Study type: Medical/biological study (experimental study)

Aneuploidy studies in human cells exposed in vitro to GSM-900 MHz radiofrequency radiation using FISH med./bio.

Published in: Int J Radiat Biol 2011; 87 (4): 400-408

Aim of study (acc. to author)

To study whether radiofrequency exposure similar to that emitted by GSM mobile phones may induce aneuploidy in cultured human amniotic cells.

Main outcome of study (acc. to author)

No significant change in the rate of aneuploidy of chromosomes 11 and 17 was found following exposure to GSM-900 for 24 h at average SAR up to 4 W/kg. In conclusion, the data did not show any in vitro aneuploidogenic effect of GSM.
