Among 63 workers occupationally exposed to 50 Hz electromagnetic fields at transforming/distributing stations, an increased risk of electrocardiographic disturbances was reported compared with 42 non-exposed controls. Under exposure to electric fields observe…

After 30 minutes of in vivo exposure of white male rats to a constant static magnetic field (SMF) of 0.2 T, dehydration was detected in brain, kidney, and liver tissues. Ouabain binding at 5×10^-9 M decreased in brain, heart, spleen, and liver tissues and inc…

In telephone interviews of 40 respondents, participants described unpleasant sensations (e.g., burning feeling or dull ache) mainly in temporal, occipital, or auricular areas that often began minutes after starting a call and usually resolved within an hour a…
Two patients developed symptomatic AV block several months after slow pathway radiofrequency ablation for AVNRT, requiring permanent pacemaker implantation. Both had multiple 24-hour Holter recordings before the procedure with no evidence of intermittent or p…
Compared with non-occupationally exposed controls, workers occupationally exposed to radiofrequency EMF showed significantly lower amplitudes of diurnal rhythms of blood pressure and heart rate (P < 0.01) and an earlier acrophase (1100–1200 h; P < 0.05). Chan…
Suppression of GJIC depended on magnetic flux density: 0.05–0.4 mT for 24 hours did not inhibit GJIC, while 0.8 and 1.6 mT did. At 0.8 mT, 5 minutes had no effect, 1 hour inhibited GJIC, and 24 hours showed the most apparent inhibition; no amplitude window ef…

The article argues there is reason to believe headaches reported with hand-held cellular telephone use are real and may be due to phone emissions, citing prior reports of headaches with low-intensity microwave exposure and evidence that such exposure can affe…
Workers occupationally exposed to microwave radiation showed increased IgG and IgA concentrations, increased lymphocyte and T8 lymphocyte counts, decreased NK cell counts, and a lower T-helper/T-suppressor ratio. The abstract states these immune changes had n…

The investigators report that pulsed high-frequency electromagnetic fields from mobile phones altered distinct aspects of the brain’s electrical response to acoustic stimuli. Differences were observed for induced (but not evoked) brain activity during exposur…
In 22 rabbits, pulsed microwave irradiation influenced extracellular activity of individual cortical nerve cells in sensorimotor and occipital areas. Responses included either increased or decreased discharge frequency, related to the initial background disch…

Rats exposed for 8 months to 50 Hz EMF at 5 µT–1 kV/m or 100 µT–5 kV/m showed no pathological changes in growth rate, tissue morphology/histology (liver, heart, mesenteric lymph nodes, testes, bone marrow), or serum chemistry. Norepinephrine levels increased …
In SCL II cells, 48-h and 72-h continuous exposure to a 50 Hz magnetic field at 0.8 and 1.0 mT produced statistically significant increases in micronucleus frequency and apoptosis. In AFC cells, exposures across 0.1–1.0 mT and 24–72 h showed no statistically …
Across five strains tested on agar plates over a broad range of field conditions, no effect on population motility was demonstrated, and exposure period, cell density, and cell-cycle position did not alter susceptibility. After at least a month of preincubati…
At 5 G (12 experiments), EMF-exposed cultures showed a significant delay in phage yield 45–65 minutes after inoculation compared with controls, but the final phage concentration was not altered. At 25 G (N=5), results suggested impeded phage replication and i…
Exposure of DT40 lymphoma B-cells to low energy electromagnetic fields was associated with activation of PLC-gamma2 and increased inositol phospholipid turnover. EMF-induced PLC-gamma2 activation depended on BTK: BTK-deficient cells did not show enhanced PLC-…
Electromagnetic fields with power density 0.4 to 10 mW/cm2 were reported to influence memory formation (imprinting) in chicks. The authors report the possibility of "fixing" modulated EMF information in the embryonic brain during the natal period with conserv…

Across various appliance exposures, some odds ratios were above 1.0 and others below 1.0. For electric blanket use by the child before diagnosis, adjusted ORs were 2.2 (95% CI 0.7–6.4) for leukemia, 1.6 (0.4–7.1) for CNS cancers, and 2.4 (1.0–6.1) for other s…
Human amniotic fluid cells exposed to 50 Hz, 1 mT magnetic fields showed statistically significant increases in micronucleus frequency under some exposure configurations: after 72 h vertical exposure in the Merritt-coil system, and after 24/48/72 h horizontal…
Continuous EMF exposure at 2 G enhanced proliferation in two prostate and three endometrial cancer cell lines, and in only one ovarian cancer cell line, compared with sham controls. EMF increased metabolic activity within 96 h and increased absolute cell numb…
Exposure of normal human skin fibroblasts to a 20 Hz, 7–8 mT electromagnetic field induced terminal differentiation within 14 days with 12 h/day exposure. The induction of terminal differentiation was reported to most likely not involve changes in c-myc prote…
