摘要

This work describes the procedure followed by the Laboratorio de Metrologia Nuclear (LMN) for the standardization of 55 Fe by the tracing method. This technique was applied using two radionuclides, which decay by the electron capture process followed by a prompt gamma-ray, namely Cr-51 and Mn-54, as tracers. The calibration was performed in a 4 pi beta-gamma coincidence system. The efficiency was obtained by selecting a gamma-ray window set at the 320 keV total absorption peak for Cr-51 and at 834 keV for Mn-54. (C) 2008 Elsevier Ltd. All rights reserved.
