Relative fission product yields in the USGS TRIGA MARK I reactor

Controlling Extraction of Rare Earth Elements Using Functionalized Aryl-vinyl Phosphonic Acid Esters

“…Aqueous solutions were prepared from 70% nitric acid and 18.2 MΩ water and standardized by titration with NaOH to the phenolphthalein end point. Radioactive 152,154 Eu was produced by neutron activation of solid Eu 2 O 3 using the U.S. Geological Survey TRIGA reactor 34 and was then dissolved in nitric acid and found to be radiochemically pure by γ spectroscopy. Aliquots of this stock solution were evaporated to dryness and redissolved in nitric acid to prepare radiotracer solutions of 152,154 Eu for these experiments.…”
