Micronucleus assay and lymphocyte mitotic activity in risk assessment of occupational exposure to microwave radiation.

This study provides direct evidence that microwave radiation can damage human DNA at occupational exposure levels. The micronucleus assay is a well-established test for detecting genetic damage, and the fact that workers showed both increased DNA damage and disrupted cell division patterns strengthens the findings. What makes this particularly relevant is that occupational microwave exposures are often much higher than what consumers experience from devices like cell phones and WiFi routers. The science demonstrates that electromagnetic radiation can indeed cause measurable genetic damage in human cells, contradicting industry claims that non-ionizing radiation is inherently safe. While this study examined workers with likely high-level exposures, it adds to the growing body of evidence showing biological effects from microwave radiation.
