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.

Four boreholes were drilled in the Iraqi Western Desert area, and many isotope injection experiments were carried out to determine the effective porosity, permeability, transmissibility, storage coefficient, and velocity of the underground water flow using 131I as a radioactive tracer. The results indicate that the critical hydrological parameters (effective porosity, permeability, transmissibility, and storage coefficient) of the aquifer and the quantity of the water are adequate to provide sufficient high-quality water suitable for economic utilization. The radioactive technique used in drawdown for permeability, transmissibility, and storage coefficient measurements is specific and gave good results, whereas the classical method might be subject to technical operation errors.
