土壤中锶-90的测量不确定度评定

摘要

通过分析土壤中锶-90过程中的影响因素和计算公式中的有关参数，对不确定度进行评定，发现土壤中锶-90的分析主要受到仪器计数、重复性测量等因素影响。%The measurement data of Strontium-90 in soil were collected and the measurement uncertainty was evaluated. The results show that the main sources of the total uncertainty are detection count and repeatability of results.
