Published in: Electromagn Biol Med 2014; 33 (4): 296-301

Aim of study (acc. to author)

The genotoxic effects of exposure of rats to a 1800 or 2100 MHz electromagnetic field in exfoliated bladder cells should be investigated.

Background/further details

30 rats were divided into the following groups (n=6 each): 1) exposure to a 1800 MHz field for 1 month, 2) exposure to a 2100 MHz field for one month, 3) exposure to a 2100 MHz field for 2 months, 4) cage control group for 1 month, 5) cage control group for 2 months.

  • after exposure

Main outcome of study (acc. to author)

No significant differences were found in the Micronucleus formation between the exposure groups or between the individual exposure groups and their respective control groups.
The authors conclude that there is no evidence for genotoxic effects of exposure of rats to a 1800 or 2100 MHz electromagnetic in exfoliated bladder cells.
