Research Overview

  • -The science demonstrates a consistent pattern: 84% of studies examining electromagnetic field exposure and immune function have documented measurable effects.
  • -This isn't a fringe finding or isolated result.
  • -Across 521 peer-reviewed investigations, researchers have identified changes in immune cell activity, altered inflammatory responses, reduced antibody production, and shifts in white blood cell populations following EMF exposure.

The science demonstrates a consistent pattern: 84% of studies examining electromagnetic field exposure and immune function have documented measurable effects. This isn't a fringe finding or isolated result. Across 521 peer-reviewed investigations, researchers have identified changes in immune cell activity, altered inflammatory responses, reduced antibody production, and shifts in white blood cell populations following EMF exposure. Some studies show suppressed immune function-your body's defense system becoming less responsive-while others document hyperactivation, where immune cells overreact to normal stimuli.

In this case, we're talking about your immune system and electromagnetic fields-and the evidence demonstrates a consistent pattern that most people simply haven't heard about.

Importantly, many effects occur at exposure levels below those causing significant body temperature increases, with some studies showing responses at specific absorption rates as low as 0.14 W/kg.

THE EFFECT OF HYPERPYREXIA INDUCED BY RADIATION UPON THE LEUKOCYTE COUNT

William Bierman, M.D. · 1934

Researchers induced hyperpyrexia in 24 human subjects using 30 m radio waves, raising rectal temperature to 104° to 106° F. and maintaining it for 3 to 4 hours. White blood cells initially fell 25 to 30 per cent by the end of the first or second hour. By the third to fifth hour leukocyte counts rose to 80 per cent above baseline, reaching as high as 22,600, and immature forms such as myelocytes, metamyelocytes, premyelocytes, and myeloblasts appeared.

EXPERIMENTAL AND CLINICAL INVESTIGATIONS CONCERNING THE EFFECT OF ULTRASHORT ELECTRICAL WAVES ON INFLAMMATION

Erich Pflomm · 1931

Rats exposed to weak radiation were indistinguishable from non-radiated controls in size, behavior, and reproduction. Rats exposed to strong radiation showed depressed behavior, reduced growth, rough fur, and complete failure to reproduce over months of observation. Histology of heavily irradiated tumors revealed loss of tissue fluid, diffuse necrosis, expanded blood vessels, thrombosis, and very high leukocyte counts. Blood analyses of irradiated rabbits showed abnormal erythrocyte behavior and a strong leukocyte increase peaking at six hours after exposure.

Management of Rheumatic Disease with Diapulse Therapy

The study covered 94 patients. 86 of those patients achieved partial or complete symptomatic relief. Among 46 patients with before and after roentgenograms, observable absorption of calcium was seen in 42 cases. The authors concluded that sufficient evidence shows Diapulse PUHF energy is a valuable addition to the therapeutic armamentarium for rheumatic diseases.

RESEARCH INTO THE INFLUENCE OF HIGH FREQUENCY ELECTROMAGNETIC FIELD ON HUMAN BODY

HADUCH, S

The study was titled “Research into the influence of high frequency electromagnetic field on human body” and was conducted by Stanislaw Haduch and Stonislaw Baranski in 1960. Researchers examined peripheral blood by determining the number of erythrocytes and leukocytes and their percentage proportions. Exposed animals developed fever and died within a few days, with temperatures from 41.0 to 41.8°C.

SCIENTIFIC LITERATURE EVALUATION GROUP

Roger Budd, Przemyslaw Czerski, LeRoy W. Schroeder

Researchers infected African green monkey kidney cells with herpes simplex virus and exposed them to a pulsed electromagnetic field for varying periods up to 48 hours. After 48 hours, they counted viral plaques and measured plaque size. Two experiments found no statistically significant differences in plaque numbers between exposed and control cultures. An initial suggestion of larger plaques in longer exposures was not confirmed in a second experiment with more uniform cell monolayers. The authors concluded that the screening system did not detect a biological effect of the pulsed electromagnetic field, though the device has been shown to affect immune cell functions in other studies.

THE EFFECTS OF 9-GHZ PULSED MICROWAVES ON CIRCULATING ANTIBODY TITERS OF MICE

Unknown authors

Researchers immunized female CD-1 mice against Streptococcus pneumoniae type III and exposed them to 9-GHz pulsed microwaves at 10 mW/cm² for two hours daily over five days. The mean antibody titer in irradiated mice was significantly higher than in sham-irradiated mice (means 24 versus 7.88, p=0.0025). When challenged with virulent bacteria, mortality was similar between the two groups (47.2% versus 50%).

EFFECT OF LONG-TERM LOW-LEVEL MICROWAVE EXPOSURE ON DEVELOPMENT AND GROWTH OF CHEMICALLY /3,4-BENZOPYRENE AND DI-ETHYL-NITROSO-AMINE/ INDUCED NEOPLASMS

Unknown authors

The study used BALB/c mice and the chemical carcinogens 3,4-benzopyrene applied to skin and diethylnitrosamine injected intraperitoneally. Both carcinogens led to neoplasms with immunosuppression in the final stage of tumor growth. Exposure at 20 mW/cm2 caused earlier immunosuppression and earlier tumor appearance, while 5 mW/cm2 produced only slight insignificant differences.

INFLUENCE OF PULSED MICROWAVE RADIATION ON THE LYMPHOCYTES OF RATS

Unknown authors

Researchers exposed 20 young male rats to pulsed microwaves at 24.4 mW/cm² for seven weeks, five days per week, four hours per day. A significant drop in absolute lymphocyte count occurred from the fifth week of irradiation and persisted until ten weeks after exposure ended. The percentage of large lymphocytes remained relatively higher in irradiated rats throughout most of the exposure period. No significant changes were found in nucleolar coefficient or nucleoli types except a transient drop in the nucleolar coefficient during the first week. In a second experiment, adult rats were exposed to 1 mW/cm² pulsed microwaves for 14 weeks and no significant changes were found in lymphocyte counts or nucleolar characteristics.

KINETICS AND MECHANISMS OF THE INDUCTION OF AN INCREASE IN COMPLEMENT RECEPTOR POSITIVE (CR+) MOUSE SPLEEN CELLS FOLLOWING A SINGLE EXPOSURE TO 2450 MHZ MICROWAVES

Unknown authors

Researchers exposed mice to 2450 MHz microwaves at 0.6 watts forward power with an absorbed dose of 12 to 15 mW/g and measured CR+ spleen cells on days 3 and 6. A minimum 15-minute exposure induced a significant increase by day 3 that peaked at day 6, and a maximal increase occurred after 45 minutes. The increase did not require mature T cells and only occurred in mice older than 6 to 8 weeks, indicating a maturation prerequisite. The effect was not mediated by LPS, and susceptibility mapped to the H-2k haplotype.

Immune SystemNo Effects Found

PRIMARY IMMUNE RESPONSE OF MICE EXPOSED TO CONTINUOUS OR PULSED WAVE 425-MHZ RADIOFREQUENCY RADIATION

Unknown authors

Female BALB/c mice were exposed to continuous-wave or pulsed-wave 425-MHz radiation in a TEM transmission line for one hour per day over five consecutive days, with sham-exposed controls. Continuous-wave exposures used power densities of 39, 10, and 2.5 mW/cm², while pulsed-wave exposures used 9, 2.5, and 0.63 mW/cm² with a 1 msec pulse at 250 pulses per second. Mice exposed to pulsed-wave at 9.0 mW/cm² showed increased colonic temperature, but continuous-wave at 39 mW/cm² did not, and peripheral blood cell counts were unchanged. The primary immune response to sheep red blood cells, measured by plaque-forming cell and hemagglutination assays, did not differ between sham and exposed groups or between continuous-wave and pulsed-wave exposures.
