X-Ray Fluorescence (XRF) Analysis with Ge-71 Excitation Source

摘要

The reactor-produced Ge-71 radioisotope is being used as XRF excitation source for the analysis of light and medium elements up to Cu. The simplicity in its preparation, handling and supply to the analytical centres for routine use overcomes significantly its short lifetime inconvenience (TI/2 = 11.3d). Some typical results of the analysis of crude oils, minor elements in quartz minerals and biological samples demonstrate the advantages of using the Ge-71 exitation source in XRF analysis.
