NaI Scintillators
The SG 65 and SG 66 scintillators have been deve-
loped for safety related monitoring of activity according
to KTA 1502. In the scintillator crystal, ionizing radia-
tion generates light pulses, which are converted and
ampli ed into charge pulses by the photo multiplier.
The height of the pulse is proportional to the energy
of the gamma radiation. An adjustable pulse ampli er
offers calibration of the sensitivity and matching of the
output pulses to the impedance of the detector cable.

liquids
