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 numerical procedure for the calculation of thermal diffusion lengths directly from the formalism of Hurwitz and Nelkin is described. The technique is used to compute diffusion lengths for several plastic moderated assemblies, using the mass 1, free proton energy exchange kernel. Agreement of the calculated diffusion lengths with experiment is excellent.
