Korte Nederlandstalige samenvatting:
Celculuturen van mensen en ratten werden blootgesteld aan de hoogfrequente elektromagnetische straling van mobiele telefoons. Door gebruik te maken van Neutral Comet Assay en Alkaline Comet Assay worden enkelvoudige en dubbele DNA breuken vastgesteld. Deze schade wordt niet veroorzaakt door opwarming van de cellen.

Abstract
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 (1800 MHz; SAR 1.2 or 2 W/kg; different modulations; during 4, 16 and 24h; intermittent 5 min on/10 min off or continuous wave) induced DNA single- and double-strand breaks. Effects occurred after 16 h 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.
