No genes showed consistent expression changes in white blood cells after repeated 50 Hz EMF exposures.

Plain English Summary

Summary written for general audiences

Seventeen pairs of male volunteers aged 20-30 were exposed to a 50 Hz electromagnetic field at 62.0 ± 7.1 μT for two hours or to a sham exposure at 0.21 ± 0.05 μT. The exposure sequence was repeated the next day and again six days later with a null exposure of 0.085 ± 0.01 μT replacing the sham. Researchers examined 16 genes previously reported to respond to ELF-EMF exposure using Illumina microarrays on pooled RNA samples. No genes or gene sets showed consistent response profiles to the repeated ELF-EMF exposures. A transient cortisol increase occurred at the onset of both exposure and sham on the first day, diminishing over subsequent sessions and attributed to protocol-related stress.
