Abstract: The surface homogeneity of planar sources used to calibrate contamination detectors is important considering that their dimensions are bigger than the most kind of detectors tested and the positioning in relation to the source may vary in each measurement. Using a special pancake detector the counting efficiency of alpha and beta sources was measured in several positioning covering all area of the sources. The (14)C source showed the worse performance and the (241)Am source showed the best behavior.<br /> (Copyright 2009 Elsevier Ltd. All rights reserved.)
