چکیده
This report compiled all abstracts presented in the NKS Workshop on Radioanalytical Chemistry at Risø, Roskilde, Denmark in 2-6 Sept. 2013. Total 35 participants registered to the workshop, among them 18 from Sweden, 5 from Denmark, 3 from Finland, and 3 from Norway, there are also 6 participants from Germany, France, Slovenia, Korea, Turkey, and China. The workshop consists two part, 3 days lab practices and 2 days lectures/presentation. 3 lab practices were organized, i.e. (1) Radiochemical separation of Pu and ICP-MS measurement of Pu isotopes; (2) Radiochemical separation of Po and Ra and their alpha spectrometry measurement; and (3) Radiochemical separation of Fe, Ni, Sr and their LSC measurement. Among them, each participant can participate in 2 lab practices. 15 invited lectures are given by the experts in their specific fields, 8 oral and 6 poster presentations are given by the participants. The abstracts of all presentations are included in this report.

The ultratrace determination of iodine 129 in aqueous samples using the 7700x ICP-MS with oxygen reaction mode
Determination of the radionuclide iodine 129 using ICP-MS has been improved by the use of an Octopole Reaction System (ORS) ICP-MS, operated in oxygen cell mode. Oxygen reaction gas removes the background signal at m/z 129, which is due to the presence of Xe as an impurity in the Ar plasma gas and to the polyatomic ion IH2. NIST SRM standards with different 129I/127I ratios and at multiple conc...

Analytical chemistry of metal complexes with biomacromolecules based on the coupling of a high resolution separation technique with an element or species selective detection technique is critically discussed. The role of size-exclusion chromatography (SEC) with on-line atomic spectrometric detection is evaluated for the characterization of the metal distribution among the fractions of different...

In order to obtain the precise Pu isotope composition of Irish Sea water reference material issued by the International Atomic Energy Agency (IAEA-381), we analyzed the activities of (239)Pu, (240)Pu and the atom ratio of (240)Pu/(239)Pu by a highly sensitive isotope dilution SF-ICP-MS method combined with two-stage chromatographic separation and purification. With a mean chemical yield of 65% ...
