  • Type:

    scintillation, gamma

  • Other characteristics:

    high-sensitivity, monitoring, real-time


With expanded nuclide library

Highly sensitive selective wide-range spectrometric scintillation gamma activity monitor is intended for measuring volumetric (specific) radionuclide activity in 131I, 134Cs, 137Cs, 40K samples with 1 litre Marinelli beaker and 0.5 and 0.1 litre flat-type containers.

Operating principle

Gamma activity monitor operating principle is based on the detection unit pulse-height distribution analysis.

Energy distribution parameters are processed in energy windows with the help of matrix method.

Matrix method allows measurement of volumetric (specific) activity for monitored radionuclides based on energy windows count rate.
Measurement results are displayed on Information processing unit screen in real-time.

Gamma radioactivity monitor has a PC-detecting unit connection option.

Application software replaces Information processing unit and is used for controlling radioactivity monitor modes, measurement data display, spectra processing, electronic history logging and recording of measurement results.
