An algorithm for computation of source-to-site distance distributions is proposed, implemented in VBA and verified. It consists of two stages: first a point cloud is generated inside the source area, and then the distribution of distances from each point to the site is computed. The distribution is expressed as a histogram for user-defined ranges between the minimum and the maximum distance.
