Mathematical efficiency calibration in gamma spectroscopy
-
S. Kaminski
Abstract
Mathematical efficiency calibration with the LabSOCS software was introduced for two detectors in the measurement laboratory of the Central Safety Department of Forschungszentrum Karlsruhe. In the present contribution, conventional efficiency calibration of gamma spectroscopy systems and mathematical efficiency calibration with LabSOCS are compared with respect to their performance, uncertainties, expenses, and results. It is reported about the experience gained, and the advantages and disadvantages of both methods of efficiency calibration are listed. The results allow the conclusion to be drawn that mathematical efficiency calibration is a real alternative to conventional efficiency calibration of gamma spectroscopy systems as obtained by measurements of mixed gamma ray standard sources.
Abstract
Die mathematische Wirkungsgradkalibrierung von Gammaspektrometern mit der Software LabSOCS wurde im Messlabor der Hauptabteilung Sicherheit im Forschungszentrum Karlsruhe für zwei Detektoren eingeführt. In diesem Beitrag werden die konventionelle Effizienzkalibrierung von Gammaspektrometern und die mathematische Effizienzkalibrierung mit der Software LabSOCS bezüglich Durchführung, Unsicherheiten, Aufwendungen und Ergebnissen miteinander verglichen. Ein Erfahrungsbericht ist wiedergegeben und die Vor- und Nachteile der beiden Methoden der Effizienzkalibrierung werden aufgeführt. Zusammenfassend kann gesagt werden, dass die mathematische Wirkungsgradkalibrierung mit LabSOCS eine echte Alternative darstellt zur herkömmlichen Wirkungsgradkalibrierung von Gammaspektrometern durch Messungen von Referenzlösungen.
