In the West Midlands (England) during 1969–76, suicide locations were significantly correlated with measured power-frequency magnetic field strength, with more suicides occurring at locations with high magnetic field strength.
After 1 hour of continuous-wave 2450 MHz exposure (energy absorption rate 15.5 mW/g), membrane electrical resistance and membrane time constant decreased by 22% and 26%, respectively. EDTA injection into the cell blocked the change in membrane resistance, whi…
Two cases of high-frequency electromagnetic radiation exposure are presented: one industrial high-density radiofrequency field exposure associated with necrosis of the entire hand and wrist and systemic effects, and one excessive microwave exposure from a mal…
Using circular dichroism spectroscopy, high-level 2450 MHz microwave irradiation (SAR 600 mW/g) was associated with decreases in alpha-helical conformation in erythrocyte ghost proteins. Isolated spectrin (bands 1 and 2) was reported to be more sensitive than…
Male C3H mice exposed for 30 min to 2.45 GHz microwave radiation showed testicular damage measured 6 days later, ranging from spermatocyte depletion to extensive necrosis of the germinal epithelium. Implanted probes indicated a threshold for spermatocyte depl…
Exposure to 30 mW/cm2 on gestation days 1–6 was associated with fewer implantation sites per litter and reduced fetal weight. Exposure to 30 mW/cm2 on gestation days 6–15 produced a slight but statistically significant increase in malformed fetuses (predomina…
In vegetative cells of P. aeruginosa and S. aureus exposed to low-intensity 2,450 MHz radiation (1 joule min-1 ml-1) for 16 h, minor structural changes in the cell envelope were reported, associated with altered preservative sensitivity. No alteration of spec…
Humoral immune measures (anti-CRBC antibody, IgM, IgG at 0, 4, and 7 days postimmunization) were not significantly different between exposed and control quail. Cell-mediated immune response to phytohemagglutinin-P was reduced in exposed females but not expose…
A modified thermoregulatory model incorporating hypothalamic hot spots from microwaves suggested hypothalamus temperature does not increase drastically until energy deposition exceeds ~50 mW/g. At 10 mW/g in the hypothalamus, predicted skin blood flow increas…
Cell ultrastructure was unaffected after 1 hour of exposure at 41.8 or 74.0 GHz (average power densities 320 or 450 mW/cm^2) when monolayer temperature was maintained at ~37.2°C with recirculation cooling or did not exceed 42°C without cooling. Morphological/…
At 1.5 mW/kg, no differences in operant responding between control and irradiated rats were observed. At 3.6 mW/kg, no effect on cued responding but a transient increase in extinction rate of noncued responding occurred. At 6.7 mW/kg, slight reduction in cued…
Low power, pulsed microwave exposure induced a significant increase in local cerebral blood flow in the brain of the conscious rat. The authors state that prior studies on microwave-induced changes in brain vascular permeability should be re-evaluated in ligh…
Across 15–40°C, Arrhenius-type temperature profile plots were linear and showed no difference between microwave-exposed and control samples. Exposure-duration measurements at 23°C also showed no difference between exposed and control samples, except for a sma…
Sonicated egg phosphatidylcholine vesicles loaded with 24Na+ were exposed to frequency-modulated microwaves (3 Hz) in the 2350–2550 MHz range at 20 mW, or to 2450 MHz continuous-wave microwaves at 80 mW. Leakage of 24Na+ measured for up to 19 hours showed no …
Direct continuous-wave 2.45 GHz irradiation of the exposed myocardium for 5 h at SAR 30 mW/g did not influence mean arterial blood pressure, cardiac output, heart rate, plasma or myocardial creatine phosphokinase, or S-T segment in cats with or without myocar…
In vitro exposure of hepatic lysosomes to 2450 MHz CW microwave radiation at 10 or 100 mW/g for 60 minutes during retinol treatment had no effect on release of beta-glucuronidase, cathepsin D, or acid phosphatase. Pre-irradiation (40 min) followed by 20 min r…
Instrumentation was developed to monitor fluorescence in erythrocyte ghost membranes before/during/after 2450 MHz continuous-wave microwave exposure in a temperature-controlled waveguide. At reported specific absorption rates of 10 and 200 mW/g, microwave exp…
Frozen cefoxitin sodium admixtures thawed by microwave radiation showed no significant changes in drug concentration, no visible appearance changes, and only minimal pH changes before vs after the freeze-thaw process.
BHK-21/C13 monolayer cultures were exposed with minimal heating (≤0.1°C) across 202 closely spaced frequencies in the 38–48 GHz and 65–75 GHz ranges at average power densities of 292 and 177 mW/cm2. No changes in protein synthesis were observed, and the study…
Rat cerebral tissue exposed in vitro to pulsed microwave radiation (1 GHz) at low pulse repetition frequencies (16 or 32 Hz) and average power densities ranging from 0.5 to 15 mW/cm2 showed no alteration in 45Ca2+ efflux compared with controls.
