Study type: Medical/biological study (experimental study)

Effects of 100 µT extremely low frequency electromagnetic fields exposure on hematograms and blood chemistry in rats. med./bio.

Published in: J Radiat Res 2016; 57 (1): 16-24

Aim of study (acc. to author)

The effect of exposure of rats to a 50 Hz magnetic field on hematologic parameters and the function of liver and kidneys should be investigated.

Background/further details

Rats were divided into two groups (n=64 each): 1) exposure and 2) sham exposure.

Frequency 50 Hz
Type
Exposure duration continuous for 20 h/day for 3 months
Exposure setup
Exposure source
Chamber plastic cages of 45 Π20 Π35 cm (L ΠWΠH)
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 un-restrained rats per cage
Sham exposure A sham exposure was conducted.

Main outcome of study (acc. to author)

No significant differences were found between the exposure group (group 1) and the sham exposure group (group 2).
The authors conclude that exposure of rats to a 50 Hz magnetic field has no effect on the investigated hematologic parameters or the function of liver and kidneys.
