These scientists have previously conducted experiments where human blood cells were exposed to radiofrequency radiation (RFR) for 2 hours. The blood cells showed no evidence of genotoxicity (McNamee, 2002a,b). They now report results from RFR exposure for 24 hours.

Human white blood cells were exposed to either pulsed or continuous wave 1.9 GHz RF-field for 24 hours. In different experiments, the SARs were 0, 0.10, 0.26, 0.92, 2.4, and 10 W/kg. Other cells were sham-exposed or exposed to ionizing radiation. The temperature in the cell cultures was carefully monitored and was maintained at 37°C ± 1°C throughout the 24 hours.

No significant differences were found between the RF-exposed cultures and the sham-exposed in primary DNA damage. Similarly there were no differences in the incidence of micronuclei or other measures of chromosomal damage.

The authors state that "of the four studies assessing the effect of a 24-hour RF-field exposure on genotoxicity in human blood cell cultures, only the study by Tice et al., which possessed the least efficient heat exchange properties, reported a positive effect for the induction of micronuclei".
