To examine potential behavioral changes in rats exposed to a 50 Hz-magnetic field (10 mT, sinusoidal).
A control group and an exposure group were examined. (n=38 per group)
ばく露時間: continuous for 21 days
|ばく露時間||continuous for 21 days|
|Distance between exposed object and exposure source||1.2 cm|
|ばく露装置の詳細||eight serially connected copper solenoids with 560 turns each and a soft iron core; coils positioned vertically; plastic cages placed 1.2 cm above the coils on a 1 cm thick wooden plate|
|Sham exposure||A sham exposure was conducted.|
No differences between the exposed group and the control group were observed regarding locomotor activity and exploration behavior. However, in the exposed group, rats showed significantly more anxiety in the elevated plus maze when compared to the control group.
The authors conclude that exposure to 50 Hz-magnetic field (10 mT, sinusoidal) could promote anxiety-related behavior in rats.
