View Original AbstractThe study found no evidence of 1.9 GHz RF-field-induced genotoxicity in human blood cell cultures after a 24-hour exposure period.
Plain English Summary
Researchers examined the effect of 24-hour continuous-wave and pulsed-wave 1.9 GHz radiofrequency fields on primary DNA damage and micronucleus induction in human leukocyte cultures. No significant differences in primary DNA damage were observed between sham controls and any exposed cultures when assessed by the alkaline comet assay immediately after exposure. Similarly, no significant differences were found in micronucleus incidence, micronucleated binucleated cells, binucleated cell frequency, or proliferation index between sham and exposed cultures.
Why This Matters
Mean specific absorption rates ranged from 0 to 10 W/kg during the 24-hour exposure. The temperature within the cultures was maintained at 37.0 ± 1.0°C throughout the exposure period.

Where This Falls on the Concern Scale
Study Details
The current study extends our previous investigations of 2-h radiofrequency (RF)-field exposures on genotoxicity in human blood cell cultures by examining the effect of 24-h continuous-wave (CW) and pulsed-wave (PW) 1.9 GHz RF-field exposures on both primary DNA damage and micronucleus induction in human leukocyte cultures.

In conclusion, the current study found no evidence of 1.9 GHz RF-field-induced genotoxicity in human blood cell cultures after a 24-h exposure period.
