In rats and rabbits exposed to 2375 +/- 50 MHz in absorbant chambers, microwave radiation at 10, 50, and 500 µW/cm2 for 30 days (7 hr/day) was associated with changes in bioelectric brain activity and behavioral, immunological, and cytochemical reactions. At 10 and 50 µW/cm2, electric brain activity was reported to be stimulated at the initial stage of irradiation, while at 500 µW/cm2 it was reported to be suppressed (increase of slow, high-amplitude delta-waves). At 500 µW/cm2, decreases in work capacity, unconditioned feeding stimulus value, investigating activity, electronic irradiation threshold, and inhibition of cellular and humoral immunity were observed.

Homes of children who developed cancer had an excess of electrical wiring configurations suggestive of high current-flow compared with control children’s homes. The association was strongest among children who had lived their entire lives at the same address and appeared dose-related; it did not seem attributable to neighborhood, street congestion, social class, or family structure.

In sartorius muscle cells from frogs exposed chronically to pulsed 2.88 GHz microwaves (10 mW/cm2, 0.1 h daily, up to 100 days), the temperature dependence of measured passive and active electrical parameters (10–30 °C) was not altered compared with controls. The authors report no cumulative muscle cell bioeffects under these exposure conditions.

The article discusses increasing community exposure to microwave radiation and notes that East European countries report adverse effects at exposure levels lower than those permitted in Western countries. It emphasizes the need for epidemiologic studies in humans to detect potentially subtle effects and notes that exposure indices and dosimetry are becoming applicable to field studies.

At higher microwave dose rates (>10 mW/g), SMR decreased in some cases at 20°C and 24°C. At 35°C, high-level microwave dosing increased SMR over sham. A possible trend toward increased SMR during and after low-level (1.6 mW/g) exposure was noted at 24°C and 30°C.

Exposure to 10,000 MHz microwave radiation at 0.58 mW/cm2 for 30–120 min was associated with a 30–60% decrease in the bacteria’s ability to produce tumors on potato and turnip disks. The exposure did not affect bacterial viability or attachment to a tumor-binding site and did not induce thermal shock; the loss of virulence was reversible within 12 h.

Repeated exposures to 3100 MHz pulsed radiation were associated with degenerative ultrastructural changes in retinal neurons and reactive changes in glial cells detectable by electron microscopy. A single exposure combined with induced 70–100% blood-pressure increase did not enhance blood-retinal barrier permeability to tracers, and there was no evidence of blood-brain barrier leakage.

Recent publications are selectively reviewed on radio and microwave interactions with biological systems, emphasizing low-level effects at or below accepted safety standards. The reviewed information is used to examine the adequacy of existing emission and exposure standards for controlling environmental levels and safeguarding the general population from deleterious effects under typically encountered U.S. exposures.

Low-level microwave radiation (3–4 mW/cm2 at 2450 MHz) showed no effect on digestive transit after 4 hours, but accelerated digestive transit after 8 hours (p<.001), with acceleration still observed 24 hours later (p<.001). Rectal temperature measured 60–90 seconds after radiation did not differ from controls.

The paper hypothesizes that solid-state plasma could occur in organic (biological) semiconductors and discusses conditions/parameters for such plasma in biological solid structures. It proposes that microwave radiation may support or damp plasma oscillations, potentially stimulating or suppressing biological functions.

In rats, low-intensity pulsed microwave radiation (average power density 1 mW/cm^2) potentiated the response-rate-increasing effects of chlordiazepoxide. The abstract states the microwave exposure alone had no apparent behavioral effects, but it modified the drug’s behavioral effects.

In 2072 rats, thresholds of power density and irradiation duration were obtained that produced no more than 0.1% destruction. The ratio/speed of destruction versus regeneration depended on power density and followed an exponential relationship. Compared with previously reported mouse experiments, mice were described as more sensitive than rats in time to achieve equal destruction effects and in regeneration timing and speed ratios as a function of power density.

The authors developed miniature anechoic chambers enabling individual chronic microwave or sham exposure of animals under controlled environmental conditions. Field patterns were reported to correspond closely to those in large anechoic chambers; measurements indicated 169 microW/cm2 per watt of input power, yielding peak SAR levels of 0.37 W/kg in cadavers of exposed rats.
