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.

Three-dimensional (3-D) neutron-gamma transport calculations have been performed for the LIBRA-SP chamber with detailed geometrical modeling and results were compared to results based on one-dimensional (1-D) calculations. The overall tritium breeding ratio is 1.396. This is only 3% lower than the value predicted from the 1-D results. The overall reactor energy multiplication is 1.157 which is only 2% lower than the value estimated from the 1-D calculations. Larger differences were observed in the local heating and damage results obtained from the 1-D and 3-D calculations.
