Abstract: Philips Research Laboratories N. V. Philips' Gloeilampenfabrieken Eindhoven Netherlands Abstract: The shape of the self-absorption correction curve of -emitters is not universal but depends an the geometrical arrangement of the sample and counting device. This may explain why the correction factor defined by Hendler (1) is not always linearly related to the thickness of the sample. ___MH
