In this study human blood cultures from five volunteers were exposed to a 1.9 GHz continuous-wave radiofrequency field (RF) for 2 hours. In different experiments mean SARs were 0.0, 0.1, 0.26, 0.92, 2.4, and 10 W/kg respectively. Temperature was maintained at 37.0 ± 0.5 °C.

There was no evidence of DNA damage from the alkaline comet assay that is used in many of the other papers that examine this issue. Similarly, there was no evidence of any increase in micronuclei formation compared with controls.

The authors compare their results with those obtained by other authors. They postulate that the increase in micronuclei formation observed by Zotti-Martelli et al. (2000) may have been due to sample heating, and that the results of Tice et al. (2002), obtained after 24 hours incubation, could have resulted from changes in the pH of the samples. They are not able to explain the different results reported by d'Ambrosio et al. (2002).
