The results of the intercomparison were reported in the paper "Monte Carlo modelling for the in vivo lung monitoring of enriched uranium: Results of an international comparison" The Lawrence Livermore National Laboratory (LLNL) lung phantom was simulated with and without a plastic over-layer and different activities of enriched uranium in both lungs. Four detector positions were used, as shown in Figure 1. VMC in-vivo was participant "I".
