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.

Application of computerized tomography (CT) in two-phase flows has been discussed in the existing literature. Development of a fast, but simple, algorithm for reconstructing the density p or the absorption coefficient µ is attempted. The algorithm, involving radial polynomials (RAP), has been tested using simulated data for radially symmetric bubbly and annular two-phase flows. The RAP algorithm can also be applied in nonsymmetric flow situations, provided the information required is the cross-sectionally averaged density. The results indicate RAP to be a fast and accurate method for CT reconstructions involving an air-water flow system.
