Technology & frequency research
Find skin, eye and human sensory-threshold experiments at 26.5 and 28 GHz. These are high-intensity laboratory studies. No direct study of health outcomes in screened passengers or scanner staff was verified in the latest targeted searches.
Pain is an outcome people can recognise directly. This experiment measured when intense local millimetre-wave exposure progressed from warmth to pain, and how responses differed between participants. It provides human threshold information under a specific high-exposure protocol.
The eye is an important tissue to examine at higher frequencies. This experiment measures an injury threshold under a defined laboratory exposure.
Knowing the conditions that produce tissue injury is part of understanding an exposure. This carefully characterised experiment relates absorbed power to skin temperature and inflammation.
Knowing when someone first notices warmth helps interpret stronger exposure experiments. These measurements show that perception thresholds and their repeatability depend on the exposure level. That is useful human physiology, even though the protocol was far more intense than ordinary environmental fields.
