Microwave exposure (2450 MHz, 60 mW/g, CW) increased Na passive transport in rabbit erythrocytes only at membrane phase transition temperatures (Tc 17–19°C), and this effect was enhanced under relative hypoxia (pO2 ≤ 5 mm Hg). At Tc, exposure also induced she…
Exposure to 6000-MHz microwave radiation at 35 mW/cm2 during pregnancy resulted in significant differences in fetal weight, developmental milestones, behavioral test results, and organ/body weight ratios, indicating subtle long-term neurophysiologic alteratio…
Compared with sham irradiation (0 mW/cm2), exposure to 2450-MHz continuous-wave microwaves at 40 mW/cm2 (SAR 6.0 W/kg) for 100 min/day on gestation days 6–15 produced significantly lower mean fetal body weight (9% lower; p=0.0008) and significantly delayed st…
The review describes multiple cataractogenic stresses in humans, including radiation cataracts from X-irradiation, near UV radiation, and microwave radiation. It notes that oxidative stress is a common denominator of many changes in senile cataract and descri…
Human erythrocytes exposed to 2450 MHz microwave radiation (average SAR 0.4 W/kg) for 20 minutes showed temperature- and condition-dependent effects. Microwave exposure significantly decreased spontaneous hemolysis of untreated cells at 42°C (no effect at 37°…
Exposure to 2.45 GHz microwave radiation at 10 or 100 mW/g had no effect on mitochondrial respiration states or respiratory control index with succinate substrate. With glutamate substrate, 100 mW/g exposure increased states 2 and 4 and decreased respiratory …
Irradiated birds generally maintained their positions within the flock hierarchy (with one exception). Some irradiated birds appeared to have a change in their level of aggression after exposure.
Exposure to 915 MHz microwave radiation at SAR values of 0.05 and 1 mW/g caused a significant increase in calcium ion efflux from human neuroblastoma cells compared to controls. The increase at 0.05 mW/g required 16 Hz amplitude modulation, while the increase…
In rats exposed for 45 min to 2,450-MHz pulsed microwaves (1 mW/cm2; SAR 0.6 W/kg), microwave exposure did not significantly change the extent of pentobarbital-induced colonic temperature fall when exposure preceded pentobarbital injection, but recovery from …
Isolated frog hearts exposed to 2,450-MHz continuous-wave radiation at 2 and 8.55 W/kg showed an accelerated decrease in heart rate only in groups where heart rate was recorded using a 3-M KCl glass electrode or a metal wire in the Ringer's solution electrode…
Pregnant rats exposed throughout pregnancy to 6000-MHz microwave radiation (35 mW/cm2) showed no significant increase in maternal body temperature. Irradiated fetuses had slight but statistically significant growth retardation at term, and term maternal monoc…
In rabbits, local irradiation of exposed cerebral cortex with 2450 MHz microwaves (5–40 W) produced hyperemia and hyperoxia in the exposed zone, attributed to a hyperthermal effect. Irradiation of the medulla oblongata at low power not leading to hyperthermia…

The review states that microwave radiation exposures below maximal permissible levels present no measurable risk to the embryo, and that diagnostic ultrasound exposure is described as quite innocuous. For ionizing radiation, animal and human data are describe…
Across measured fetal parameters (body/brain weight; brain RNA, DNA, protein), values in radiated fetuses did not differ significantly from sham-exposed fetuses. No micrencephalous fetuses were identified in the radiation group using the stated regression cri…
In membrane-free acetylcholinesterase exposed in-field to 2,450-MHz pulsed microwave radiation, no significant changes in enzyme activity were observed across a range of power densities, pulse widths, repetition rates, and duty cycles.
Human blood specimens exposed to 2.45 GHz microwave radiation at specific energy absorption rates of 104 or 193 W/kg (below 36°C) showed chromosome damage that did not exceed control levels, including unstable chromosome/chromatid aberrations and sister chrom…
Pregnant mice exposed to 2450 MHz continuous-wave microwave radiation at an average power density of 30 mW/cm2 for 8 hr/day during gestation days 1–6 or 6–15 showed no changes in peripheral blood total or differential leukocyte counts on day 18 of pregnancy. …
Whole-body SAR decreased with increasing body weight/size, with a reported 12-fold lower whole-body SAR in 5 g pups compared with 320 g adults. Local SARs exceeded whole-body SARs: colon local SAR was slightly higher for 40–320 g animals and ~2.5× higher for …
In 1980, about 15% of mothers of live infants and 23% of mothers with stillbirths reported a medical X-ray procedure during pregnancy. About 34% of mothers in the 1980 National Natality Survey and 53% of mothers in the 1980 National Fetal Mortality Survey had…
A remote method to determine breathing frequency in unrestrained mice was described using a rectangular waveguide at 2450 MHz. Rhythmic changes in microwave power transmitted through the waveguide tracked inspiration/expiration due to changes in the mouse’s a…
