In this paper, the energy resolution for broad X-ray beams of Gas Proportional Scintillation Counters with medium to large size windows, parallel grids and no focusing system is discussed. the variation of the pulse amplitude with the radial distance is calculated for several distances, d (taken from the bottom of the scintillation region to the photomultiplier's photocathode), in the 0 to 50mm range and compared with experimental results. It is shown that for a 2 inch photomultiplier d distances from 10 to 20mm, commonly used in the detector designs, represent a worst case situation.
