 Gabi Star

Gabi is a modular radioactivity flow through detector for high energy beta, all gamma and positron emitters.
The microprocessor controlled system can be used either as standalone version via analog output or PC controlled trough Gina Star software.
Gabi controls several different scintillation probes with various types dimensions and shapes of scintillation crystals to optimize performance for all applications.



Scintillation probe for high beta, gamma and positron emitter

raytest scintillation detector for Gabi for the high beta emitters like 32P and gamma emitters like 123I, 125I, 131I, 99mTc , 137Cs ... use the NaI detection techniques.


raytest offers three scintillation detectors with various types, dimensions and shapes of scintillating crystals to optimize performance and applications.
