Stewart J. Allen et al. · 1975
Researchers calculated and measured radiofrequency power absorption from 10 to 50 MHz in prolate spheroid phantoms and live monkeys. Monkey orientation affected absorption, with monkeys on their sides absorbing more power than on their backs for cross and magnetic polarization.

Researchers cultured embryonic chick tibiae in vitro and exposed them to either a static or a pulsed electric field. Histological examination and macroscopic photographs showed no differences in growth patterns between test and control bones.

In mating combinations that included a treated male, females laid significantly fewer eggs than in combinations with a treated female, and egg production decreased with longer exposure times. Hatch percentages did not differ significantly across any mating combination. Progeny of RF-treated adults laid far fewer eggs (142.9 vs 296.9) but had similar hatch rates (71.0% vs 77.7%). Adults emerging from RF-treated larvae also laid fewer eggs (81.1-98.1 vs 154.4) with no significant difference in hatch percentages.

Watson et al. found that the growth rate of embryonic chick tibiae in vitro was enhanced by a pulsed electric field of 1,000 V cm but not by a static field. The authors suggest that the lack of enhancement in a static field is due to the ability of the cultures to sustain a field. They explain that during the 9-day growth period in a steady field there is no field within the bone, no charge movement, and thus no bioelectric command signal except at the instants when the field is switched on or off. They derive a relaxation time constant of about 10 seconds for the tissue, indicating that in a steady field there is no transducer mechanism available.

Researchers exposed individual CF1 mice to 2450 MHz microwave radiation in a waveguide with controlled temperature, humidity, and air flow. Female mice in estrus had a lower average lethal absorbed dose (10.65 cal/g) than those in diestrus (11.50 cal/g). Pregnant mice exposed on gestation day 8 showed teratogenic effects including exencephalies, hemorrhages, resorptions, stunting, and fetal death at absorbed doses of 3 to 8 cal/g, and the response was not all-or-none. As absorbed dose increased, the probability of at least one exencephaly per litter increased, but the relationship was not linear and varied widely among litters. A total of 1096 mice were exposed and monitored individually.

The review explains that microwave bioeffects data come from animal experiments, model studies, and epidemiological research on occupationally exposed persons. Animal experiments are divided into acute high dose and chronic low dose exposures, with high dose effects explained by non-uniform deep body heating. Chronic exposure effects, especially frequency and modulation dependent effects in the nervous and hematopoietic systems, cannot be explained by thermal considerations alone.

Approximately 70% of red cells were retained until the field was turned off, with no evidence of immediate cell destruction. Scanning electron microscopy revealed slight surface abnormalities on a small proportion of filtered cells.

Mice were exposed to 19 MHz radiofrequency radiation and then euthanized by microwave-heating brain inactivation. There were no significant differences in any neurotransmitters or metabolites when microwave controls were compared to either the E-field or H-field groups. Microwave controls had significantly higher brain content of 5-hydroxyindole acetic acid, serotonin, norepinephrine, and dopamine than conventional controls.
