RESPONSES OF MAN TO HIGH INTENSITY THERMAL RADIATION
J. D. Hardy, D. Murgatroyd
Military research confirmed that high-intensity electromagnetic energy produces measurable biological effects in humans, including pain and tissue damage.
Plain English Summary
This military research examined how humans respond to high-intensity thermal radiation, measuring pain thresholds, skin temperature changes, and tissue damage in military personnel. The study investigated the biological effects of intense heat exposure on human subjects. This research provides foundational data on thermal radiation's impact on human tissue, relevant to understanding how electromagnetic energy affects the body.
Why This Matters
This military-sponsored research represents early systematic study of how intense electromagnetic energy affects human biology. While focused on thermal radiation rather than the radiofrequency fields we encounter from wireless devices, the research established crucial principles about how electromagnetic energy interacts with human tissue. The science demonstrates that electromagnetic fields can produce measurable biological effects, including pain responses and tissue changes. What this means for you is that military researchers recognized decades ago that electromagnetic energy has real biological impacts on humans. The reality is that today's wireless devices operate at much lower power levels than the thermal radiation studied here, but they share the same fundamental physics of electromagnetic energy interacting with biological tissue. This foundational research helps explain why independent scientists continue investigating EMF health effects, even when exposure levels don't cause immediate heating.

Study Details
To determine the effect of location and size of the body area exposed upon the perception of pain from high intensity thermal radiation, and to investigate whether pain thresholds change with increasing skin area irradiated.
A large area source (0.6 m x 1.8 m) was designed and constructed which could irradiate uniformly (+ ...
a. The report of pain is not related uniquely to the irradiance or the exposure time; b. The pain wa...
1. In contrast to other skin sensations, pain does not summate appreciably as area of stimulation is increased. 2. Pain is predictably related to skin temperature level and is evoked by thermal radiation at skin temperatures di - 47° depending on location and size of exposed skin area. 3. Intense heat sensation, vasomotor and other reactions may be important as well as pain in limiting a man's response to high intensity thermal radiation pulses.
