title: Effective thickness of bulk samples in "close" measuring gamma-ray spectrometry.
abstract: Analyzing the experimentally evaluated self-attenuation correction coefficients needed in activity determination by means of gamma-ray spectrometry, the effective thicknesses of bulk samples of three shapes were evaluated. The effective thicknesses deduced significantly differ from the geometrical sample thicknesses in "close" measuring geometry.
