All microwave irradiation protocols (2,450 MHz at 5, 10, or 15 mW/cm2; described as athermal or subthermal) significantly accelerated development of benzopyrene-induced skin cancer and shortened lifespan of tumor-bearing mice versus sham-irradiated controls. …
Male CBA/J mice injected with Salmonella typhimurium LPS and then exposed to 2450 MHz continuous-wave microwaves showed a significant decrease in the LPS dose required to kill 50% of the mice at 20 and 30 mW/cm2 (2-hour exposure), compared with sham-irradiate…
In mice, the ambient-temperature threshold for increasing evaporative water loss was between 30 and 33°C. During 90-min 2450-MHz exposure, an SAR in excess of 29 W/kg was required to increase heat loss; for SAR 29–44 W/kg, about 65% of absorbed heat was dissi…
Two men with accidental acute X-band microwave exposure were followed for 12 months and developed similar psychological symptoms (emotional lability, irritability, headaches, insomnia). Several months after exposure, hypertension was diagnosed in both; no org…
In irradiated embryos, slight developmental retardation was observed in cerebellar cortices across several morphological parameters, along with lower body and brain weights. In eight-week-old quail, no significant differences were noted between irradiated and…
In experiments on 478 white rats, repeated exposure to low doses of nonionizing microwave radiation was reported to alter structural and functional bases regulating cell metabolism and to exert a damaging action on delicate cell structures, with changes descr…

The review covers RF (300 kHz–300 MHz) and microwave (300 MHz–300 GHz) exposures. Animal investigations are described as showing pathophysiological manifestations at certain power densities over minutes to hours, with effects variably associated with measurab…
SAR values between 3.1 and 6.7 mW/g were reported for 425 MHz exposure. No differences in weight were observed between irradiated and sham-irradiated rats, and no consistent changes were seen in peripheral blood counts. Significant increases in mitogen-stimul…
Rhesus monkeys exposed to 1.29 GHz microwaves at incident power densities of 20, 28, and 38 mW/cm2 (SARs 2.1, 3.0, and 4.1 W/kg) showed average rectal temperature increases of 0.5, 0.7, and 1.7 C, respectively. No changes in thyroxine (T4) or growth hormone (…
Turkey sperm exposed for 30 minutes to 2.45 GHz microwave radiation at SAR levels of 1, 10, or 50 mW/g (temperature maintained at 40.0 ± 0.5°C) showed no significant changes in viability, abnormal sperm percentage, or release of LDH and GOT enzymes under the …
At 22°C and 37°C, a 30-min exposure to 2.45-GHz continuous-wave microwave radiation at 2 mW/g or 10 mW/g did not alter the rate of atrial contraction compared with sham-exposed controls. No inotropic effects were observed at any exposure level.
Heat stress (38°C, 62% RH for 3 h on day 2) caused stunted embryo development. No remarkable effect of 2.45-GHz microwave exposure (9 or 19 mW/cm2 for 3 h on day 2 or 3) was found on development of preimplantation embryos.
No shift of the phase transition was found during continuous-wave 1.0-GHz microwave exposure at specific absorption rates between 1 and 30 W/kg. No statistically significant differences were observed between exposed and control samples when temperature was ma…
Theoretical modeling showed that DNA in aqueous solution can directly absorb microwave energy via coupling to longitudinal acoustic vibration modes, with water damping broadening but not reducing total absorption. This supports experimental observations of an…
Male CBA/J mice exposed to 2,450-MHz microwaves at ambient 30 C received heat loads of 08 J d7g^-1 at SARs of 47 or 93 W d7kg^-1 while EHL was monitored. The threshold heat load for increased EHL was 10.5 J d7g^-1 at 47 W d7kg^-1 and 5.2 J d7g^-1 at 93 W d7…
Describes two alternate nonrestraining waveguide chamber designs and a positioning device for use with microwave generators. The chambers are designed for use with 2450 MHz microwave energy for rapid killing of small rodents.
