摘要
介绍放射性平行样品服从的统计分布,据此提出平行样品结果统计检验方法,用该方法对1组平行样品结果做统计检验,并与计算标准偏差的检验方法作比对。结果表明,虽然2种检验方法得出了相反的结论,但统计检验方法的结果更符合放射性测量的规律。
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.
