Nuclear News 40 Under 40: The wait is over
Following the enthusiastic response from the nuclear community in 2024 for the inaugural NN 40 Under 40, the Nuclear News team knew we had to take up the difficult task in 2025 of turning it into an annual event—though there was plenty of uncertainty as to how the community would receive a second iteration this year. That uncertainty was unfounded, clearly, as the tight-knit nuclear community embraced the chance to celebrate its up-and-coming generation of scientists, engineers, and policy makers who are working to grow the influence of this oft-misunderstood technology.

Samples of tritiated LaNi4.15Al0.85 (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.
