New analytical approach to calibrate the co-axial HPGe detectors including correction for source matrix self-attenuation.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Badawi MS, Gouda MM, Nafee SS, El-Khatib AM, El-Mallah EA.
PMID: 23023386
Appl Radiat Isot. 2012 Dec;70(12):2661-8. doi: 10.1016/j.apradiso.2012.08.014. Epub 2012 Aug 31.

To calibrate the co-axial HPGe semiconductor detectors, we introduce a new theoretical approach based on the Direct Statistical method proposed by Selim and Abbas (1995, 1996) to calculate the full-energy peak efficiency for cylindrical detectors. The present method depends...
