A research consortium led by the University of Applied Sciences Darmstadt and Incos Boté GmbH (Alzey, Germany) conducted a comprehensive study about potential genotoxicity induced by GSM-modulated electromagnetic signals at 1800 MHz in human peripheral lymphocytes. Four genotoxicity tests with different end points were conducted: (1) chromosome aberration test (five types of structural aberrations), (2) micronucleus test, (3) sister chromatid exchange test, and (4) the alkaline comet assay (Olive tail moment and % DNA). The IT'IS Foundation provided a novel and enlarged 8-wave-guide system with 4 different simultaneous exposure levels, and the appropriate electrothermal dosimetry. The study reports no significant and reproducible exposure effect on any end point tested. The human lymphocytes (yielded from peripheral blood samples) were sham-exposed and intermittently exposed (5' on / 10' off) for 28 h at SAR levels of 0.2 W/kg, 2 W/kg, and 10 W/kg.
In conclusion, the results show no evidence of a genotoxic effect induced by GSM exposure at 1800 MHz. This is consistent with previous results showing no response in human peripheral lymphocytes.
