Abstract: Monitoring radioactive gas 37Ar is an important technique for the OnSite Inspection(OSI) of the Comprehensive Nuclear Test Ban Treaty (CTBT) verification regime. In order to establish a theoretical model that can be used to calculate the appearing time and radioactivity of 37Ar which transports to the ground after a nuclear explosion， the rock media in the test area is assumed to be a homogeneous porous media， without consideration of gas absorption by and release from the rock media. The seepage model in the porous media is used to calculate 37Ar transportation. Computational results give the time 37Ar leaks to the ground and the variation of its radioactivity with time．And we can analyze and consider the computational results when we have developed OSI noble gas monitoring systems and evaluated their effectiveness.
