      A numerical solution of the model problem was used as an example to compare three different techniques of setting boundary conditions for calculations of electromagnetic fields produced by a gamma quantum point source located on a conducting surface. These techniques are baaed on representing electromagnetic fields as multipole decompositions beyond the source region. Their accuracies are compared by considering solutions on an external boundary of the computational region and one obtained for a problem where the external boundary is considerably far from the source.
