A key assumption here is that the source is represented as a single point source then spherical shield layers around it.
In traditional point kernel codes the source is broken into a set of point kernels and the result is the sum of all the kernels, e.g. for a line surface or volume source.
The documentation source page just discusses the source energy, should make it clearer it is represented as a single point source.
