Products  >>  Spectrometry  >>  Gamma spectrometer AirSPEC

Spectrometer AirSPEC is intended for automated radiation environment monitoring, measurements of ambient air volumetric activity  and gamma-radiation ambient dose equivalent rate  nearby the filter, comprising natural and artificial gamma-radiating radionuclides detected in aerosoles of ambient air surface layer.

The spectrometer is applied in the systems of air sampling as well as radiation monitoring stations.

The spectrometer AirSPEC is a all-in-one unit which contains processing unit within the cover. Smart detection unit of the spectrometer contains scintillation detector (several type), photomultiplier tube (PMT), spectrometric tract stabilization system (LED or Am-241), HV-generator, amplifier, multichannel pulses analyzer (MCA) and temperature sensors. The spectrometer is placed into thermostabilized and damp proof housing.

Though the present measurement system is autonomous and automated, the operator thanks to the possible remote access to the spectrometer may perform the analysis of the measured spectra with application of modern and comprehensive software.
