Based on a lerge amount of data in Radon-measuing, a formula has been put forward, with which the similarity between Radon-measuring data can be described, and the false abnormalities can be found in the Radon-measuring curves.

Some problems and methods about instulling the gas separation device of the digital measure Rn emanometry were introduced in this paper.

The determination of location and range of mined-out area by using Radon measurement method, according to the analysis of the geophysical and geochemical characteristics of radon, is discussed in this paper, and the satisfactory result was obtained when it was applied in Zhangcun coal mine.

Radon measurement is a geophysical radiometry.

In the program of reconnaissance of geothermy in Wang village Qi County,we tried to combine Rn measurement and magnetic prospecting to avoid undetermined or multiple explanation in the case of only one method was used to obtain more precise result.

This paper describes the basic principle of radon gas survey and, with an analysis of the result of radon survey performed over the known blocks in the Xiazhuang granite uranium orefield, illustrates the effectiveness of such survey in the prospecting for deep concealed uranium deposits.

Identifying the site of granite uranium deposit with radon survey and soil-natural themoluminescence survey——a case study of Xiazhuang granite uranium field;

Application of radon survey to engineering geology;

In order to eliminate the statistical fluctuation and random interference,this paper uses the multi-scale wavelet decomposition to analyze radon survey data so that the abnormal respond to the deep uranium mineralization can be subtracted.
