A method that does not require changing wire screens is proposed to achieve continuous measurement of unattached radon progeny. This method uses cumulative activity functions to deduct the influence of previous measurements from the current measurements on the sampling wire screen. The continuous measurement method was compared with a single measurement method, including relative deviations, uncertainties, and fluctuation range, which indicated the effectiveness of the cumulative activity functions applied to the continuous measurement method. The establishment of a continuous measurement method based on alpha spectroscopy provides technical support for the monitoring device.

游离氡子体连续测量方法的研究。

提出了一种不需要更换丝网的方法来实现对未附着氡气子体的连续测量。该方法使用累积活度函数从采样线屏蔽上的当前测量值中扣除先前测量值的影响。将连续测量方法与单一测量方法进行比较，包括相对偏差、不确定性和波动范围，表明累积活度函数应用于连续测量方法的有效性。基于α能谱的连续测量方法的建立为监测装置提供了技术支撑。
