Genetic damage in mobile phone users: some preliminary findings med./bio.

Published in: Indian J Hum Genet 2005; 11 (2): 99-104

Aim of study (acc. to author)

To study DNA and chromosomal damage in the peripheral blood lymphocytes of individuals (n=24) using mobile phones, being exposed to microwave frequency ranging from 800 MHz to 2000 MHz.

Background/further details

Age- and sex-matched healthy individuals who had never used the mobile phone formed the control group.

Main outcome of study (acc. to author)

The mean comet tail length (39.75% of cells damaged) in mobile phone users was highly significant different from that in the control group. The in vivo capillary blood micronucleus test also revealed highly significant frequency of micronucleated cells.
The authors conclude, that the data highlight a correlation between mobile phone use and genetic damage.
