Reference Data Repository[edit]

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.

St. Leibowitz, deliver us from the rain of cobalt![edit]

The russian's failed Phobos-Grunt giant Mars spaceprobe has a 11kg canister of Cobalt-57 on-board, probably for thermo-electric generation. It is about to impact Earth during January 2012, which makes the "Maya domesday" hypers pretty happy. The article could explain what are the expected consequences, if that co-57 canister hits a populated area. 82.131.210.163 (talk) 09:42, 22 December 2011 (UTC)
