A revision factor to the Cutshall self-attenuation correction in Pb-210 gamma-spectrometry measurements

摘要

The Cutshall transmission method of determination of self-attenuation correction in Pb-210 measurements by gamma-spectrometry gives the results burdened with errors of up to 10%. The author proposes introducing into the Cutshall correction C-s,C-Cuts an additional revision factor CC,cuts to eliminate errors. The proposed formula of the revision factor describes the CCs,Cuts value depending on the experimentally obtained C-s,C-Cuts correction. Formula holds true in wide ranges of the measurement geometries and linear attenuation coefficients of both the standard and the sample. (C) 2015 Elsevier Ltd. All rights reserved.
