Emanation of radon from rock minerals
Description
The mechanism of emanation of radon from terrestrial minerals and rocks is briefly discussed. Employing a technique which can locate nanometre-wide holes in materials, a network of very narrow (sub-micronic) openings/gaps within an individual mineral grain and between grains of different minerals has been observed. Radon enters this network by recoil-out from the solid walls, and is then subject to rapid transport by molecular diffusion in the air in the network. (author). 6 refs., 6 figs
