Effects of low level electromagnetic field exposure at 2.45 GHz on rat cornea. med./bio.

Published in: Int J Radiat Biol 2013; 89 (4): 243-249

Aim of study (acc. to author)

The effects of exposure of rats to a 2.45 GHz electromagnetic field on the cornea should be investigated.

Main outcome of study (acc. to author)

In the microscopical measurement, the anterior epithelium of the cornea of exposed animals was significantly thicker compared to the control group, whereas the cornea itself did not show significant differences in thickness. The stereological investigation did not show any significant differences.
The authors conclude that exposure of rats to a 2.45 GHz electromagnetic field could cause alterations in the cornea.
