Inkjet droplets of radioactive material enable quick, precise testing at NIST
Researchers at the National Institute of Standards and Technology have developed a technique called cryogenic decay energy spectrometry capable of detecting single radioactive decay events from tiny material samples and simultaneously identifying the atoms involved. In time, the technology could replace characterization tasks that have taken months and could support rapid, accurate radiopharmaceutical development and used nuclear fuel recycling, according to an article published on July 8 by NIST.

In a basic study on reducing a conventional atmospheric detritiation system (ADS) to a small one, performances of H2(+HT), H2O(+HTO), and N2 (or air) permeating through a gas separation membrane (GSM) module were numerically analyzed. The calculations were carried out in (3 × 2 + 1) patterns of cross, countercurrent, and cocurrent flows based on the differential and plate models and the complete mixing flow. Previous experimental results of the H2/H2O/N2(air) three-component system were found to be well correlated by the differential cross-flow model. Applications of the GSM to the ADS were investigated, and the effectiveness of using the GSM in place of the first detritiation system of the ADS was discussed.
