Treatment of Soft-tissue Injuries by Pulsed Electrical Energy

D. H. Wilson · 1972

Twenty matched pairs of patients with recent ankle sprains received either active pulsed high-frequency electrical energy or a placebo treatment for one hour daily over three days. Treated patients showed about twice the percentage improvement of placebo patients in each category, with pain improving 74.4 versus 32.4 and disability 86.9 versus 43.9. Statistical analysis found the active treatment significantly preferable for pain, disability, and total scores, with all matched-pair P values below 0.05.

Clinical Aspects of Nonionizing Radiation

Milton M. Zaret · 1972

The author reviewed clinical ocular injuries from nonionizing radiation, distinguishing between visible and invisible wavelengths. In workers exposed to high-intensity light sources, macular hyperpigmentation and depigmentation were each found ten times more often than in the general population. Retinal burns and melanomata were each observed in 1 percent of the examined workers.

Opacities may also result as a cumulative effect of repeated subthreshold exposures. Intraocular temperature increases during irradiation, related to power density, but a particular critical temperature for opacity induction cannot be identified.

Viability Studies on Ascospores and Vegetative Cells of Saccharomyces cerevisiae Exposed to Microwaves at 2450 MHz

P. C. B. Roberts · 1972

Researchers exposed Saccharomyces cerevisiae vegetative cells and ascospores to 2450 MHz microwaves using a hexane-cooled apparatus designed to separate thermal from non-thermal effects. At 40 watts without coolant flow, total loss of viability occurred after 30 seconds for vegetative cells and 40 seconds for spores, while suspension temperatures remained below 33°C.

FIELD TESTING OF MICROWAVE OVENS

Office of Training, Division of Electronic Products · 1972

Interlock testing requires at least two operable safety interlocks and the oven should turn off before leakage exceeds 5 mW/cm² during slow door opening. Closed-door leakage measurements use a standard water load of 275 ml in a 600 ml beaker and the probe is moved along the door crack at no faster than one inch per second. Ovens manufactured after October 6, 1971 must bear a DHEW certification label showing compliance with 42 CFR Part 78.

Microwave Radiation: Biophysical Considerations and Standards Criteria

Herman P. Schwan · 1972

Nonthermal effects are classified as strong (above 10 mW/cm²) or weak (below thermal levels), and the review finds no evidence for weak nonthermal effects. The 10 mW/cm² exposure standard is based on thermal considerations and applies only to microwave frequencies where the human absorption cross-section is near unity; at lower frequencies the guide numbers can be relaxed by orders of magnitude.

THE EFFECT OF MICROWAVE RADIATION ON EVOKED TACTILE AND AUDITORY CNS RESPONSE IN CATS

Arthur W. Guy, James C. Lin, Fredric A. Harris · 1972

The study exposed cat heads to 915 MHz microwave radiation and measured evoked tactile and auditory CNS responses. Changes in latency and/or amplitude occurred at a mean threshold of about 5 mW/cm2. Temperature rises were always associated with the changes. Variations in results were noted with different electrode compositions, suggesting possible artifacts.

Insect-Control Possibilities of Electromagnetic Energy

S. O. Nelson · 1972

Gamma radiation at 16 kilorads can sterilize most stored-grain insects, while 20 to 30 kilorads may be needed for all species, and the FDA has approved its use for wheat and wheat flour. Infrared heating of grain to 65°–70°C controls all developmental stages of stored-grain insects, but the treatment cost has prevented practical use.
