Determination of In Vitro Lung Solubility and Intake-to-dose Conversion Factor for Tritiated Lanthanum Nickel Aluminum Alloy

Samples of tritiated LaNi 4.15 Al 0.85 (LANA.85) and 13X zeolite were analyzed to obtain particle size distributions and tritium evolution rates in a simulated lung environment. This information was used to calculate intake-to-dose conversion factors (DCFs), which estimate the committed effective dose (CED) a worker would receive after inhaling either tritiated particulate. The DCFs for tritiated LANA.85 and 13X particulate with a default activity mean aerodynamic diameter (AMAD) of 5 μm were determined to be 1.01E-11 Sv/Bq and 1.11E-11 Sv/Bq, respectively. These results are comparable to that of HTO, 1.8E-11 Sv/Bq, indicating that urine bioassay results can conservatively estimate the dose delivered if the worker was exposed to any mixture of HTO, LANA.85, or 13X.
