title: The examination of source distribution in a large sample by Monte Carlo simulation.
abstract: In this work, realistic Monte Carlo simulations were carried out for several distributions of activity in a waste drum to observe the dependence of the efficiency on the source distribution and to test whether the efficiency can be correlated with the shape of the spectra.
