| In environmental radioactive monitoring, parallel samples collection and analysis are important contents in quality assurance. In this paper, the statistical distribution of radioactive parallel sample results were introduced, and the statistical test method of radioactive parallel sample results were proposed. The statistical test was carried out on a pair of parallel sample results, and compared with the calculated standard deviation. The results showed that although the two methods gave the opposite conclusion, the result of statistical test method was more in accord with the radioactivity measurement. |
