Corneal damage thresholds during high-power 28 GHz exposure

The reported finding

Acute corneal damage occurred at high incident power; the authors estimated a dose-related injury threshold.

Reading it carefully

Original abstract only. High-power animal hazard experiment, not passenger-scanner or everyday 5G exposure. A matching carrier cannot establish equivalence of dose or waveform.

Inside the study

Technology connection
Millimetre-wave laboratory biology; frequency overlap does not demonstrate effects from a deployed system.
Publication type
Original journal research
Exposure conditions
28 GHz local rabbit-eye exposure for 6 min; injury at 400 mW/cm²; estimated 50% damage threshold 359 mW/cm².
Design & controls
Rabbit ocular-response experiment; corneal epithelial injury, oedema and opacity assessed.
Statistics
See reported finding and original tables; effect sizes not independently recalculated.
Related research & shared cohorts
Related Japanese ocular programme with WEB-021, WEB-022 and WEB-017.
The protection question raised
Which exposure conditions and biological models reproduce this response, and what would establish its relevance to health?
