OPERATION
The scintillation detecting device detects gamma radiation in the monitored fluid (water) and transfers the results in the form of spectra
to the PVC-03 control panel. Based on these data, the PVC-03 control panel calculates total gamma activity of the monitored water. If
the total gamma activity exceeds the preset threshold, sound and visual alarm is triggered. Measurements are performed in the continuous
automated mode. If the radiometer operates as part of a radiation monitoting system, spectra and processing results are transferred to
the upper-level computer for their detailed processing, including identification and calculation of activity of radionuclides, recording in the
data base and report generation.
The radiometer-spectrometer for water radiation control RSKV-01 (measurement chambler and local control panel PVC-03) is installed directly
at drawoffs. The operator's workstation is installed at the central control point.
CERTIFICATES
The radiometer-spectrometer for water radiation control RSKV-01 is enrolled in the State Register of Measuring Devices under № 22385-02
