Its threshold is 9.137 5325 1451 18 MeV. The half-life of I-126 is 13.023d. Iodine is a monoisotopic 5325 1451 19 element. The main gamma ray energies of I-126 are 388.6keV 5325 1451 20 and 666.4keV with branch ratios of 34.1 percent and 33.1 percent 5325 1451 21 respectively. In order to get reasonable results, the necessary 5325 1451 22 adjustment was made first for the collected data. Then the 5325 1451 23 evaluation was performed by spline fitting procedure. The 5325 1451 24 uncertainties were derived from experimental errors and 5325 1451 25 the consideration of systematics. 5325 1451 26 5325 1451 27 Evaluation documentation: Zhao Wenrong. 5325 1451 28
