NON-IONIZING ELECTROMAGNETIC RADIATION AND POLLUTION OF THE ATMOSPHERE
J.A. Tanner, C. Romero-Sierra · 1971
Research on electromagnetic radiation from laptop computers, combining RF emissions (WiFi, Bluetooth) and ELF magnetic fields from electronics.
Your laptop sits inches from your body for hours each day, emitting radiofrequency radiation from its WiFi antenna and extremely low frequency magnetic fields from its internal components. These emissions span a remarkably wide range, from 50 Hz power frequencies up to 5.8 GHz wireless signals, creating what researchers call a "mixed exposure environment" right on your lap or desk. What makes laptops particularly concerning from an EMF perspective is their proximity to your body combined with duration of use.

This 1971 French study investigated whether pulsed and modulated UHF electromagnetic radiation could influence the development of Trypanosoma equiperdum infections in laboratory animals. The research examined the relationship between EMF exposure and parasitemia (parasite levels in blood), representing early work connecting electromagnetic fields to biological infection processes.

This 1971 government study measured radiofrequency and microwave radiation levels from man-made sources throughout the Washington DC area. The research documented the electromagnetic environment in the nation's capital, providing baseline measurements of RF and microwave exposure from various transmission sources. This early work helped establish understanding of urban electromagnetic pollution levels during the dawn of the wireless age.

This 1970 technical report examined RF energy exposure levels from portable radio operators using 30 MHz frequencies. Researchers used phantom models and tissue simulation techniques to measure how much radiofrequency energy was deposited in human tissue during radio operation. The study represents early efforts to quantify occupational RF exposure from handheld communication devices.

Researchers identified three populations treated with microwave diathermy at 2450 MHz for study. A second group comprises older patients with fair to poor health receiving weekly treatments for up to two years for temporomandibular joint conditions.

Chamber length is determined by the antenna size and the highest test frequency. Chamber width must keep the angle of incidence at or below 60 degrees to maintain absorber performance. Tapered chambers can achieve better performance at lower frequencies and lower cost than rectangular chambers.

This 1970 technical report examined how the averaging time settings on microwave measurement instruments affect the accuracy of power density readings. The research focused on understanding measurement variability when assessing microwave radiation levels. This work was foundational for establishing proper protocols for measuring microwave exposures.
