This article is part of Wikipedia:Wikiproject Isotopes. Please keep style and phrasings consistent across the set of pages. For later reference and improved reliability, data from all considered multiple sources is collected here. References are denoted by these letters:

A 729, pp. 3-128 (2003). — Where this source indicates a speculative value, the # mark is also applied to values with weak assignment arguments from other sources, if grouped together. An asterisk after the A means that a comment of some importance may be available in the original.

Al-26 Entries are inconsistent
The infobox says Al-26 has positron, EC, and gamma decays, but the List of Isotopes lists only positron decay. This is inconsistent. If it does actually have 3 decay modes, the decay fractions should be listed. Pulu (talk) 17:47, 12 June 2019 (UTC)
