We calculated theoretically the mass absorption coefficients for positrons emitted from the commonly used sources 22Na and 68Ge/68Ga in numerous materials. For this purpose, we used the tool kit GEANT4 which allows to generate the implantation profile. An excellent agreement between the experimental profile and the calculated one was achieved. The calculated values of the mass absorption coefficients coincide well with the experimental values determined by the DSIP method.
