IMMUNOLOGICAL REACTIVITY OF ANIMALS IN PROLONGED IRRADIATION BY ULTRA HIGH FREQUENCY RADIOWAVES

I. S. Dronov, A. D. Kiritseva · 1972

This 1972 Soviet research examined how prolonged ultra high frequency (UHF) radio wave exposure affected the immune system function of laboratory rabbits. The study specifically measured changes in phagocytic activity (the ability of immune cells to engulf harmful particles) and complement levels (proteins that help fight infections). This represents early scientific investigation into whether radiofrequency radiation could weaken immune defenses.

FIELD TESTING OF MICROWAVE OVENS

Office of Training, Division of Electronic Products · 1972

Interlock testing requires at least two operable safety interlocks and the oven should turn off before leakage exceeds 5 mW/cm² during slow door opening. Closed-door leakage measurements use a standard water load of 275 ml in a 600 ml beaker and the probe is moved along the door crack at no faster than one inch per second. Ovens manufactured after October 6, 1971 must bear a DHEW certification label showing compliance with 42 CFR Part 78.

ACCELERATED DRYING OF PLASTER CAST WITH A MICROWAVE OVEN

Charles Asbelle, Gerald Porter · 1972

This 1972 technical report examined using microwave ovens to accelerate the drying process of plaster casts, developing prototype equipment for this application. The research focused on the engineering aspects of applying microwave energy to medical materials rather than health effects. This represents early exploration of microwave technology in healthcare settings before widespread understanding of EMF exposure risks.

Radio Frequency and Microwave Radiation

Unknown authors · 1972

The guide defines radio frequency and microwave bands from 10 MHz to 300 GHz and describes common sources such as radar, communication systems, medical diathermy, and microwave ovens. It explains that microwaves interact with tissue mainly by converting electromagnetic energy to heat, with penetration depth depending on wavelength. ANSI recommends a maximum power density of 10 mW/cm² for exposures of 0.1 hour or more. ACGIH sets a threshold limit value of 10 mW/cm² for continuous exposure and 25 mW/cm² for intermittent exposure.

Comments on Human Exposure to Nonionizing Radiant Energy – Potential Hazards and Safety Standards

L. Birenbaum · 1972

This 1972 research by Birenbaum examined human exposure to microwave radiation and its potential health hazards, with particular focus on cataract formation and other biological effects. The study contributed to early discussions about establishing safety standards for nonionizing radiation exposure. This represents foundational work in understanding microwave bioeffects during the early development of microwave technology.

Comments on Human Exposure to Nonionizing Radiant Energy - Potential Hazards and Safety Standards

L. Birenbaum · 1972

This 1972 research examined potential health hazards from microwave radiation exposure, with particular focus on cataract formation and the adequacy of existing safety standards. The study contributed to early understanding of how nonionizing radiation affects human health, specifically addressing concerns about microwave-induced eye damage that were emerging in occupational settings.

Environmental Aspects of Microwave Radiation

Donald I. McRee · 1972

This 1972 review examined the environmental health implications of microwave radiation, focusing on biological effects and dielectric properties of electromagnetic fields. The research explored how microwave frequencies interact with biological systems and their potential environmental consequences. This early environmental health assessment helped establish foundational understanding of microwave radiation's biological impacts.

BIOLOGICAL EFFECTS OF ELECTROMAGNETIC RADIATION – DESIGNATION OF PROJECT OFFICE

Department of the Navy, Bureau of Medicine and Surgery · 1971

The instruction designates a BUMED Project Office for Biological Effects of Electromagnetic Radiation. The project covers the entire electromagnetic spectrum from cosmic rays to extremely low frequency, with primary interest in microwave and extremely low frequency areas. The mission is to provide the Chief of the Bureau of Medicine and Surgery and the Operating Forces of the Navy, and other Services and agencies when requested, with information and research data concerning the biological effects of electromagnetic radiation.
