Development and Application of a Whole-Body Radiation System,
Abstract
An instrument for detecting natural body burdens of radionuclides has been constructed at USAMRNL. The counting system uses a NaI(T1) scintillation crystal and a lead shadow-shield. The subject passes beneath the detector on a padded sled at a speed proportional to the live time of the multichannel analyzer. Data is analyzed using the RCA 301/355 computer and punched paper tape. The detector was calibrated for measuring body potassium using six subjects with weight/height ratios varying from 0.368 Kg/cm to 0.620 Kg/cm. The calibration factor was found to be a linear function of weight/height for the range of body sizes considered. The counter has been used for measuring potassium, for body composition studies, and for tracer isotope retention measurements.
