On the use of the instrument s K-value in ground-water radon content observations;

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.

he results of the radon measurement are affected by many factors, for instance, thehumiduty of the soil, the temperature in the detecting hole, climate, etc.

The results of ESR dating show that the fault is the late Pleistocene tectonic structure,while the on-site radon measurement shows that the ratio of the fault pulse peak value to the background value is relatively large and with relatively weak level of healing.
