Some methods for measurement of radon and radon progeny are reviewed in this paper.(1)Filter method for the measurement of radon progeny. A general formula was developed for the filter method, which can be used conveniently. All the formula related with the filter method are the special cases of our formula and could be obtained by using a magnetic card and a TI-59 calculator.(2)Two-filter method for the measurement of radon. A general formula was developed for the two-filter method, which is a direct result of the formula given in ref. (12). J. W. Thomas' result could be obtained easily from it by using the reasonable diffusion coefficient.(3)Balloon method for the measurement of radon. Balloon method for the measurement of radon was developed in 1974. The air containing radon was taken into a nylon balloon with a sampling time t1 and sampling rate Q1. Radon progeny activity was removed by a filter. After a certain duration t2, the air was taken out from the ballon with the time t3. When air was taken out, it passed the another filter. The a counts on this filter in the time interval T1→T2 canbe calculated by a general formula. For one sampling, the measurement can be finished within 25 mins with the sensitivity of 0.01-0.005 pCi/1, which is much more sensitive than the two-filter method, and also, faster and more convenient.The calculated results are compared with the experimental values and the agreements are quite good.

本文概括了我们对氡及其子体测量方法的研究进展,主要有:(1) 滤膜法测氡子体。发展了一个滤膜法测氡子体的一般公式,现有文献中的各种有关公式均是其特例。它使用方便,只要一张TI-59型计算器磁卡,即可导得任意条件下的具体公式。(2) 双滤膜法测氡。作为上述公式的推论,导出了双滤膜法测氡的一般公式。依此可导得Thomas公式,并解决了Thomas采用扩散系数不合理的困难。(3) 气球法测氡。导得气球法测氡的一般公式,使我国独特发展的气球法(比双滤膜法灵敏度高、速度快)有了理论基础,省去了实验校刻工作,使其成为一个独立的测量方法。 文末把理论计算与实验结果作了比较。

Based on optimum linear filter theory, frequency responses of two filters, i.e. "matched filter" and "Wiener filter" are analysed and compared for separating regional-residual components of gravity or magnetic fields. The fact that "matched filtering" is only a particular case of general Wiener filtering is pointed out. On the other hand, the error of the two filters is compared with that of Wiener filter in general. Their limitations are shown by simple examples....
