Spectrometer – Nuclide Identifier AT6101

AТ6101 and AT6101B Portable multifunction scintillation gamma spectrometers can be used in laboratories as well as for working in field conditions. Main spectrometer function is radionuclide identification (natural, medical, industrial) without connection to a PC.  Additional functionality: search and detection of radioactivity sources and dose rate measurement.
