Abstract
Inrichting die voor het detekteren van de stralingsquanten voorzien is van een scintillator (10), die gekoppeld is met een fotodetektor (20) voor het omzetten van de scintillaties. Deze inrichting omvat een op een omzettingscircuit (40) aangesloten digitale circuit, waarmee de inrichting van niet gesuperponeerde stralingsquanten de energie van elk stralingsquant bepaalt, en in het geval dat de stralingsquanten gesuperponeerde stroompulsen opwekken, energieinhoud van de stralingsquanten bepaalt door extrapolaties en korrekties met behulp van een geheugen (170) en/of (180).
