Ocular injury thresholds in a 76 GHz rabbit experiment
The reported finding
200 mW/cm² produced opacity, epithelial injury, miosis and inflammation; 75/100 mW/cm² produced reversible epithelial injury.
Reading it carefully
No detectable ocular changes at 10/50 mW/cm². Acute high-power hazard experiment, not automotive FMCW exposure. Conference publication type is distinct from a journal article.
Inside the study
Technology connection
Frequency-related ocular research; not an automotive FMCW radar exposure.
Publication type
Conference proceedings paper
Exposure conditions
76 GHz local eye exposure; 10, 50, 75, 100 or 200 mW/cm² for 6 min; focused lens antenna; anaesthetised, held-open rabbit eyes.
Design & controls
Conference proceedings paper; 52 pigmented rabbits across experimental procedures; slit-lamp and ocular-temperature measurements.
Statistics
See reported finding and original tables; effect sizes not independently recalculated.
The protection question raised
Which exposure conditions and biological models reproduce this response, and what would establish its relevance to health?
Source verification
Original methods/results sections reviewed; no independent raw-data or supplement audit.
Where to find the result
