Activation Analysis by Short-Life Nuclides. I. Determination of Hafnium in Zirconium by Hafnium-179 m.

Nonferrous Metallurgy

“…The procedure requires only 20 minutes and eliminates difficult and tedious separations required in previous methods. Jennings determined trace amounts of copper in zone-refined indium arsenide by squarewave polarography (188). His method is sensitive to 0.1 p.p.m.…”

Nucleonics

“…Workers have determined low concentrations of hafnium in reactor grade zirconium using the long-lived hafnium isotopes as well as the shortlived activities (600,686). Activation analysis has also been used to determine the solubility of tantalum in sodium in the part per million range (357).…”
