Stabilization In the non-Ultra models a built-in 137Cs reference source (<15 nCi/500 Bq) is used for online stabilization and in-situ calibration without user interaction. With either stabilization method this special identiFINDER feature allows operation over temperatures between -4 and 122 °F (-20 to
55 °C )

Software The identiFINDER provides for easy storage of up to 100 spectra and rapid transfer to a PC for reach-back and/or qualitative in-situ analysis with the software supplied

USER SELECTABLE NUCLIDE LIBRARY
There are 74 reference spectra of radionuclides stored in 6 libraries (Nuclear, Industrial, Medical, Customs, OSI, and Security). All sub-libraries except OSI 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
