Description
Application
The MZHG-A Water Contamination Monitoring Systems can be used for continuous automated radiation monitoring of liquid discharges, process media, unbalanced water and waste water at nuclear power plants and other enterprises using gamma-emitting radionuclides in their processes, as well as for monitoring of drinking water at water intakes and for environmental monitoring.
Design
Depending on the version, radiometers can include one or two UDS-GC gamma detecting devices based on NaI(Tl) (Ø40×40) mm or NaI(Tl) (Ø76×305) mm crystals, installed in measuring chambers in flow-through versions (for MZHG-A01, MZHG-A02, MZHG-A04) or designed as submersible or mortised units (for MZHG-A03, MZHG-A05, MZHG-A06), and a spectrometric processing unit. Lead shielding blocks surrounding the measuring chamber from all sides reduce the influence of external background during measurements.
The spectrometric processing unit includes a panel computer with specialized software installed, as well as power supply and communication units for the radiometer components.
The MZHG-A Water Contamination Monitoring Systems were developed basing on the 20 years of successful operation of its prototype (RSKV-01 Radiometer-Spectrometer for Water Radiation Control) at water intakes of water utilities and at the enterprises using gamma-emitting radionuclides in their processes.
