Abstract:
Based on the results of the basic data construction radiation (Metadata Set of Radiation Stations), the metrological performance parameters of the national operational total radiation meters from 1990 to 2012 are collected and analyzed. The stability of total radiation meters at national radiation observation stations is analyzed statistically, and the results show that the stability of 561% domestic total radiation meters used in the operational observation of China meets the high quality requirements of WMO; 634% meets the good quality requirements; and 768% meets the medium quality requirements; 91% meets the requirements of oneyear stability within 5% of the Total Radiation Meter Metrological Calibration Regulation of China; 948% meets the requirements of 2year stability within 8%. The stability of China’s domestic total radiation meters basically meets the requirements, and its longterm stability is good. At the same time, a new radiation metadata set of radiation observation stations, which has marked the obvious errors and questions and includes the statistical analysis results of the total radiation sensitivity, is formed. It can be used as a reference for the application and quality evaluation of national radiation data.
