Abstract:

An instrument for detecting natural body burdens of radionuclides has been constructed at USAMRNL. The counting system uses a NaIT1 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 301355 computer and punched paper tape. The detector was calibrated for measuring body potassium using six subjects with weightheight ratios varying from 0.368 Kgcm to 0.620 Kgcm. The calibration factor was found to be a linear function of weightheight 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.
