In the
present work, we present a brief comment concerning the paper published by
Loussaief et al. 2007 (Nucl. Inst.
and Meth in Phys. Resh. A 580. 2007). The reference has used the multipole
expansion method to determine the photon flux and the dose distribution in the
vicinity of the Tunisian gamma irradiation facility. We have shown that the
multipole expansion is useless and wrong for the calculation of the photon flux
and the dose distribution in the vicinity of the CNSTN irradiator. We have also
determined the dose distribution in the vicinity of the same irradiator, using
a straightforward calculation, in order to show that we can abandon the multipole
expansion method I our case.
