Univ. of Vienna: DNA breuken (niet door warmte) door GSM 1800 MHz telefoon

Dit onderzoek bevestigt de Europese Reflex studie: DNA breuken treden op door de straling van GSM telefoons. De blootstellingswaarden zijn dermate laag dat de DNA breuken niet door het opwarmingseffect veroorzaakt kunnen zijn, oftewel opnieuw een bewijs voor een niet-thermisch (nog onbekend) schadelijk mechanisme dat optreedt door hoogfrequente elektromagnetische straling.

Cultured human diploid fibroblasts and cultured rat granulosa cells were exposed to intermittent and continuous radiofrequency electromagnetic fields (RF-EMF) used in mobile phones, with different specific absorption rates (SAR) and different mobile-phone modulations. DNA strand breaks were determined by means of the alkaline and neutral comet assay. RF-EMF exposure (1800MHz; SAR 1.2 or 2W/kg; different modulations; during 4, 16 and 24h; intermittent 5min on/10min off or continuous wave) induced DNA single- and double-strand breaks. Effects occurred after 16h exposure in both cell types and after different mobile-phone modulations. The intermittent exposure showed a stronger effect in the comet assay than continuous exposure. Therefore we conclude that the induced DNA damage cannot be based on thermal effects.
