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.

Parameters of a 124Sb-Be neutron source used for “on-stream” elemental analysis are described. An analytical study of a basic on-stream system is given and some preliminary experimental results are compared with the calculations. The system consists of an irradiation chamber containing the 124Sb-Be source and a counting chamber with a delay line connecting the two. The unit can handle up to 7200 Ci of 124Sb which gives a thermal-neutron flux of ∼2 × 108 n/(cm2 sec) on the inside surface of the cylindrical irradiation chamber. A 13-liter irradiation chamber was found to be an optimum volume for all but very short-lived isotopes. In separate solutions, the elements Al, Hf, In, Mn, Ag, and V can be analyzed repetitively in 5 to 10 min cycles at <100 ppm using a 2.7-liter counting chamber. Calculated sensitivities for a number of elements and actual measured values for Al, Cl, Co, Hf, Mg, Na, and Cu are given.
