RF RADIATION HAZARDS TO SPACE STATION PERSONNEL

R. A. Inman · 1970

The purpose of this document is to examine the possible levels of RF radiation to which personnel on the space station and similar spacecraft might be exposed. The memo noted that formation of cataracts in the eyes of both experimental animals and man has been demonstrated after exposure for a few minutes. The memo concluded that personnel working in the field of these antennas should be protected from overexposure to this radiation.

Understanding Microwave Absorbing Materials and Anechoic Chambers-Part 2

Steven Galagan · 1970

Chamber length is determined by the antenna size and the highest test frequency. Chamber width must keep the angle of incidence at or below 60 degrees to maintain absorber performance. Tapered chambers can achieve better performance at lower frequencies and lower cost than rectangular chambers.

Mills LF · 1970

Researchers identified three populations treated with microwave diathermy at 2450 MHz for study. A second group comprises older patients with fair to poor health receiving weekly treatments for up to two years for temporomandibular joint conditions.

LABORATORY TESTING AND EVALUATION OF MICROWAVE OVENS

Stephen W. Smith et al. · 1970

Twelve ovens were on the U.S. market and two were prototypes, tested from August 1968 to April 1970. Leakage was measured at two inches from the oven surface using a Narda 8100 survey meter. Power density was also recorded at 30 centimeters with the door fully open and interlocks defeated. The data were not collected according to the proposed standard procedures, so comparison with that standard was not justified.

The document reviews scientific information on radiofrequency and microwave radiation and recommends a standard for controlling workplace hazards. The recommended limits apply to frequencies from 300 kHz to 300 GHz and are averaged over any 6-minute period during a workshift of up to 10 hours.

Quantifying Hazardous Electromagnetic Fields: Practical Considerations

Ronald R. Bowman · 1970

Power density is only useful for simple, uniform plane-wave fields and is unsuitable for complicated fields with reactive components or multipath interference. The total energy density of the field is the best parameter for quantifying hazardous fields, though electric energy density alone is often adequate. The field parameter approach is considered the most practical for general survey measurements.

ON THE POSSIBILITY OF NONTHERMAL BIOLOGICAL EFFECTS OF PULSED ELECTROMAGNETIC RADIATION

LAWRENCE D. SHER, EDWARD KRESCH, HERMAN P. SCHWAN · 1970

The study examined two mechanisms for alternating electrical fields interacting with biological tissue: heat development and field-induced force effects. For continuous wave fields in physiologic media, heating above 1°C always occurs before any field-induced force effect can appear. Using pearl-chain formation as a model, the researchers demonstrated that pulsed fields offer no greater likelihood than CW fields of equal RMS strength for producing pearl-chain formation.

APPLICATION OF MICROWAVE FREQUENCY MEASUREMENTS TO IDENTIFY PATHOLOGICAL COMPOUNDS IN BIOLOGICAL SPECIMENS

K. Bakin, E. E. Stickley · 1970

Dielectric relaxation times of dipole liquids are directly proportional to molecular radius and viscosity and inversely proportional to temperature. The Debye model, modified by a form factor for non-spherical molecules, can characterize molecular size and form from dielectric properties. Exploratory trials tested whether the method could detect shape or configuration variations in compounds from pathological situations. The method's sensitivity appeared to support its applicability, with further refinements in development.
