Price of nuclear radiation online monitoring system

Online monitoring system for gamma radiation in water

Online monitoring system for gamma radiation in waterFrom low backgroundγComposed of energy spectrum measurement device, spectrum analysis and nuclide analysis unit, data storage and communication unit, water sampling device, site and supporting facilities, etc. Can objectively reflect the water bodyγRadiation environment quality situation and changes，Provide monitoring data for radiation environment assessment, medical wastewater radioactive supervision, nuclear facility management, and nuclear and radiation safety emergency response.

The real-time online monitoring system for water radioactivity extracts water samples from the monitored watershed, analyzes and calculates the activity concentration of radioactive nuclides in the water and the total amount in the waterγRadioactive activity concentration. This instrument uses gamma spectroscopy analysis method to continuously monitor the activity concentration of various radioactive elements in water，And display, record, and analyze measurement results in real time on the industrial computer，Can achieve unmanned work site, etcinformation.

Application fields:

The real-time online monitoring system for water radioactivity can be widely used for monitoring radioactive waste liquid in hospitals, watersheds near nuclear power plants, and storage water tanks in food irradiation processing plants, among other places that require water radioactivity monitoring. In order to meet regulatory requirements in radioactive waste discharge operations, and to take timely, accurate, and effective measures to protect personnel safety.
