Talk:Isotope lists, 49-72

123Te is not radioactive (guys who claimed that beta decay of this nuclide was found then disclaimed their result).
124Xe is not radioactive, the number 1.6e+14 a is just the lower limit on half life.
142Ce is not radioactive, the number 5e+16 a is just the lower limit on half life.
149Sm is not radioactive, the number 2e+15 a is just the lower limit on half life.
151Eu is alpha active (the recent result, 2007) with half life of 7e+18 a, %α=100. --V1adis1av (talk) 23:18, 28 February 2008 (UTC)
