Dealing with volumetric radioactive sources of diverse matrices and sizes is an inevitable task for any gamma spectrometry laboratory. This multiplicity in the source configuration is required to be measured make creating a standard source for each source configuration infeasible. One way to reduce the necessary number of standard sources is to use the self-shielding factor (at a certain energy defined as the fraction of the photon engendered at such energy that is needed to escape the source intact) to allow the use of sample sources of different matrices and sizes than the standard source. This work is concerned with the direct mathematical calculation of the self-shielding factor of cylindrical sources of various radii and heights in the energy range from 10 keV to 1 MeV with a NaCl matrix.
