title: Experimentally validated Monte Carlo simulation of an XtRa-NaI(Tl) Compton Suppression System response.
abstract: In this work the response of an XtRa-NaI(Tl) Compton Suppression System is simulated using the Monte Carlo code PENELOPE. The main program PENMAIN is properly modified in order to couple two energy deposition detectors and simulate the coincidence gating. The modified main program takes into account both the active shielding and the True Coincidence phenomenon. The program is evaluated by comparing simulation results with experimental data for both non-cascade and cascade emitters and concluding that no statistically significant biases are observed.
