Measurement of RF Power-Absorption in Biological Specimens (10 to 100 MHz)

Frank M. Greene · 1977

The exact measurement point on the feed line is not critical, and measurements can be made at full operating power without interrupting exposure tests. In an example with 100 watts forward power and 11.1 watts reflected power, the specimen absorbed 44.4 watts, which is half the load power. The absorbed power can never exceed half the forward power, reaching this maximum when reflected power is 25 percent of forward power.

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.

RF Radiation Absorption Patterns: Human and Animal Modeling Data

Arthur W. Guy, Michael D. Webb, John A. McDougall · 1977

This 1977 government study examined how radiofrequency radiation is absorbed by human and animal bodies, creating mathematical models to predict absorption patterns. The research established foundational methods for understanding how RF energy penetrates and distributes throughout biological tissues. This work became crucial for developing safety standards and exposure limits still used today.

ELECTROMAGNETIC LEAKAGE MONITOR "MINI-SURVEYOR" WITH 30 dB DYNAMIC RANGE

Unknown authors · 1977

This 1977 technical report describes a portable device designed to detect electromagnetic leakage from microwave sources, specifically targeting 2450 MHz frequencies with 30 decibel measurement range. The device was developed as a mini-surveyor tool for monitoring microwave radiation emissions in various environments. While no specific health findings are detailed, this represents early recognition of the need to measure and monitor microwave radiation exposure levels.
