title = "The concept of virtual point detector for voluminous gamma detectors",
abstract = "The replacement of voluminous γ detectors by virtual point detectors allows simple interpolation or extrapolation of the efficiency of the detector with the source-detector distance. The distance between the virtual point detector and the detector's cap was found to depend for cylindrical detectors on both the radius and the height of the detector. This concept can be used also for disk sources and explains the variation of the efficiency of cylindrical sources with the height of the cylinder. This effect was used to calculate the optimal dimensions for a cylindrical source with constant volume.",
