为适应新型连续测氡仪快速测氡的需要,探讨一种快速定值方法。采用新型连续测氡仪测定刻度因子,依据不同测量周期收集到218Po衰变产生的α粒子数,建立相应的衰变关系式。测量时无须多次测量,利用关系式即可快速定值。实验表明:该快速定值方法提高了新型连续测氡仪的定值效果,简化了定值过程。

In this study, a method is developed to meet the needs of rapid determination of novel continuous radon monitors. Novel continuous radon monitors are applied to determine the calibration coefficients. Corresponding decay relations are established in accordance with the alpha particles produced via 218Po decay with a measurement cycle of 60 minutes or different measurement cycles. Afterwards, with the relations there is no need to conduct the determination repeatedly. The results suggest that the rapid determination method improves the efficienc...
