Uncertainty analysis of calibration factor of radon monitor
摘要
Abstract
The uncertainty of the calibration factor is an important parameter to evaluate the calibration results and is an important basis for the evaluation of the measurement results of radon monitor.In this paper,the uncertainty source of calibration radon monitor is analyzed by using radon chamber.The relative standard uncertainty of the calibration factor was measured.The results show that the main influencing factors of the uncertainty of the calibration factor include:the repeatability of the standard instrument and the measured instrument;standard instrument calibration factor and its annual stability;inhomogeneity of test area of radon chamber device.Finally,the relative standard uncertainties of the calibration factors at each measurement point are 4.1%,3.6%,and 3.3%,respectively.关键词
