Realistic Monkey Models Made from Surgical Gloves for Radio-Frequency (RF) and Microwave Dosimetric Measurements

摘要

Common surgical gloves and a water-based, muscle-equivalent material were used to produce realistic models of rhesus (Macaca mulatta) and squirrel (Saimiri sciureus) monkeys for use in microwave and radio-frequency (RF) dosimetry. These models represent an improvement over previously used primate models that were typically encased in bulkly foamed plastic molds. The so-called rubber-glove monkey models did not require a mold for support, and therefore the models could be placed in the same restraint devices as used by live animals during various microwave and RF irradiation experiments. The rubber-glove models, moreover, provide the facility of easily changing the relative positions of the limbs, in contrast to the fixed posture of foam-encased primate models. Dosimetric results were obtained in a variety of configurations using the rubber-glove model. Specific absorption rate (SAR) is given for the plane-wave irradiation of the rubber-glove models at 225 MHz, 1.29 GHz, and 5.6-5.8 GHz. Additional SAR data is given for a rhesus monkey model inside a 275-MHz circular waveguide irradiation system.
