This method is based on the use of an active natural solid sample with several g-emissions (in our case, 226Ra) as the calibrating matrix for determining the full energy peak efficiency (FEPE) ec vs g-emission energy Eg and the sample height h in a counting cylindrical geometry. The 226Ra activity concentration is determined by a-particle spectrometry, a method that has previously been validatedapplication/pdf2 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Gamma-spectrometryEfficiency-calibrationSelf-absorptionSample-heightinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/S0969-806X(01)00290-0
