Key Finding: 93% of 2,429 primary studies on whole body / general found biological effects from EMF exposure.

Of 2,429 studies examining whole body / general, 93% found measurable biological effects from EMF exposure.

Lowest Documented Effect

Research Overview

  • -When 95% of nearly 3,800 peer-reviewed studies document biological effects from electromagnetic field (EMF) exposure, we're looking at a weight of evidence that demands attention.
  • -This isn't fringe science or industry speculation-it's the consistent finding across independent research examining how radiofrequency radiation, extremely low frequency fields, and other non-ionizing EMF sources interact with human physiology.
  • -The question isn't whether effects occur, but which ones matter most to you and your family.

When 95% of nearly 3,800 peer-reviewed studies document biological effects from electromagnetic field (EMF) exposure, we're looking at a weight of evidence that demands attention. This isn't fringe science or industry speculation-it's the consistent finding across independent research examining how radiofrequency radiation, extremely low frequency fields, and other non-ionizing EMF sources interact with human physiology. The question isn't whether effects occur, but which ones matter most to you and your family. The documented effects span multiple biological systems.

That's what the evidence shows across the 3,798 studies in our whole body research collection: 3,591 of them identified biological changes in response to electromagnetic field exposure.

Research on chicken embryos exposed to both ELF and RF radiation demonstrated 27% less protective protein production after repeated exposures, indicating compromised cellular defense mechanisms.

THE EFFECT OF MICROWAVES ON BONE AND BONE MARROW AND ON ADJACENT TISSUES

Joseph P. Engel et al. · 1950

Researchers exposed anesthetized and trained dogs to microwave diathermy at 2,450 megacycles per second and measured temperature changes in tibial cortex, marrow, muscle, and subcutaneous tissue. For subcutaneously located bone, 30 minutes at 65 watts raised tibial cortex temperature by 5.0 degrees (C.) and marrow by 3.4 degrees (C.). For submuscularly located bone, the same exposure raised cortex by 3.8 degrees (C.) and marrow by 3.0 degrees (C.). A rectangular director allowed higher temperatures in subcutaneously located bone without excessively heating adjacent soft tissue. An impedance-matching transformer increased tissue temperature rises by approximately 300 per cent.

The Survival of Bacteria in High-Frequency Electric Fields

S. E. Jacobs, Margaret J. Thornley, P. Maurice · 1950

Researchers exposed various bacteria, principally Bacterium coli and Staphylococcus aureus, to high-frequency electric fields at 1-65 Mc/s with external electrodes while preventing lethal temperature rise. They used a low-powered variable-frequency generator (1-710 Mc/s) and a high-powered 44 Mc/s diathermy unit. Bacterial survival was judged by viable plate counts using duplicate samples. No significant mortality occurred in any experiment, even at high voltage gradients. The results consistently failed to confirm Fleming's 1944 report of high mortality.

TESTICULAR TEMPERATURE IN MAN

Herbert F. Newman, Seymour F. Wilhelm · 1950

Researchers measured testicular temperatures in 28 volunteers using tissue thermocouples inserted through the scrotal skin. Testicular temperatures were usually lower than rectal temperatures and changed with environmental temperature. Inguinal canals were warmer than the testes in most anesthetized men (average 2.7°F) and warmer than scrotal cavities in all cases (average 3.6°F).

A Comparative Study of the Temperature Changes Produced by Various Thermogenic Agents

Alma J. Murphy, W. D. Paul, H. M. Hines · 1950

Greater temperature increases occurred in superficial tissues in 247 of 266 experiments, while the least increase was at the 3 cm depth in 240 of 266 experiments. The greatest temperature rise in living tissue occurred during the first ten minutes of irradiation, and dead tissue showed greater temperature increases than living tissue for all wavelengths. After irradiation, living tissue temperatures tended to equalize across all measured depths, while only shorter wavelengths left the surface warmer than deeper tissue.

Dielectric Properties of the Human Body for Wave-lengths in the 1-10 cm. Range

T. S. England · 1950

Researchers extended earlier dielectric measurements at 3-18-cm. wavelength to 1-27-cm. and 10-0-cm. wavelengths using surgical tissue specimens. Absorption and phase constants were recorded for each tissue in a waveguide, with measurement accuracies of +10 per cent in absorption and +5 per cent in phase at 1-27-cm., and +5 per cent in absorption and +2 per cent in phase at 10-0-cm. Most tissues behaved like water, fat and bone were relatively transparent, and malignant and normal tissues did not differ significantly.

DIELECTRIC PROPERTIES OF TISSUES IMPORTANT IN MICROWAVE DIATHERMY

J. F. HERRICK, D. G. JELATIS · 1950

The study measured dielectric constant and loss of freshly excised tissues including liver, muscle, fat, bone, and bone marrow. The researchers used a microwave dielectrometer they designed and built for the measurements. They also presented dielectric properties of certain body fluids and designed a transformer to improve microwave power transfer into muscle.

FAQs: EMF & Whole Body / General

When 95% of nearly 3,800 peer-reviewed studies document biological effects from electromagnetic field (EMF) exposure, we're looking at a weight of evidence that demands attention. This isn't fringe science or industry speculation-it's the consistent finding across independent research examining how radiofrequency radiation, extremely low frequency fields, and other non-ionizing EMF sources interact with human physiology.
The SYB Research Database includes 2,429 peer-reviewed studies examining the relationship between electromagnetic field exposure and whole body / general. These studies have been conducted by researchers worldwide and published in scientific journals. The research spans multiple decades and includes various types of EMF sources including cell phones, WiFi, power lines, and other common sources of electromagnetic radiation.
93% of the 2,429 studies examining whole body / general found measurable biological effects from EMF exposure. This means that 2257 studies documented observable changes in biological systems when exposed to electromagnetic fields. The remaining 7% either found no significant effects or had inconclusive results, which is typical in scientific research where study design and exposure parameters vary.
