chamber made of non-magnetic materials like stainless steel framework, aluminium sheets and/or foils and opaque polypropylene cages; ventilation was provided over a aluminium sieve window, which was impermeable for areal electromagnetic fields; a small air circulation fan shielded by aluminium filter layers and shielded LED lights were installed
Setup a pair of commercially available mobile phones without SIM cards, having inbuilt class-I Bluetooth devices operating only in file transfer mode was fixed inside exposure chamber; temperature was 25 ± 1°C during exposure
Sham exposure A sham exposure was conducted.

  • after exposure

Main outcome of study (acc. to author)

No significant differences were found between the exposure groups (1, 3, 5) and their corresponding sham exposure groups (2, 4, 6).
The authors conclude that the present study gives no indications of an effect of an exposure of mice to a 2.45 GHz electromagnetic field on anxiety, obsessive compulsive disorders and depression-like behavior.
