The study established early safety guidelines for static magnetic field exposure.
C.A.L. Bassett et al. · 1978
Researchers used pulsed electromagnetic fields to treat 106 patients with bone fractures that wouldn't heal naturally (pseudarthroses).

This demonstrates that carefully controlled electromagnetic fields can stimulate biological healing processes in humans.
Michaelson SM · 1978
This 1978 case study documented a postmastectomy patient who experienced sensitivity to microwave oven radiation in the area where surgery had been performed.

Robert D. Tucker, Otto H. Schmitt · 1978
Researchers tested over 200 people in more than 30,000 trials to see if humans can consciously detect moderate-strength 60 Hz magnetic fields (7.5-15 gauss). Using a specially designed isolation chamber to eliminate false clues, they found no evidence that people can sense these electromagnetic fields, even with biofeedback training.
Paul Brodeur · 1978
This 1978 article by Paul Brodeur documented growing public concern and resistance to microwave radiation exposure from various sources. The piece examined how communities were beginning to organize and push back against microwave installations and policies that ignored potential health risks. This represents an early example of grassroots advocacy challenging official assurances about microwave safety.
Paul Brodeur · 1978
This 1978 analysis by Paul Brodeur examined how government agencies and industry responded to growing concerns about microwave radiation health effects by blaming media coverage rather than addressing the science. The review covered controversial cases including the Moscow Embassy microwave bombardment and PAVE PAWS radar systems, highlighting patterns of deflecting responsibility when health questions arose.
Huai Chiang, K-C Yee · 1978
In 1978, Chinese researchers conducted health studies on microwave radiation exposure and used their findings to recommend national safety standards for microwave exposure. This represents one of the earliest systematic attempts by a government to establish protective limits based on actual health research rather than just thermal effects.
Howard I. Bassen et al. · 1978
This 1978 government report examined microwave radiation leakage from diathermy machines used in medical treatments. Researchers measured how much microwave energy escaped from these therapeutic devices when used on both human patients and phantom test models. The study was part of federal efforts to assess potential exposure risks from medical microwave equipment.
M. H. Repacholi · 1978
This 1978 Canadian government paper proposed the first national exposure limits for microwave and radiofrequency radiation, recommending 1 mW/cm² (10 W/m²) for continuous human exposure. The authors argued this limit would protect both workers and the general public while remaining technically feasible for industry compliance.
R.M. Albrecht, E. Landau · 1978
This 1979 epidemiological assessment examined microwave radiation exposure patterns across different applications including communications, industrial uses, home ovens, and medical diathermy. The study highlighted significant discrepancies between Eastern and Western exposure standards, with Eastern European countries reporting adverse health effects at much lower levels than Western safety limits allowed.

This 1978 research examined microwave radiation as an invisible form of air pollution, focusing on sources like radar systems and their potential public health implications. The study addressed electromagnetic pollution during an era when microwave technology was rapidly expanding but health effects were poorly understood. This work helped establish early awareness of microwave radiation as an environmental health concern.

Researchers tested two microwave diathermy applicators used for medical heating therapy on tissue models and human subjects.

This 1978 study discovered that the human head acts like an antenna, resonating at 350 MHz microwave frequency and absorbing 3 times more radiation than previously thought. Researchers found that the whole body affects head absorption patterns, making isolated head models inaccurate for safety calculations.
QUIRINO BALZANO, OSCAR GARAY, FRANCIS R. STEEL · 1978
Researchers tested how much radiofrequency energy from 800 MHz portable radio transmitters gets absorbed into simulated human tissue, particularly near the head. They found that different antenna designs create "hot spots" about 1 inch below the temporal bone, with some antennas exposing the eye area to higher energy levels. The temperature increases were small enough that researchers concluded normal radio use shouldn't cause thermal tissue damage.
