Monte Carlo photons simulation from alpha-emitter radionuclides

Résumé

We present a Monte Carlo virtual source model for generating photons emitted during the decay chain of alpha-emitter radionuclides. The model, integrated into GATE 10, utilizes Geant4 databases to extract photon emission lines from decaying daughters. Employing Bateman equations for decay chain abundances and activities within a specified time range, it generates photons' energy and temporal distribution. By avoiding the need to simulate the entire decay chain, it reduces the computation time compared to reference ion source. The source model can be applied to any alpha-emitter radionuclide in the Geant4 database. It facilitates the investigation of (SPECT) imaging photon emission from alpha-emitters.
