连续、自动测量地下水氡的一种α方法

A α-METHOD FOR CONTINUOUS AND AUTOMATIC MEASUREMENT OF RADON IN GROUND WATER

摘要:

本文介绍了一种利用气-水相平衡原理实现连续、自动监测地下水氡浓度的新方法。推导出了该方法的数学表达式,对该方法的灵敏度、时间响应等特性作了讨论,并与利用该原理研制的水氡测量仪的测量结果进行比较。结果表明,这个新方法能够满足地震预报和地质领域测氡的要求。

Abstract:

This paper presents a new method by which the density of radon in ground water could be continuously and automatically measured on the basis of Gas-Water phase equilibrium principle of radon. In the paper the author deduces the mathematics expression for the method, discusses its sensibility and time response etc., and compares the theory with experimental results attained by water-radon measuring apparatus based on this principle. The results show that this new method can meet with the requirments of observation of radon in earthquake prediction and geological circles.
