A mathematical model to describe the radon motion outside the surface of rocks during the sustained stress on the rocks has been established and an experimental device for monitoring changes of radon concentration has been designed. The theoretic and experimental results show that there is a negative correlation between radon concentration emitted from granite and sandstone rock specimens and the axial pressure loaded on the rock specimens. The maximum error of the radon concentration between theoretic and experimental results is about 10.74%.
