O. P. Gandhi · 1974
This 1974 study measured how radiofrequency radiation is absorbed by brain-like models and laboratory animals up to 4000 MHz. Researchers found that absorption increased dramatically (more than 10 times higher) when the radiation frequency matched the body's natural resonance, particularly when waves were aligned with the body's length.
S. K. Ghosh, A. M. Muc, D. H. Jagdyer, M. P. Diotte · 1974
This 1973 paper proposed creating standardized warning signs for microwave radiation exposure, similar to those used for ionizing radiation. The author recognized that microwave devices were rapidly increasing and exposing workers, the general public, and vulnerable groups like pacemaker wearers to potential health risks. The proposal aimed to reduce exposure through clear visual warnings that would communicate both the type and level of radiation present.

Researchers exposed human cancer cells and normal cells to microwave radiation between 76-86 GHz and found that cancer cells transmitted the microwaves differently than healthy cells. This 1974 study demonstrated that extremely high-frequency microwaves could distinguish between malignant and normal human tissue in laboratory cultures. The findings suggest cancer cells have unique electromagnetic properties that make them respond differently to microwave energy.

Researchers measured electrostatic charges on mice and rats, finding they produce electric fields averaging 200 V/m around their bodies. The study revealed that as animal population density increases, their activity levels decrease due to stronger combined electric fields from body contact and rubbing. Animals housed in Faraday cages (which block external electric fields) could tolerate higher population densities than those exposed to normal atmospheric conditions.
