DEVELOPMENT OF OCCUPATIONAL EXPOSURE RECOMMENDATIONS: OBSERVATIONS ON THE USES OF RF/MICROWAVE ENERGY

National Institute for Occupational Safety and Health et al. · 1978

NIOSH mailed more than 300 contact letters in July 1978 to manufacturers, users, trade associations, professional societies, and labor unions. The letters requested information on bioeffects studies, engineering controls, medical monitoring, protective devices, measurement techniques, work practices, recordkeeping, and warning devices. The Summary Plant Observation Report prepared in March 1979 was incorporated into the draft criteria document chapters on environmental data and engineering controls and on work practices.

BIOTELEMETRY ANTENNAS IN BIOMECHANICS: THE PROBLEM OF SMALL BODY-MOUNTED ANTENNAS

NEUKOMM Peter A. · 1977

Maximum transmission loss increased from 20 to 30 dB as frequency rose from 200 to 1000 MHz at a 35 mm distance, and from 17 to 24 dB at a 77 mm distance over the same frequency range. The study concluded that ideal telemetry frequencies lie within 75-150 MHz, where losses stay below 18 dB at 35 mm and below 14 dB at 77 mm antenna-trunk distance. The flat helical dipole was recommended as the best antenna for biomechanics telemetry because varying body distance does not detune it out of its bandwidth.

NONIONIZING RADIATION PROTECTION SPECIAL STUDY NO. 42-0312-77 EVALUATION OF THE POTENTIAL RETINAL HAZARDS FROM OPTICAL RADIATION GENERATED BY ELECTRIC WELDING AND CUTTING ARCS

Wesley J. Marshall et al. · 1977

The US Army Environmental Hygiene Agency conducted a special study of the potential retinal hazards from direct viewing of various welding processes. The study evaluated gas tungsten arc welding, gas metal arc welding, flux cored arc welding, plasma arc cutting, plasma arc welding, and shielded metal arc welding. Spectral distribution was measured from 400 nm to 1000-1100 nm for each process.

Ocular Medical Surveillance on Microwave and Laser Workers

James A. Hathaway et al. · 1977

Researchers evaluated over 800 ocular examinations of microwave and laser workers using multiple regression analysis. No lenticular or retinal defects were attributed to microwave or laser radiation. Minute lenticular defects increased with age. Large differences in defect recording across installations were attributed to subjective evaluation by different examiners. The authors concluded that periodic medical surveillance as conducted was nonproductive and recommended limiting it to preassignment, postaccident, and termination examinations.

A SYSTEM FOR DETERMINING THE RADIOFREQUENCY ABSORPTION COEFFICIENT OF THE HUMAN BODY IN THE HIGH FREQUENCY BAND

Douglas A. Hill et al. · 1977

Researchers built a rectangular coaxial TEM cell to measure radiofrequency absorption in the human body from 10 to 26 MHz radiation. They made 17 preliminary measurements on three volunteers at 23.25 MHz, finding absorption results reproducible for each subject but differing between subjects. With 400 W incident power producing 1 mW/cm² power density, subjects absorbed 0 to 2 W, with higher absorption in EKH orientation than KEH orientation, and EKH absorption exceeded ellipsoid model predictions.

REVIEW OF OCCUPATIONAL SAFETY AND HEALTH ASPECTS OF ELECTROMAGNETIC PULSE EXPOSURE

A. Bruner · 1977

The report describes the typical occupational exposure to EMP at simulator facilities and summarizes medical surveillance observations. Data from informal observations and comprehensive annual physical examinations of approximately 600 workers exposed to various EMPs over a number of years disclosed no adverse health effects attributable to EMP exposure. A rodent study with continuous exposure to 447,000 V/m at 5 pulses per second for 38 weeks found no injurious effects. Bell Laboratories reported no noticeable effects in over ten persons exposed to pulses up to 100 kV/m. The Navy and other companies also reported no EMP health effects to OSHA in 1974.

Microwave therapy and muscle blood flow in man

D. R. McNiven, D. J. Wyper · 1976

Microwave therapy produced a highly significant increase in muscle blood flow in all subjects, raising the mean from 2.9 ml/100g/min at rest to 11.4 ml/100g/min at the end of application. Short wave diathermy, infra red irradiation, pulsed electromagnetic therapy, ice and massage produced no significant effect on muscle blood flow. No significant correlation was found between athletic fitness and blood flow or between resting blood flow and the time delay before the increase, which varied from 5 to 12 minutes.
