An adequate mathematical description is essential for the design, calculation, and prediction of the output concentration and distribution of radionuclides in the sorbent bed over time. The theory of chromatography for non-radioactive adsorptives can now be considered detailed. However, its applications for radioactive gases are not as numerous and are generally limited to the simplest cases (stationary adsorption mode, linear isotherm). The present investigation improves upon the current model of the equilibrium adsorption layer by incorporating the radioactive decay of the adsorptive. At any given time, the complete description of the radionuclide distribution in the mobile and solid phase can be obtained through the resulting equation system, regardless of the type of adsorption isotherm.
