Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Holmium. Additional text was taken directly from the Elements database 20001107 (via dict.org) and from WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

Magnetic Properties

In the introduction it states that Holmium has the highest magnetic permeability of any element and is there element and therefore is used for the polepieces of the strongest static magnets. It should say highest magnetic saturation moment. It is the moment rather than the permeability that is reason it is used in pole pieces for "strong" synthetic magnets. In the section Application Also magnetic strengthis a poorly defined quantity, it would be better to use magnetic moment or magnetic saturation moment

Y-90 alternative

Ho-166 is an alternative to Y-90 in injected microspheres based beta-radiation therapy (SIRT / TARE) for inoperable liver cancer patients. Ho-166 is produced commercially by Terumo (formerly Quirem) in Belgium. Because of its short half-life (28.6 hours) causing difficulties with long-distance transportation, it is only used in Europe but not USA, which uses Y-90 sourced from Canada instead. 94.21.160.64 (talk) 21:28, 2 May 2023 (UTC)[reply]
