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.

The distribution function of alpha particles in toroidal magnetic systems is found. Energy losses are considered, and the pitch-angle scattering is modeled by a Bathagor-Gross-Krook operator. Stochastic diffusion is accounted for by assuming that toroidally trapped particles immediately exit the device. It is found that the energy loss of transit alpha particles in the presence of effective loss is not crucial, so the energy is well transferred into the bulk plasma.
