The effects of extremely low frequency electromagnetic fields exposure at 1 mT on hemogram and blood biochemistry in rats. med./bio.

Published in: Electromagn Biol Med 2021; 40 (1): 138-149

Aim of study (acc. to author)

The effects of exposure of rats to a 50 Hz magnetic field on blood parameters and morphology of liver and kidney should be investigated.

Background/further details

Rats were divided into two groups (n=30, respectively): exposure and sham exposure.

Main characteristics
Frequency 50 Hz
Type
Exposure duration 20 hours/day for 24 weeks
Exposure setup
Exposure source
Chamber plastic cages of 45 x 20 x 35 cm (L x W x H)
Setup exposure device was a rack made of plastics (1 x 2 x 2 m (L x W x H)) with five floors made of bronze wires to produce magnetic field; the top and bottom floors were made of 400 turns and the internal floors were made of 200 turns of wire; inside the device, a four-floor shelf was placed, which was also made with plastic in the center, and the height of every floor was the same as that of the device; two unrestrained rats per cage
Sham exposure A sham exposure was conducted.
