Scintillator
The DuoSeries detectors differ in their external dimensions and the scintillators
used. Point detectors are equipped either with a 50/50 (diameter x length) NaI scin-
tillator or a 50/60 polymer scintillator. Polymer scintillators are used in the rod de-
tectors (models are available with the sensitive lengths of 500 mm, 1000 mm, 1500
mm and 2000 mm). The size of the scintillator determines the size of the sensitive
area (the area that is used for the measurement). Marking grooves (Fig. 3) on the
detector housing mark size and position of the sensitive area.
