“…Une autre approche étu-diée au LNE-LNHB repose sur l'utilisation du code de simulation rayonnement-matière Geant4 [25]. Ce modèle stochastique permet de simuler le transport des photons Cherenkov à partir de leur création dans une solution aqueuse jusqu'à la production de photoélectrons au niveau des PM ; il nécessite une description complète de la géométrie de la chambre optique et des propriétés optiques associées [26]. Les deux modèles ont été utilisés pour la mesure d'activité de la solution diluée de microsphères dissoutes.…”

“…Energies lower than the Cerenkov threshold in the aqueous solution (~ 260 keV), are not detected. This paper presents an application of the new TDCRGeant4 model for the standardization of 11 C. The model was validated at first with the measurements of 90 Y (betaminus emitter with maximum energy of 2.3 MeV) using the Cerenkov radiation [4]. As Cerenkov emission is anisotropic and results from an electromagnetic process (no ionization quenching), these results provides a validation of the Geant4 model, without the need to simulate the physical chemistry processes causing liquid scintillation.…”
