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.

The safety and credibility of boraflex, a neutron absorbing material widely used in the spent-fuel storage assembly, has been analyzed from a nuclear point of view. The nuclear heating (absorbed dose) rate and the neutron-induced radioactivity for the boraflex under a typical nuclear environment were calculated. The result showed that in a normal condition, the total absorbed dose for the boraflex was mainly due to the decay photons originating from the spent fuel and compatible with the dose limit prescribed in the literature. Furthermore, the induced radioactivity level for the boraflex after 30 yr (the expected lifetime of the storage rack) of spent-fuel neutron irradiation was well below the limit stated in 10CFR61.55, so it can be classified as Class A waste.
