The researchers used continuous-wave microwave radiation at 5.5 kmc/sec to determine the threshold power levels that produce lens changes in rabbits after a single exposure. The results obtained are summarized in Fig. IV-5. Lens injury appeared by the fourth day as a small localized opacity at the anterior lens surface or a more extensive cataractous change in the anterior portion. The opacities either regressed, grew then regressed, progressed to a complete cataract, or occasionally resolved completely.

The RAD HAZ program was divided into Bio-Effects, HERO, and SPARKS subprograms to study hazards to personnel, ordnance, and flammable materials. Midwest Research Institute has worked on the program since May 1959 to gather data for radiation hazard standards. A tentative exposure limit of 10 mw/cm² for whole-body human irradiation was accepted by the Armed Forces but was not a universal standard. Animal research over four years showed that high RF fields can cause cataracts, burns, headaches, and fever, though no human fatalities were known.

Four sizes of polystyrene latex, starch grains, and gelatin-coated polystyrene showed a voltage-dependent, frequency-specific loss of negative surface charge when exposed to radio-frequency fields. Each particle size had a specific frequency at which maximum reduction in electrophoretic mobility occurred, for example 1.305 y-diam PSL at 13 000 Mc/sec and starch grains at 7.50 Mc/sec. The lost charge recovered linearly over hours, with larger particles taking longer, but a one-minute exposure to a different frequency restored the original charge. At high particle concentrations no mobility change occurred, yet diluting an already-exposed concentrated suspension caused its mobility to drop to the level it would have had if exposed while dilute.

The study found that 3 cm microwave radiation in short high intensity pulses is more stimulating than non-penetrating infrared radiation. Researchers deduced that 3 cm microwave radar antennae should provide ample warning of exposure because the radiation stimulates strong sensations of warmth and heat. Exposing large body areas to high intensity thermal radiation was very alarming to naive individuals and could cause immediate disruption of work even when not painful.

Researchers measured alternating electric fields at a VLF transmitter site operating at 14.7 kc with 1100 kw radiated power. At the tower top center the field was 30,000 volts per meter and tingling occurred on bare metal and sometimes on painted metal. At the ladder top the field reached 989,000 volts per meter, producing strong shocks comparable to a 115 volts ac line and causing reflex withdrawal without muscle freezing.

Researchers tested whether radio-frequency energy alters the pharmacodynamic properties of Salmonella typhosa endotoxin by irradiating it at 10.40 Mc/sec and 13.34 Mc/sec and administering it to dogs. Nonirradiated endotoxin produced a characteristic diphasic pressor response with an immediate transient mild rise followed by a more intense and prolonged rise that returned toward the pre-injection level. Endotoxin irradiated at 10.40 Mc/sec enhanced the first pressor response and caused the second response to remain permanently sustained without returning toward baseline. Endotoxin irradiated at 13.34 Mc/sec intensified the first pressor response but did not alter the second response pattern.
