1 DESCRIPTION AND OPERATION OF THE PRODUCT

1.1 Product functionality

Scintillation gamma-spectrometer «Progress-gamma» FVKM.412131.002-03 (hereinafter –

gamma-spectrometer) represents a part of a spectrometric complex «Progress» for measurement of

activity of alpha-, beta-, and gamma-emitting radionuclides and can be used independently.

Gamma-spectrometer is intended for measurement of activity of gamma-emitting radionuclides

in samples of the foodstuffs, samples of biological origin, water and soil samples, and other

environmental samples in the laboratory.

Gamma-spectrometer can be used for radiation monitoring at nuclear plants, at the enterprises

and facilities which produce or use sources of ionizing radiation.
