Abstract
Abstract Steady state diffusion is characterized by a constant concentration gradient. It is obtained by imposing a limited solubility on the compound of interest and offers the possibility of an appreciable reduction of the emission(‐rate) from a waste body. The principle of steady state diffusion and its application to four limiting cases of practical interest are surveyed. In addition, the combination of a waste body with a surrounding barrier layer is considered. By comparing steady state diffusion to the non‐steady situation, its advantage factor can be derived. Similarly, the use of a barrier is defined in terms of an advantage factor. Radiotracers provide an efficient way of measuring the effective diffusion coefficients and the emission(‐rate) from a waste body in laboratory or field experiments.
