| Digital hand held spectrometer and
dose rate meter with nuclide identification |
Infrared data transfer
Features
Identifinder allows to distinguish
man-made and natural isotopes. It combines high sensitivity with a
wide dose rate range. Identifinder performs gamma spectrometry and
nuclide identification.
Identifinder is a complete digital gamma spectroscopy and dose rate
system. It integrates multi-channel analyzer, amplifier, high voltage
power supply, and memory with an integral scintillation detector.
Identifinder is suited for remote applications, advanced warning systems,
hazardous environments and nuclear inventory monitoring. It can be
used with standard detector Ø 1? x 2? NaI(Tl), or the optional
available BGO or CdWo detector as well as CdZnTe.
A built-in 137Cs reference source (¼ 500 Bq/15 nCi) is used for
online stabilization and in-situ calibration without user interaction.
This special Identifinder feature allows operational temperatures between
–15°C and +55°C and large temperature gradients.
Connected to a computer via infrared
Connected to a desktop or notebook
PC, the unit provides qualitative and quantitative in-situ analysis
with optional gamTMCA-N software. Up to 70 spectra of 1024 channels
can be stored in the unit and directly transferred to any PC for
further and advanced analysis.
Standard winTMCA software is part of delivery.

The operator can select from 6 sub-libraries
(Nuclear, Industrial, Medical, Customs, CTBTO, and User). All
sub-libraries except CTBTO can be edited by adding or deleting
specific nuclides from the list.
Ten (10) reference spectra can be
measured by the user and added to the predefined library spectra.
Identification is done by a template matching correlation procedure.
