- Abstract
- Estimates of the committed effective dose (E-50) from an intake of a radionuclide strongly depends on several dosimetric parameters such as the intake pathway, f(1) value, the absorption type, activity median aerodynamic diameter and the time after an intake. A misuse of the dosimetric parameters can result in a significant error in the evaluated value of a committed effective dose. In order to reduce the potential error and to get optimised values of E-50, better bioassay methods and better (or worse) bioassay measurement times due to the uncertain dosimetric parameters were suggested for the various radionuclides, including Co-57, Co-58, Co-60, I-131, Cs-134, Cs-137, Sr-89, Sr-90, P-32 and U-235. This strategy was applied for the case of multiple unknown parameters as well as a single unknown parameter and provided the committed effective doses with the least potential error.
