# WEB-043 — 75–105 GHz: persistent shape changes in lung-cancer cells

Why this matters
A short exposure was followed by observations over two weeks, rather than a single immediate measurement. The researchers reported lasting changes in cancer-cell shape and growth. This is biological research within a radar-related frequency range, although it used a broad sweep rather than a car radar signal.

Doi: 10.3390/app10093187

Topic: W-band cellular responses; Automotive-radar frequency research; Cell morphology and senescence

Verification Group: Original text reviewed

Record Role: Original text reviewed

Featured: False

Exposure: 75–105 GHz sweep; reported incident density 0.2 mW/cm²; 2 or 4 min exposure, followed for 14 days.

Design: H1299 lung-cancer cells; irradiated, handled-unirradiated and incubator controls; microscopy.

Finding: Cell/nuclear morphology changed over subsequent days in patterns the authors associated with apoptosis and accelerated senescence.

Statistics: See the original results; effect sizes were not independently recalculated.

Boundary: Cancer-cell experiment; morphology alone is not a complete mechanistic diagnosis. Medium strongly attenuated power reaching cells. No automotive FMCW signal or normal-tissue hazard was established.

Related: Companion Komoshvili 2020 mortality paper; shared group/cell system, not two independent replications. Related publication records: WEB-044.

Protection Question: Which exposure conditions reproduce this finding, and what would establish its relevance beyond the experimental model?

Access: Original methods/results and interpretation reviewed; raw data and supplements were not independently audited.
