Coincidence summing corrections applied to volume sources

► Computation of coincidence summing corrections needs total and full-energy peak efficiencies. ► ETNA calculates coincidence summing corrective factors with two approaches for volume sources. ► The “simplified” calculation uses directly the efficiency of the volume source. ► The “complete” calculation performs integration over the volume source. ► Different geometrical cases are tested using both approaches to assess the resulting differences.
