| 为确保单闪烁室流气静态法准确测量222Rn/220Rn浓度,进行了222Rn、220Rn刻度系数的理论研究,讨论了采样流率对刻度系数的影响,通过理论公式计算得到了刻度系数的理论值,并与标准刻度后的实验值进行比较.结果表明刻度系数的实验值和理论值是一致的,偏差在5%以内,确保了222Rn、220Rn刻度系数实验值的准确性,从而确保单闪烁室流气静态法的可靠性. |
| 英文摘要: |
| For accurate measurements of radon/thoron concentrations with a gas-through and static time-delay method using a single scintillation cell,a theoretical study of radon/thoron calibration factors was carried out and the influences of sampling flow rate on calibration factors were discussed.The theoretical values of calibration factors were calculated by theoretical formulas and compared with the experimental values after standard calibration.The results show that the experimental values are in good agreement with the theoretical values,and the deviations are less than 5%.The accuracy of experimental values of radon/thoron calibration factors can be ensured,so as to ensure the reliability of the gas-through and static time-delay method with a single scintillation cell. |
