28 GHz: measured pain thresholds in human skin
The reported finding
Reported pain threshold temperature was 41.9°C. Women showed greater pain sensitivity than men in this sample.
Reading it carefully
Original abstract only; high-intensity thermal-sensation experiment. This does not show symptoms from everyday wireless exposure or airport screening, and demographic results need replication.
Inside the study
Technology connection
Relevant carrier-frequency research; the record distinguishes actual 5G modulation from other laboratory waveforms. High-intensity 28 GHz laboratory threshold research; not measurements of health outcomes in screened passengers or airport staff.
Publication type
Original journal research
Exposure conditions
28 GHz on the middle fingertip; incident density averaged over 1 cm² of 1.00 W/cm²; up to 10 min, stopped for pain or skin temperature above 44°C.
Design & controls
Thirty-five healthy adults; warmth, heat, tingling and pain perception during controlled local exposure.
Statistics
See the original results; effect sizes were not independently recalculated.
Related research & shared cohorts
Same Yuasa/Uehara human-sensation programme as the 2024 warmth-threshold paper; cohort independence not established. Related publication records: WEB-042.
The protection question raised
Which exposure conditions reproduce this finding, and what would establish its relevance beyond the experimental model?
Source verification
Original abstract and bibliographic identity reviewed; full methods, dosimetry and statistics not audited.
