Optimizing the Positioning of Detectors for Improved Counting Efficiencies Using Monte Carlo Simulations

Health Phys. 2024 May 1;126(5):309-314. doi: 10.1097/HP.0000000000001794.ABSTRACTThe Human Monitoring Laboratory (HML) at Health Canada updated its whole-body counter with four new electrically cooled HPGe detectors. To optimize the counting efficiency of the new system, Monte Carlo simulation was used to model the whole-body counter using a reference BOMAB male phantom. The resulting modeled counting efficiencies showed that the best position to install the four new detectors could be obtained without performing laborious real measurements, thereby reducing the cost of preparing the BOMAB phantoms and reconfiguring the detector arrays in multiple geometries, saving time and energy.PMID:38526249 | DOI:10.1097/HP.0000000000001794
