Half-life is 17 Million Years

The half-life of I-129 is 17 million years as per the most recent estimate - the primary source for this number is Holden, N.E. (1990) Total half-lives for selected nuclides. Pure and Applied Chemistry, 62, 941-958. Yes, 1990 is the most recent estimate. No, I have no idea why the chart of the nuclides is still using the really old 15.3 My value. Cosmochemistry, a textbook by McSween and Huss, published in 2010, gives a good overview of the 129 I-Xe chronometer and gives strong support to the use of the value published in Holden (1990). I don't feel like learning how to edit sources this evening, so maybe somebody in the distant future can fix the page to align with current science. — Preceding unsigned comment added by 198.84.233.183 (talk) 05:12, 18 October 2013 (UTC)[reply]
