Erich Pflomm · 1931
This 1934 German study investigated how ultrashort electrical waves (early radio frequency radiation) affected inflammatory processes in laboratory animals. The research examined both experimental and clinical applications, exploring whether these electromagnetic fields could be used therapeutically to treat inflammation. This represents some of the earliest scientific work documenting biological effects from RF radiation exposure.

This study investigated how a single exposure to 2450 MHz microwave radiation affects immune cells in mouse spleens, specifically tracking changes in complement receptor positive (CR+) cells. The research examined the timing and biological mechanisms behind these immune system changes. The 2450 MHz frequency is the same used in microwave ovens and some WiFi devices.

This technical report examined how radio-frequency radiation affects three important biological molecules: gamma globulin (immune system protein), acetylcholinesterase (nerve function enzyme), and chymotrypsin (digestive enzyme). The research investigated whether RF exposure could alter these critical proteins that regulate immune response, nervous system function, and protein digestion.

This mouse study investigated how microwave radiation exposure affects immune system cells in the spleen, specifically looking at lymphoid cells that carry complement receptors. The researchers found that microwave exposure increased the frequency of these immune cells, suggesting that microwave radiation can alter immune system function at the cellular level.

This Southern Medical Journal study examined Diapulse therapy, which uses pulsed high-frequency (PUHF) electromagnetic energy to treat rheumatic diseases like arthritis. The research investigated whether this specific RF electromagnetic therapy could provide therapeutic benefits for inflammatory joint conditions. This represents early medical exploration of using controlled electromagnetic fields as a treatment modality.

This NASA technical report investigated how high-frequency electromagnetic fields affect the human body, with particular focus on white blood cells (leukocytes) and neutrophil granulocytes. The research examined biological responses to radiofrequency radiation exposure, contributing to our understanding of how EMF affects immune system components.

Researchers exposed male rats to 1.29 GHz microwave radiation at 15 mW/cm² for 90 minutes and measured stress hormone levels in their blood. The exposed rats showed dramatically elevated corticosterone (stress hormone) levels that were 6-8 times higher than unexposed rats after 75 minutes. This study demonstrates that microwave radiation can trigger significant stress responses in the body at frequencies close to those used by cell phones.

Researchers exposed pregnant rats and their offspring to 100-MHz radiofrequency radiation for months, finding no effects on growth, immune function, or blood counts. However, the study revealed significant changes in brain acetylcholinesterase activity, an enzyme critical for nerve signal transmission.

Researchers exposed animal organs to low-frequency electromagnetic fields (50-100 Hz) and found significant physiological changes. The study documented alterations in blood chemistry, thyroid and adrenal gland activity, phosphorus metabolism, kidney function, and immune system response. These findings demonstrate that power-line frequency EMF can measurably affect multiple organ systems in animals.

Researchers exposed dogs' thyroid glands to 2450 MHz microwave radiation (the same frequency used in microwave ovens) and found changes in thyroxine hormone production. The study concluded these effects were caused by tissue heating rather than non-thermal biological mechanisms. This demonstrates that microwave radiation can disrupt normal thyroid function through thermal effects.

This technical report by Roger Budd evaluated scientific literature on how RF and microwave radiation affects the immune system and cell membranes. The study used dielectric relaxation spectroscopy to examine cellular responses. The evaluation found mixed effects, suggesting some biological impacts occur but results vary across studies.

Researchers exposed mice to 9 GHz pulsed microwaves at 10 mW/cm² for 2 hours daily over 5 days and found significantly increased antibody production. However, despite higher antibody levels, the microwave-exposed mice died at the same rate as unexposed mice when challenged with a deadly bacterial infection.

Researchers exposed mice to 2450 MHz microwave radiation (similar to microwave ovens) for up to 4 months, then treated them with cancer-causing chemicals to see if the radiation affected tumor development. The study examined whether long-term microwave exposure changes immune system function in ways that could influence cancer risk.

Scientists exposed rats to pulsed microwave radiation at two different power levels for seven weeks to study effects on blood cells. At the higher power level (24.4 mW/cm²), white blood cell counts dropped significantly during the second half of exposure. At the lower power level (1 mW/cm²), no blood cell changes occurred.

This conference paper examined biological changes in Swiss mice exposed to microwave radiation, focusing on effects to nervous system function and immune responses. The research investigated how microwave irradiation altered normal biological processes, including nerve conduction and immune system activity.

This research from the New England Institute for Medical Research examined how radiofrequency (RF) fields affect immune system function, specifically studying phagocytic activity (the ability of immune cells to engulf harmful particles) and the reticuloendothelial system. The study also investigated the 'pearl-chain phenomenon,' where biological materials align in specific patterns under electromagnetic field exposure.

Researchers exposed mice to 2450 MHz microwave radiation (the same frequency used in microwave ovens and WiFi) and found it significantly increased immune cells in their spleens.

Scientists studied how microwave hyperthermia (heat treatment) used in cancer therapy affects the immune system. They found that immune cell reactions change dramatically depending on temperature - cells are stimulated at 39-41°C but inhibited at 42-44°C. This reveals that microwave heating has complex effects on immune function that vary with temperature.
