In order to assess the reliability of Monte Carlo (MC)-based
numerical calibration of in vivo counting systems the EURADOS network supported a comparison of
MC simulation of well-defined experiments. This action also provided training for the use of
voxel phantoms. In vivo measurements of enriched uranium in a thoracic phantom have been carried
out and the needed information to simulate these measurements was distributed to 17 participants.
About half of the participants managed to simulate the measured counting efficiency without
support from the organisers. Following additional support all participants managed to simulate
the counting efficiencies within a typical agreement of +/- 5% with experiment. (C) 2012 Elsevier
