Abstract Research was performed to assess the feasibility of barrier membrane substances, for use within mining or associated high risk environments, in restricting the diffusion transport of radon gas. Specific tests were conducted, both within laboratory and in situ environments, to determine radon gas concentration ratios across a barrier of interest and emanation rate variation resulting from application of such materials. Several materials have been demonstrat ed to be effective in restricting the emanation ofradon gas into initially radon-free environments. One liquid material shows particularly good promise upon consideration of ideal radon barrier criteria.
