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.

Diffusion parameters of thermal neutrons in water were determined from diffusion length measurements in 22 boron-poisoned aqueous solutions. A uniform plane source of thermal neutrons and a parallelepipedal polymethyl methacrylate container having a buckling of B2 = 9.1 × 10−2 cm−2 were used. The derived values of the diffusion parameters of thermal neutrons in water at 22 °C are These results are found to be in good agreement with Doming's recent calculations.
