Measurement of Radiofrequency Power Absorption in Monkeys, Monkey Phantoms, and Human Phantoms Exposed to 10-50 MHz Fields.
Abstract
The power absorbed by biological systems and thus the biological insult vary as a function of the frequency of the incident radiofrequency (RF) field. To define the effects of RF radiation on man, it is necessary to quantitate the absorbed power in man and experimental animals over a broad range of frequencies. Prolate spheroid phantoms representing man and monkey were used to determine the absorbed power by differential power measurement techniques, and these data were compared with theoretical results. Power absorption measurements were performed on live monkeys, and these results were compared with the results using phantoms to determine the adequacy of the prolate spheroid model. The results indicate the theory to be excellent for predicting power absorption in the phantom, but the more complex ellipsoid model will be required to predict power absorption in primates.
