A prototype RAD HAZ suit was developed through the joint efforts of NSRDF and NAVAPLSCIENLAB to protect naval personnel required to operate in hazardous RF environments on ships and at shore installations. The suit's silverized nylon material withstood laundering, dry cleaning, weathering, abrasion, and open-sea environments without degradation of RF attenuation. The prototype suit provided better than 20 dB attenuation for high-power fields at BMEWS frequency with a power density of 200 mw/sq. cm, and field evaluation showed good performance with no meter deflection or visible arcing.

The technical objective was to determine the reflection and absorption characteristics of the human body when exposed to microwave radiation. Transmission characteristics of a sample in a waveguide were measured starting with X-band and the work was planned to extend to other frequencies, modes, and pulsed radiation.

Clostridium welchii type A toxin showed no change in toxicity when tested by human serum opacity and mouse lethality studies. Flocculation tests found no change in antitoxin combining capacity or antigenicity of diphtheria toxin. The authors questioned the efficacy of available assay procedures and called for more precise methods.

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.

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.

The document reviews published papers on radio frequency radiation effects on biological subjects. It gives separate coverage to the susceptibility of the head, eye, and testis to RF radiation. It also discusses ionizing radiation produced by RF generating equipment. The document draws no conclusions and makes no recommendations.

Electromagnetic radio-frequency fields and X-rays are considered harmful because they are invisible and not detected by sensory organs. Workers often underestimate the harmful effects of radiation. Currents above 50,000 cps do not pose electric shock danger, but burns from high-frequency heating installations are a risk. High voltages on electrodes present additional danger. The intensity of the electromagnetic field depends on the frequency of the generator and the distance from the radiation source to the operating location.

Tolerable levels of 10 mw/cm² average power density for personnel and 5,000 mw/cm² peak power density for aircraft refueling were recommended. Insufficient information was available for HERO tolerable levels, safety regulations, protective materials, and measuring equipment. Pearl chain formation, Hall effect, and gaseous breakdown were found unsuitable for broadband sensors, while radiation pressure, absorption, and Kerr effect showed promise.
