Rapid Microdetermination of Dysprosium in Terbium Oxide by Neutron Activation and γ-Ray Spectrometry
Journal Article

· Bulletin of the Chemical Society of Japan
Dysprosium in terbium oxide powder was determined by a simple method involving 1 min irradiation with pile neutrons of 3 x 1011 n/cm2/sec and repeated gamma -ray spectrometry using a 2 in. thick sodium-iodide crystal attached to a 258-channel pulse-height analyzer. Both interferences and the self- shielding effect were negligible. The coefficient of variation of singie analyses was 5.2% for a 24 mg sample of 48 ppm dysprosium content.
