Leakage in the Proximity of Microwave Diathermy Applicators Used on Humans or Phantom Models

Howard I. Bassen et al. · 1978

This 1978 government report investigated electromagnetic radiation leakage from microwave diathermy machines, which use focused microwave energy for deep tissue heating in medical treatments. The study measured how much microwave radiation escaped from these therapeutic devices when used on human patients and laboratory test models. This research was part of early efforts to understand occupational and patient exposure risks from medical microwave equipment.

An Analysis Of Radiofrequency And Microwave Absorption Data With Consideration Of Thermal Safety Standards

Richard A. Tell · 1978

This 1978 EPA technical report analyzed how radiofrequency and microwave radiation is absorbed by biological tissue, specifically examining thermal safety standards used to protect people from heating effects. The study represents early government efforts to establish exposure limits based on the assumption that heating is the primary health concern from RF radiation.

MEASUREMENT OF POTENTIALLY HAZARDOUS ELECTROMAGNETIC FIELDS--RF AND MICROWAVE

Unknown authors · 1978

Instruments should read average power density, mean squared electric field strength, mean squared magnetic field strength, or energy density. Calibration methods include free-space standard field, guided wave methods, and standard probe method.

RF Cell Culture Irradiation System with Controlled Temperature and Field Strength

Arthur W. Guy · 1977

The system was designed for the National Institute for Occupational Safety and Health to determine human RF exposure thresholds in the frequency range D.C. to 100 MHz. The final design uses concentric stainless steel rings with a teflon bottom that forms a liquid-tight seal compressed by brass retainer clamps.

RF Cell Culture Irradiation System with Controlled Temperature and Field Strength

Arthur W. Guy · 1977

This 1977 NIOSH technical report describes the development of a radiofrequency (RF) cell culture irradiation system capable of controlling both temperature and electromagnetic field strength. The research focused on creating standardized laboratory equipment for studying how RF radiation affects living cells in controlled conditions. This represents early foundational work for understanding cellular responses to electromagnetic field exposure.

RF Cell Culture Irradiation System with Controlled Temperature and Field Strength

Arthur W. Guy · 1977

NIOSH researchers developed a specialized laboratory system in 1977 for exposing cell cultures to radiofrequency (RF) radiation while precisely controlling temperature and electromagnetic field strength. This technical report describes equipment designed to study how RF energy affects living cells under controlled laboratory conditions. The system represented early efforts to standardize RF exposure research and eliminate confounding variables like heat effects.

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.
