Repeated exposure to 2450 MHz microwaves at 40 mW/cm2 (described as whole-body microwave hyperthermia) was associated with fewer blastulas and more embryos at the 2–8 blastomer stage on gestation day 4, suggesting developmental delay. Exposure at 40 mW/cm2 du…

Adult male rats were exposed to 2880-MHz pulsed microwaves at various SARs and durations, with sham exposure and a 40°C hyperthermia comparison. Flame photometry suggested SAR thresholds for changes in salivary gland ions of 6.8 W/kg (Na+), 6.8 W/kg (K+), and…
In 50 animals examined 1, 10, 20, and 30 days after a single exposure to non-ionizing microwave radiation (12.6 cm wavelength; 400–500 mW/cm2), the authors report severe disturbance of glial neurons and cells with dystrophic processes throughout the spinal co…

Exposure to 2.45 GHz microwave radiation at 43 W/kg for 30 minutes did not significantly reduce post-implantation survival, indicating no mutagenic effect on male germ cells. However, pregnancy rates were significantly reduced during weeks 3 to 6 post-exposur…
Mice and rats chronically exposed to 2375 MHz microwave radiation for 1–3 months showed substantial changes in the cellular (T-system) immunity system. The abstract reports non-thermal intensity exposure and notes latent lesions that became apparent with func…

Embryos exposed continuously to 2.45 GHz CW microwave radiation (incident power density 5 mW/cm2; SAR 4.03 mW/g) showed significantly reduced sperm numbers and motility at 23 weeks of age (P ≤ 0.01). Fertility (percentage of fertile eggs) was significantly re…
A single case described momentary exposure of the right hand to microwave oven irradiation, resulting in transient paresthesias and a cold, pale hand that resolved spontaneously within 60 minutes without treatment. The report notes that even momentary exposur…
Exposure to 2.45 GHz microwaves at 44 W/kg for 30 minutes caused maximal decreases in sperm count and increased abnormal sperm morphology 2-4 weeks post-exposure. Reduced male fertility correlated with reduced pregnancy rate but less with pre-implantation sur…
In vitro exposure to extremely low frequency EMF (square waveforms) was associated with reduced mitogen-stimulated blastogenesis of human peripheral blood lymphocytes. PHA stimulation showed strong inhibition by [3H]thymidine incorporation; ConA-induced blast…
Daily gestational exposure to 2,450 MHz microwaves at 40 mW/cm2 (thermal) significantly inhibited embryonal and fetal development and increased intrafetal bleedings, resorptions, and fetal deaths. Pups of dams exposed for the whole gestation at thermal doses …
In offspring of rats prenatally exposed to 2450-MHz microwave radiation (20 mW/cm2), analyses found no significant malformations and no significant alterations in neonatal physiologic/reflex measures, body/organ weight ratios, or adult breeding results. Five …
In two 90-day experiments (0.5 and 5 mW/cm2), a statistically significant decrease in food consumption was observed only during the 5 mW/cm2 exposure (P<.01). Other measured variables, including body mass, blood-related measures, eye exams for cataracts, and …
Gestational exposure to 2.45 GHz continuous-wave radiation (average power density 10.3 mW/cm2) did not affect pregnancy rate or litter size, but pup weight was reduced. White blood cell numbers were lower in exposed male and female pups, and differential cell…
Both continuous wave and pulse modulated microwave radiation at comparable dose rates (5.8 and 6.7 mW/kg) equally reduced operant response rates and elevated body temperature by 0.5 to 1.0°C. At a lower dose rate (3.6 mW/kg), response rates during timeout wer…
Mice selected an average ambient temperature of 31°C without microwave exposure, and preferred Ta did not change until SAR at 2,450 MHz exceeded ~7.0 W/kg. During exposure with a temperature gradient, mice selected cooler Ta and kept breathing rate near basel…
No remarkable differences were observed between microwave-exposed and sham-irradiated control groups for the histologic or quantitative parameters examined. The study did not demonstrate a significant effect of 10 mW/cm2, 2,450 MHz exposure during embryonic, …
In preliminary work (24 rats), 20 mW/cm2 at 2450 MHz did not significantly increase maternal body temperature. In the main study (75 pregnant rats; 12 exposed, 4 sham, 59 environmental controls), no significant alterations were observed in maternal weight gai…
Turkey sperm exposed in vitro to 2.45-GHz microwave radiation for 30 minutes at SAR 10 or 50 mW/g, with temperature maintained at 25 or 40.5°C, showed no effect on fertilizing capacity under the experimental conditions.
Rats exposed to pulse-modulated 1.3 GHz microwave radiation (mean dose rate 6.3 mW/g) for 6 h/day for nine days showed no statistically significant differences versus sham controls in organ masses, daily sperm production, sperm morphology, or epididymal sperm…
In vitro exposure to 2450 MHz continuous-wave microwaves during stages of the microtubule polymerization cycle showed no change in baseline turbidity or light-scattering properties at 20 or 200 mW/g SAR. EGTA-induced polymerization and cold-induced depolymeri…
