Error in Ra-226 half-life in "Decay chain(4n+2, Uranium series).svg"Edit
The half-life in this graphic (https://commons.wikimedia.org/wiki/File:Decay_chain%284n%2B2,_Uranium_series%29.svg) is currently written as "1.602Yr" when it should be "1,600Yr". 1600 years matches the NuDat2 database, ENDSF, and the wikipedia article on radium isotopes.
Other half-lives in the image are not consistent with NuDat2 either, e.g. Th234, Pa234m, ... Ideally they should all be changed to be consistent with a referenecable source such as NuDat2 http://www.nndc.bnl.gov/nudat2/chartNuc.jsp
Best wishes, Alex
