Abstract

A certified reference material designed for the determination of 129I in seawater, IAEA-418 (Mediterranean Sea water) is described and the results of certification are presented. The median of 129I concentration with 95% confidence interval was chosen as the most reliable estimates of the true value. The median, given as the certified value, is 2.28 × 108 atom L-1 (95% confidence interval is (2.16-2.73) 108 atom L-1), or 3.19 × 10-7 Bq L-1 (95% confidence interval is (3.02-3.82) × 10 -7 Bq L-1). The material is intended to be used for standardization procedures applied in accelerator mass spectrometric laboratories. It is available in 1 L units and may be ordered via IAEA web side ( www.iaea.org ). © 2010 Akadémiai Kiadó, Budapest, Hungary.
