Researchers exposed isolated chicken brain tissue to radiofrequency fields modulated at brain wave frequencies and found increased calcium release from cells. The calcium response depended on specific chemical conditions in the surrounding solution, particularly bicarbonate and hydrogen ion levels. This suggests that weak electromagnetic fields can trigger biological responses in brain tissue through specific binding sites.

This 1978 review examined what was known about microwave radiation's biological effects on humans and animals. The author found significant gaps in scientific understanding and major limitations in existing research methods. The review called for more rigorous, well-documented studies across different exposure levels to better understand microwave health risks.

This 1978 study tested electromagnetic rodent control devices in poultry facilities and found they successfully reduced rat and mouse populations. The devices caused neurological dysfunction in rodents, leading to distorted eating patterns, lethargy, reduced reproduction, and eventually death. When the electromagnetic field was removed, surviving rodents recovered.

Researchers exposed Candida albicans yeast cells to 72-74 GHz microwave radiation, comparing continuous waves to square-modulated signals. They found that modulated microwaves reduced the number of viable cells more than continuous waves at the same power level. This suggests that how microwave energy is delivered (pulsed vs. continuous) affects biological impact.

Researchers tested how VHF portable radio transmitters heat human tissue using realistic phantom models of the head and body. They found that despite high field measurements near the antenna, actual tissue heating was minimal (less than 0.1°C) because the radio waves don't penetrate effectively into biological tissue. The only health risk occurs if someone places the antenna tip directly against their eye.
Quirino Balzano, Oscar Garay, Frances R. Steel · 1978
Researchers tested how VHF portable radio transmitters heat human tissue using realistic phantom models of muscle, fat, bone, and brain. They found that actual tissue heating was much lower than expected because the radio's antenna creates static fields that collapse at the air-body interface due to human tissue's electrical properties. This discovery helped explain why early field measurements overestimated potential heating effects.

Researchers tested how heat and X-ray radiation affected the survival of three different cell types, including human brain tumor cells and Chinese hamster ovary cells. They found no correlation between how sensitive cells were to heat versus radiation damage. Cells that were highly sensitive to one type of damage weren't necessarily sensitive to the other.

Scientists exposed mice to 2.5 GHz microwave radiation and found it dramatically altered how immune cells moved through the body. The radiation caused immune cells to get trapped in lungs, prevented them from reaching the spleen, and forced more cells into bone marrow than normal. This suggests microwave exposure disrupts the immune system's ability to function properly.

Researchers exposed mice to 2.5 GHz microwave radiation at high intensity (30 mW/cm²) for 30 minutes, then tested whether their blood serum and immune cells could better fight cancer. The study found that serum and lymphocytes from microwave-exposed mice showed enhanced ability to destroy transplanted tumor cells. This suggests microwave exposure may boost certain immune system functions.
