SOLUBILITY OF RADIONUCLIDES IN SIMULATED LUNG FLUID

摘要

The objective of this work was to assign FMS (fast, moderate and slow) absorption types to sitespecific radionuclides found at various Cameco facilities. Kinetics studies of dissolution of various uranium-bearing samples in simulated lung fluid were carried out. Dissolution parameters were determined and the samples were assigned to the FMS absorption types. A software program was developed for the determination of dissolution parameters. The assignments were based on criteria established in the International Commission on Radiological Protection (ICRP) Publication 71. The assignments were used to determine the internal radiation dose for workers.
