Metrological Parameters of the Unified Calibration Whole-Body Phantom with Gamma-Emitting Radionuclides

Abstract

The unified phantom UP-02T models children aged 2, 6 and 14 years, and adults with a body mass of 70, 90 and 110 kg with incorporated radionuclides. It is intended for calibration of whole-body counters with the investigated person in the standing and lying positions as well as sitting straight or stooping down. The phantom consists of a set of polyethylene rectangular blocks with masses 0.88 and 0.40 kg. A set of solid rod radionuclide sources, 6 mm in diameter, are inserted inside the blocks. Two sources are inserted in each block. The blocks are connected by means of fixing arms. The principal advantage of the solid phantom as compared to the phantoms that contain radioactive solutions is the safety of operation and the possibility of replacement of the radionuclide sources if it is necessary. The unified phantom was verified against the BOMAB calibration phantom and compared to the REMCAL type phantom.
