Abstract

The invention discloses a calibration method and system for a radioactive inert gas monitor, and the method comprises the steps: 1, carrying out the value determining for radioactive inert gas through a value determining system; 2, calculating a calibration factor of the detected radioactive inert gas monitor in the maximum range; 3, carrying out the first dilution for a cavity through a preset space in a volume determining device, and calculating the activity concentration of the radioactive inert gas after the first dilution; 4, carrying out the dilution for many times, and respectively calculating the activity concentration of the radioactive inert gas after dilution at each time; 5, calculating the calibration factor of a calibrated instrument in different ranges based on the calculated activity concentration of the diluted radioactive inert gas, achieving the calibration of the radioactive inert gas monitor, and guaranteeing the accuracy of the monitoring result of the radioactive inert gas monitor.

Description

technical field [0001] The invention relates to the field of measurement of ionizing radiation applied in nuclear technology, in particular to a method and system for calibrating a radioactive noble gas monitor. Background technique [0002] Radioactive inert gases are released during the operation of nuclear facilities such as military nuclear power plants, reactors, and nuclear power plants. The discharge of these inert gases is an important parameter for safe operation monitoring and can accurately reflect the operating status of nuclear facilities. At the same time, the discharge of radioactive inert gases into the air will cause environmental pollution and bring radiation hazards to personnel, especially in some special places where the space is small, if the generated radioactive inert gases cannot be effectively monitored and processed, it will cause great harm to personnel . Therefore, a large number of inert gas monitors are installed in these places for the measur...
