In a cohort of 340 police officers, six incident cases of testicular cancer occurred between 1979 and 1991 (O/E 6.9; p < 0.001). Occupational use of hand-held radar was reported as the only shared risk factor among the six cases, with routine close proximity …
Microwave radiation at 2.54 GHz was reported to induce lipid peroxidation in phosphatidylcholine liposomes, assessed via absorption spectra of conjugated dienes. The abstract notes a discussion of how this relates to previously observed microwave-enhanced lip…
Repeated microwave exposure (1 mW/cm2) inhibited the anaphylactic response in some guinea pigs and was accompanied by increased blood histamine, epinephrine, and norepinephrine. The increases were more pronounced in irradiated guinea pigs that died from anaph…

A single 30-min microwave exposure (80 mW/cm2, 2.45 GHz, continuous wave; SAR ~72 W/kg) or a matched radiant-energy thermal load (both raising core temperature ~3°C) decreased canalicular membrane permeability to sucrose but not to mannitol, and produced a ra…
In four rats tested in a cold environment, Friedman's test indicated significant differences among aspirin doses and saline control on operant responding reinforced by microwave radiation. Post hoc tests suggested a moderate aspirin dose increased responding,…
In this hospital-based case-control study (81 cases, 77 controls), reported residential proximity to multiple EMF-generating sources had odds ratios above 1. The highest reported associations were for living near high-voltage distribution lines (OR 2.63, 95% …

In Chinese hamster V79 cells exposed to a 50-Hz sinusoidal EMF at 2 G, no modification of mutation frequency (HGPRT- mutants) was observed. Survival/viability results were contrasting: plating 10^2 cells showed reduced colonies (about 50% after 10 days), whil…
Using workplace measurements (1,015 workplaces) and the job held longest in the 10 years before diagnosis, higher average daily mean EMF exposure was associated with increased odds of chronic lymphocytic leukemia (dose-response across three exposure levels: O…
In a worst-case scenario, eye heating was observed but was mainly attributed to conventional heating rather than microwave radiation. Significant microwave-related heating occurred only when increased scattered radiation was simulated by disabling safety cont…

After long-term exposure of rats to a 50-Hz, 30-mT magnetic field for 7 or 28 days, magnetic-field exposure did not influence sister-chromatid exchange frequencies or proliferation characteristics in cultured peripheral lymphocytes. Cyclophosphamide (positive…
Female lambs continuously exposed from 2 to 10 months of age beneath a 500-kV transmission line (mean electric field 6 kV/m; mean magnetic field 40 mG) showed no differences versus controls in nighttime melatonin secretion pattern (amplitude, phase, duration)…
Exposure to EMFs from personal computers, color TVs, microwave ovens, and cellular phones induced transient molecular abnormalities related to cancer markers and neurotransmitters at the EMF entry and exit areas on the body. Effects varied by source and inclu…
The paper proposes an empirical model to compute multiple potentially “active” AC/DC magnetic-field combinations as a function of DC magnetic field strength and to define an exposure rating system based on proximity of power-line AC frequencies (and harmonics…
The paper discusses fundamental principles of electromagnetic field radiation, including physical characteristics of electric and magnetic fields, everyday sources, detection/measurement methods, instrument considerations, and issues/misconceptions about shie…
The paper summarizes occupational power-frequency electric and magnetic field measurement data, noting that exposures are highly variable in space and time and that exposure distributions are strongly skewed, implying large sample sizes and multiple statistic…
The paper discusses questions in research on associations between EMF exposure and cancer and emphasizes the need for more accurate exposure assessment. It presents a molecular biological model suggesting EMF may have characteristics compatible with a cancer …
In ovariectomized female rats treated 1 hour/day for 4 months with 50 Hz pulsed magnetic fields, 30 Gauss maximum intensity slowed bone mass loss to within about 10%. With 70 Gauss maximum intensity, no significant bone mass loss was observed.
In two groups of 10 rats undergoing 70% jejunoileal resection, the group receiving EMF stimulation (43.20 gauss for 10 days) showed augmented mucosal adaptation in the proximal and distal remaining small intestine compared with no stimulation.
EMF stimulation significantly increased intestinal wound healing in normal rats at postoperative days 7 and 14. Dexamethasone significantly impaired healing (decreased TS and OH-P), and EMF stimulation significantly reversed this inhibitory effect.
