1969 Soviet study showed millimeter waves weakened rat nervous systems and altered blood pressure despite surface-only absorption.
Plain English Summary
Soviet researchers exposed albino rats to millimeter wave radiation and found it weakened their nervous system function, altered blood pressure, and caused structural changes in their brains. This 1969 study was among the first to show that millimeter waves, which are absorbed primarily by surface tissues, can still affect deep internal organs. The findings suggest these frequencies may have different biological effects compared to longer wavelengths.
Why This Matters
This early Soviet research deserves attention because it demonstrated systemic health effects from millimeter wave exposure decades before 5G technology brought these same frequencies into widespread commercial use. The study's finding that millimeter waves can affect the central nervous system and cardiovascular function despite being absorbed mainly at the skin surface challenges the common assumption that surface absorption equals safety. Today's 5G networks operate in millimeter wave bands (24-100 GHz), and while power levels differ from this 1969 experiment, the biological mechanisms identified here remain relevant. The researchers' observation that millimeter waves may have distinct biological effects compared to centimeter and decimeter waves suggests we cannot simply extrapolate safety data across different frequency ranges.
Exposure Information
Specific exposure levels were not quantified in this study.
