Two case histories are described involving exposure to thermal/infrared radiation from an electric oven and range. In one patient, earlier exposure to medical diathermy appeared to initiate delayed capsular cataracts, with accelerated cataractogenesis after recent repeated intense infrared exposure. In the other patient, exposed solely to infrared radiation, a chorioretinal lesion consistent with repeated thermal radiation was observed and later capsular opacification became evident.

Exposure to weak sinusoidal electric fields (1, 6, 16, 32, or 75 Hz; 5, 10, 56, or 100 V/m in air) was associated with a general trend toward reduced 45Ca2+ efflux compared with unexposed matched controls. Maximum decreases were reported at 6 and 16 Hz (12–15%), with estimated thresholds around 10 V/m for chick tissue and 56 V/m for cat tissue; other exposures showed similar but nonsignificant trends.

In rabbit lenses exposed to cataractogenic microwave radiation at 2.45 GHz, epithelial DNA synthesis/mitotic activity showed two patterns depending on vesicle strings. Lenses without vesicle strings had an initial pronounced suppression of mitotic activity with gradual return to normal, while lenses with vesicle strings showed a marked rise in DNA synthesis on days 4–5 post-irradiation.

In 114 mice irradiated to death with 2450 MHz microwaves at 7.5 W forward power, time to death increased with age for both sexes. Mean absorbed dose at death (J/g) showed no significant differences related to age or weight within the same sex, but differences between sexes were reported as significant, particularly among aged ex-breeders; males showed a slight increase in radio-tolerance with age/weight compared with females showing a decline.

Microwave exposure (continuous wave and pulsed, 2.45 GHz; 5, 10, 25 mW/cm2) produced blood chemistry changes described as dose-dependent and consistent with non-specific thermal stress. Thermoregulation appeared sufficient at 5 and 10 mW/cm2 but could be overridden by a 2 h exposure at 25 mW/cm2; mild, repairable nephrosis was observed at 25 mW/cm2. In additional analeptic testing (5–50 mW/cm2), sleeping times decreased significantly and were reported as apparently proportional to power density below 15 mW/cm2.

In mice exposed to microwave radiation, the average absorbed dose to death increased as the rate of absorption decreased, indicating that absorbed dose alone was not sufficient for dosimetry. The authors attribute this to tissue heating and reduced ability to maintain homeostasis at higher heating rates, and conclude that both absorbed dose rate and exposure duration should be determined in microwave bioeffects experiments.

Atherosclerosis · 1976 · PubMed

In 16 rabbits, microwave exposure (2.45 GHz; 20–30 mW/cm2; 4 h/day, 5 days/week for 8–10 weeks) produced no differences versus matched controls in serum cholesterol, aortic wall cholesterol, or percent intimal surface with atherosclerotic lesions. Continuous RF irradiation (1 MHz; 30 V/cm; 8–11 weeks) also did not change these indices of atherogenesis.

The study investigated weak extremely low-frequency (ELF) electric fields (noted as similar to those associated with Project Seafarer) in mice and reported that electric field exposure acted as a stressor, with effects described on the central nervous and endocrine systems.

Across three successive generations continuously exposed to 60 Hz electric fields, mice exposed to vertical fields had decreased body weights at 35 days postpartum and increased mortality rates for all three generations. Mice exposed to horizontal fields had decreased body weights for two successive generations.
