What's ahead for microwaves

Jeffrey Frey, Raymond Bowers · 1972

The article describes how inexpensive solid-state microwave sources will enable massive new applications in homes, vehicles, and commercial systems. It identifies spectrum congestion as a growing problem with current allocation methods becoming inadequate. The authors note the FCC can regulate power density based on physiological studies but has not yet issued such regulations. They list specific questions including potential health hazards from increased microwave exposure. The article recommends a complete spectrum usage database and new frequency assignment principles.

Deformity and Intra-Uterine death after short wave therapy

Dietzel F, Kern W, Steckenmesser R · 1972

Researchers exposed 749 pregnant rats to a single abdominal short-wave treatment during the first 16 days of pregnancy, raising rectal temperatures to about 40° within 10 minutes. Treatment on the first two days of pregnancy caused 65% embryo deaths compared to 25% in controls. Embryonic injuries occurred only when maternal rectal temperature reached at least 40° for 10 minutes; lower temperatures caused no injuries.

Heliobiology

Alexander Dubrov · 1972

Dubrov worked in heliobiology studying the effects of solar activity and natural magnetic and electric fields on living organisms. He found that cell membrane permeability is under direct control of the geomagnetic field. Chizhevsky showed that epidemics, diseases and death rates follow 11-year cycles similar to sunspot cycles.

A HIGH-SENSITIVITY, ULTRA-BROADBAND RADIATION PROBE

S. Hopfer · 1972

The probe is designed to cover 10 MHz to 20 GHz with full-scale sensitivities from 100 μW/cm² to 10 mW/cm². Calculations predict a flat characteristic from 10 MHz to 20 GHz and a sensitivity more than 23 dB above thermo-electric probes. Initial measurements on the prototype confirmed a flat characteristic through 18 GHz and a 400-fold sensitivity improvement.

Microwave health hazard: control of

Chief, Bureau of Medicine and Surgery · 1972

The instruction outlined potential health hazards from microwave equipment including radar and set maximum personnel exposure levels. It described that below 1 GHz energy penetrates deep tissues while above 3 GHz heating occurs near the body surface. The eyes and testicles were identified as the most vulnerable organs; the lens can develop cataracts from intense microwave radiation, and testicular effects are considered temporary. Exposure limits were set at 10 mW/cm² for exposures greater than 30 seconds and 300 mJ/cm² for intermittent exposures of 3 to 30 seconds. Medical surveillance required preplacement and periodic examinations, including a comprehensive ophthalmological examination with slit-lamp evaluation, and immediate examination after overexposure above 50 mW/cm².

Interaction Between a Linearly Polarized Electromagnetic Plane and a Double Spherical Shell

Daniel L. Dawes, Jerry W. Gaskill · 1972

Researchers modeled a double-shelled spherical acrylic plastic enclosure irradiated with 2450-MHz microwaves. They compared standing wave patterns for chambers made of Plexiglas, Teflon, and styrofoam. Plexiglas and Teflon chambers produced similar standing wave patterns with hot spots more than three times the incident field strength. Styrofoam showed a much smaller standing wave pattern with a hot spot less than 6 percent above the incident field. The authors concluded styrofoam would be a much better material for exposure cells if it meets mechanical requirements.

BIOLOGICAL EFFECTS OF NONIONIZING RADIATION

Saul W. Rosenthal · 1972

Rosenthal noted that U.S. and Soviet microwave safety standards differed by three orders of magnitude, indicating a serious lack of knowledge about biological effects. He also noted the Occupational Safety and Health Act of 1970, which gave the Labor Department responsibility for occupational standards covering nonionizing radiation. Rosenthal stated that no coordinated research program existed to establish a scientific basis for determining potential hazards of nonionizing radiation.
