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.

Two hundred male mice were exposed daily for 59 weeks to 0.100 w/cm’ for 4.5 minutes, producing an average body temperature rise of 3.3°C. A control group of 100 mice was sham-irradiated in a mock-up chamber at room temperature. Longevity did not differ between groups, with mortality slightly higher in controls. Body weight, body temperature response, and blood picture showed no evident changes. Testicular degeneration (tubule atrophy) was found in 40 per cent of dead irradiated mice versus 8 per cent of controls, and white cell neoplasms (leucosis) in 35 per cent versus 10 per cent.

The study used the luminescent bacterium Photobacterium fischeri exposed to continuous-wave microwaves at 12.8 Mc intervals between 2608.7 and 3082.3 Mc. Initial measurements suggested reduced luminescence in exposed samples, but the difference was traced to Pseudomonas contamination from distilled water used to rinse the apparatus. After sterilizing the system and using sterile water, no significant difference in luminescence between exposed and control suspensions was observed 20 to 24 hours post-exposure.
