Abstract

Evaluated half-life values are given for the radionuclides 26Al, 40K, 53Mn, 60Fe, 87Rb, 93Zr, 98Tc, 107Pd, 129I, 135Cs, 146Sm, 176Lu, 182Hf, 187Re, 205Pb, 232Th, 235U, 238U, 244Pu, 247Cm. These were obtained from an analysis of published information up to 2001. These half-lives are used in geochronology and cosmochronology to determine different radiometric ages in the history of the earth, solar system and galaxy.
