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

amplifi 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 amplifi er

offers calibration of the sensitivity and matching of the

output pulses to the impedance of the detector cable.

APPLICATIONS

• Monitoring for gamma activity from in air and

liquids
