Container effects in /sup 56/Mn sources for iron determination in the human body by NRS technique
Iron overloads in liver and heart are detected in vivo by nuclear resonant scattering (NRS) technique. The method is based on the resonant scattering of 847 keV gamma ray from the first nuclear level in /sup 56/Fe. The source of radiation is provided by /sup 56/MnCl/sub 2/ maintained in a gaseous phase in an evacuated quartz vial at 1030/sup 0/C. It was observed that the time dependent NRS yield, from an iron slab, differed appreciably from the 2.58 hr. half-life of /sup 56/Mn. Inasmuch as the NRS system responds only to the source in the gaseous phase, the discrepancy is attributed to the interaction between the gaseous source and the walls of the vial. Fused silica vials and fused quartz vials demonstrate entirely different time behavior.
