This user manual FVKM.412131.002-03RE contains information on design, principle of
operation, characteristics of the scintillation gamma-spectrometer «Progress-gamma» and instructions
essential for correct and safe use of this product (intended use, maintenance, servicing, storage and
transportation), as well as information regarding the utilization of the product.
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.
