Human blood cells exposed to radiofrequency fields at 800 MHz for 72 hours showed increased levels of chromosome number abnormalities, suggesting a possible athermal effect.

Plain English Summary

Summary written for general audiences

Researchers exposed human peripheral blood lymphocytes from 10 samples to radiofrequency electromagnetic fields at 800 MHz for 72 hours in a waveguide resonator at specific absorption rates of 2.9 and 4.1 W/kg. The study found increased levels of aneuploidy depending on the chromosome studied and the level of exposure, with chromosomal gains appearing to be the primary contributor. Temperature was tested over a range of 33.5–40°C for 72 hours and showed no statistically significant difference in aneuploidy levels compared to 37°C, suggesting the effect may not be due to heating.

Why This Matters

The induced aneuploidy of chromosomes 1, 10, 11 and 17 was determined by interphase FISH using semi-automated image analysis. For chromosomes 1 and 10, increased aneuploidy was observed at the higher SAR, while for chromosomes 11 and 17, increases were observed only at the lower SAR. Because the temperature control experiment showed no significant difference in aneuploidy across the tested temperature range, the researchers suggested the observed effects may not simply result from heating of the cells. The researchers noted that their results contribute to assessing potential health risks after continuous chronic exposure to RF radiation at SARs close to levels set by ICNIRP guidelines.

Quick Questions About This Study

Human peripheral blood lymphocytes from 10 samples were exposed in vitro to 800 MHz continuous-wave radiofrequency fields in a specially designed waveguide resonator.
Researchers measured aneuploidy in chromosomes 1, 10, 11 and 17, using interphase FISH with semi-automated image analysis.
The response varied: chromosomes 1 and 10 showed increased aneuploidy at the higher SAR, while chromosomes 11 and 17 showed increases only at the lower SAR.
Temperature testing over 33.5–40°C for 72 hours showed no statistically significant difference in aneuploidy, leading researchers to suggest a possible athermal effect.
The researchers stated that their results contribute to assessing potential health risks after continuous chronic exposure to RF radiation at SARs close to current ICNIRP guideline levels.
