Abstract
This study describes the fabrication of 57Co point sources utilizing the metal sorption properties of amidoxime functionalized PAN-PVDF beads. PAN-PVDF beads were synthesized by phase inversion, functionalized and characterized by FT-IR spectroscopy. Uptake of 57Co on amidoxime-PAN-PVDF beads was investigated by optimizing the experimental parameters. The optimized procedure was employed for fabrication of 57Co point sources. Distribution pattern of 57Co on the source core was confirmed by autoradiography. SEM and EDS analyses of inactive Co loaded beads were performed. A simple procedure for stable loading of 57Co onto PAN-PVDF beads could be standardized. The method could be of potential utility for fabrication of 57Co point for calibration purposes after extensive quality control studies.
