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.

A pseudoline source is realized by using an accelerator-based deuterium-tritium point-neutron source. The pseudoline source is obtained by time averaging of the continuously moving point source or by superposition of the finely distributed point sources. The line source is utilized for fusion blanket neutronics experiments with an annular geometry to simulate a part of a tokamak reactor. The source neutron characteristics are measured for two operational modes for the line source: the continuous and the stepwise modes, with activation foil and NE-213 detectors, respectively. The neutron source characteristic is calculated by a Monte Carlo code to give a source condition for a successive calculational analysis of the annular blanket experiment. The reliability of the Monte Carlo calculation is confirmed by comparison with the measured source characteristics.
