摘要： 借助统计学的方法对辐射监测结果进行统计和分析,是检验数据合理性的一种有效质量保证手段。在广东南部随机选取了A地区开展土壤中天然放射性核素的活度浓度调查,并借助秩相关系数法对监测数据进行了统计学检验。结果表明,本次调查土壤中天然放射性核素活度浓度属于正常环境水平。由于²³⁸U与²²⁶Ra、²¹⁰Po同属于铀系,在天然土壤中处于平衡状态,秩相关系数法结果表明²²⁶Ra、²¹⁰Po监测结果随²³⁸U的监测结果变化趋势具有显著意义,与理论预期相符,进一步验证了监测结果的合理性。

Abstract: Statistics and analysis of radiation monitoring results using statistical methods are effective quality assurance means to check the reasonableness of data. Monitoring of activity concentrations of natural nuclides in soil was carried out in area A of southern Guangdong, which was randomly selected. The monitoring data were statistically examined using the rank correlation coefficient method. The results showed that the activity concentrations of natural nuclides in soil for this survey belonged to the normal environmental level. Since ²³⁸U ²²⁶Ra and ²¹⁰Po belong to the same uranium family and are in equilibrium in natural soil, the results of the rank correlation coefficient method show that the trend of the monitoring results of ²²⁶Ra and ²¹⁰Po with the monitoring results of ²³⁸U are of great significance, which are in line with the theoretical expectation, and further verified the reasonableness of the monitoring results.

Key words: radiation protection, rank correlation coefficient, natural nuclides, statistical examine
