Oddity: Both the Brookhaven tables list the prevalent isotope Se80 as STABLE, but its box, instead of black, is "beta decay magenta" with a decay mode of 2β- . Japan Atomic Energy Agency just says >.5 Gy. Wikipedia flatly says stable, which is interesting because they list no stable isotopes of tungsten, but ascribe quintillion year half-lives to five of them. What gives? --rwg Isn't it odd of JAEA to lump U235 with C12, stabilitywise? Hmm, my dandruff shampoo may leave me with a radiation deficiency.

Thanks Ed! I had rejected that because it wasn't an actual image, lacked Z labeling, but mostly because I hadn't thought to click on Decay Mode to override the defaulted Half Life, which is so colored as to make it almost impossible to notice the instability of technetium. I subsequently found http://elementdata.net/chart_of_the_nuclides.jpg , but Mike Stay's https://upload.wikimedia.org/wikipedia/commons/9/92/NuclideMap.PNG is exactly the ticket. Thanks, Mike! --Bill And here I thought SF stood for San Francisco.

Does anybody know where to find a full sized version of
