Abstract

The embodiment of the invention provides a radioactive inert gas measurement device and method, equipment and a storage medium. According to the device, signal detection equipment detects a beta-gammacoincidence pulse electric signal obtained through the action of a sample and a detection crystal, and a beta detection crystal and a gamma detection crystal in a detector are arranged in a combinedmanner; the beta-gamma coincidence pulse electric signal is converted into a digital form from an analog form by signal acquisition and processing equipment; a computing device analyzes the amplitudeof the beta pulse signal in the beta-gamma coincidence pulse electric signal to obtain a first amplitude and the amplitude of the gamma pulse signal to obtain a second amplitude; and the activity concentration of the inert gas nuclide in the sample is calculated according to the pulse count of the digital beta-gamma coincidence pulse electric signal in the amplitude range formed by the first amplitude and the second amplitude. According to the scheme, the accuracy and reliability of measurement can be improved, radioactive inert gas nuclides can be distinguished, the concentration value of activity can be accurately and continuously measured, and the size, weight and cost of the detection device can be reduced.

Description

technical field [0001] The invention relates to the technical field of environmental radiation monitoring, in particular to a measuring device, method, equipment and storage medium for radioactive inert gas. Background technique [0002] During the operation of nuclear power plants, nuclear tests, isotope production, and nuclear fuel reprocessing, radioactive nuclides may be released and spread into the atmosphere, endangering environmental safety and personnel health. Among them, radioactive inert gas may be produced due to fuel cladding damage or activation of neutron absorption by materials in the core area. Its monitoring is of great significance for ensuring the operation safety of nuclear facilities and the health of environmental personnel. [0003] As the fission product of nuclear fuel, radioactive inert gas has stable chemical properties and large output, and is an important monitoring source item for environmental assessment of nuclear facilities. The source term...
