Abstract: Iodine environmental measurements have consistently been validated in the literature using the standard material IAEA-375, soil collected approximately 160 miles northeast of Chernobyl, which is currently the only soil/sediment material with a certified <superscript>129</superscript> I activity. IAEA-375 has not been available for purchase since approximately 2010. Two other standard materials that are available (NIST SRM 4354, freshwater lake sediment and NIST SRM 4357, ocean sediment) have certified activities for a variety of radionuclides but not for <superscript>129</superscript> I. This paper reports a comparison of TIMS and AMS data for all three standards.<br /> (Copyright © 2017. Published by Elsevier Ltd.)
