At 30 mW/cm2 and exposures of 30 and 60 minutes, both tested frequencies induced micronuclei in human lymphocytes in vitro.

Plain English Summary

Summary written for general audiences

Researchers exposed human peripheral blood lymphocytes in vitro to electromagnetic fields at two frequencies, 2.45 and 7.7 GHz, at power densities of 10, 20, and 30 mW/cm2 for 15, 30, and 60 minutes. At a power density of 30 mW/cm2 and after exposures of 30 and 60 minutes, both frequencies led to an induction of micronuclei compared to control cultures. The researchers concluded that microwaves are able to cause cytogenetic damage in human lymphocytes mainly for both high power density and long exposure time.

Why This Matters

The micronucleus assay was used as the measure of cytogenetic damage, described as a useful tool for detecting radiation exposure-induced cytogenetic damage. The lymphocytes were exposed in G0 across a range of conditions varying frequency, power density, and duration. The increased micronuclei were observed at 30 mW/cm2, and the study indicates that high power density and long exposure time were the key factors.
