This study is identical to that of McNamee et al (2002 a) except that a pulse-modulated field was used rather than a continuous-wave field.

Human blood cultures from five volunteers were exposed to a 1.9 GHz pulse-modulated 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.
