Angle does not store parameters of the radioactive source in dedicated files (as energies and materials), but it includes source data as a part of the reference efficiency curve, calculation parameters and calculation results data.
Source parameters consist of two attributes, “radius” and “height” and the specification of the source material:
<source radius=float0 height=float0> <material Source material specification /> </source>
Material is specified as in the way defined in the Material data section. If the source height is equal to zero (i.e. in case of “disk” or “point sources”) a material does not need to be specified.
<source radius="74.76" height="49.3"> <material name="Water" /> </source>
