Microwave exposure of human lymphocytes at 6.5 W/kg did not significantly increase chromosome aberrations or sister chromatid exchanges.

Plain English Summary

Summary written for general audiences

Researchers exposed human lymphocytes to 455.7 MHz microwaves from a car phone at a specific absorption rate of approximately 6.5 W/kg. No statistically significant difference was found between microwave-exposed and unexposed control samples for chromosome aberration or sister chromatid exchange frequency. When microwave exposure was followed by MMC treatment, some differences appeared between combined and MMC-only treatments, but results were inconsistent. Combined exposure with X-rays showed no indication of synergistic action between RF fields and X-rays. The authors concluded that the data do not support the hypothesis that RF fields act synergistically with chemical or physical mutagens.

Why This Matters

Temperature and humidity were kept constant during the experiments. The study aimed to analyze cytogenetic effects of microwaves emitted by a 455.7 MHz car phone.
