Geiger Müller detectors for gamma-ray tomography

Recent developments within Geiger Müller tube technology (GMT) make these detectors potential candidates for application in gamma-ray tomography (GRT) systems. GMTs are not energy sensitive, but are still applicable for pulse counting in GRT. GMTs have the advantage of being very rugged and requiring simple read-out electronics only.

They are also available at relatively low cost. Their drawbacks are limitations in gamma-ray stopping efficiency and count-rate capability. This paper presents methods whereby these properties can be improved significantly.
