Calibration of a Large Hyperpure Germanium Array for in-Vivo Detection of the Actinides with a Tissue-Equivalent Torso Phantom

摘要

For calibration of the array for internally deposited exp 238 Pu, exp 239 Pu, and exp 241 Am, a tissue-equivalent anthropomorphic phantom, was used for efficiency determinations at the ORNL facility. This phantom consists of a tissue-equivalent torso into which is imbedded an adult male skeleton, interchangeable organs containing a homogeneous distribution of various radionuclides, and two sets of chest overlay plates for simulation of progressively thicker tissue over the chest, as well as differing thoracic fat contents.
