In this paper, a new efficiency calibration scheme is proposed for the inhomogeneous adsorption column, in which the segment efficiencies modeled by the Monte Carlo toolkit Geant4 are weighted according to the fraction distributions of the adsorbed radioxenon based on the equilibrium adsorption theory. In order to verify the scheme, an experiment of efficiency calibration of HPGe detector by employing radon daughters was performed, and as a result the relative errors between the measured value and simulated value was less than ± 2.3%. This method developed in this paper is useful for the development of rapid test device of radioactive gas.
