    Tracing variability in the iodine isotopes and species along surface water transect from the North Sea to the Canary Islands2016In: Journal of Radioanalytical and Nuclear Chemistry, ISSN 0236-5731, E-ISSN 1588-2780, Vol. 307, no 2, p. 1407-1412Article in journal (Refereed)
    Abstract [en]

    A complete transect of surface water samples from the North Sea to the Canary Islands was collected during a continuous period in 2010. The samples were analyzed for total I-129 and I-127 isotopes and their iodide and iodate species. The results indicate a large variability in the total I-129 and its species along the transect, whereas less change and variation are observed for the total I-127 and its species. Transport of I-129 fromthe western English Channel via Biscay Bay is the main source of I-129 in the northeastern Atlantic Ocean.

    Radioactive I-129 in surface water of the Celtic Sea2014In: Journal of Radioanalytical and Nuclear Chemistry, ISSN 0236-5731, E-ISSN 1588-2780, Vol. 299, no 1, p. 249-253Article in journal (Refereed)
    Abstract [en]

    Relatively large amounts of radioactive iodine I-129 (T (1/2) = 15.7 Ma) have been documented in seawater such as the English Channel, the Irish Sea and the North Sea. Data on the concentration of the iodine isotopes in waters of the Celtic Sea are missing. Aiming to provide first I-129 data in the Celtic Sea and compare them with levels in the other close-by seawater bodies, surface seawater samples were analyzed for the determination of I-127 and I-129 concentrations. The results revealed a high level of I-129 in these waters and suggest strong influence by liquid discharges from La Hague and Sellafield reprocessing facilities. I-127 concentrations are rather constant while the I-129/I-127 ratio reaches up to 2.8 x 10(-8) (ranging from 10(-10) to 10(-8)), which is 2-4 orders of magnitude higher than pre-nuclear era natural level. Transport of I-129 to the Celtic Sea is difficult to depict accurately since available data are sparse. Most likely, however, that discharges originated from La Hague may have more influence on the Celtic Sea I-129 concentrations than the Sellafield. Comprehensive surface water and depth profiles I-129 data will be needed in the future for assessment of environmental impact in the region.

    Speciation analysis of I-129 in seawater using coprecipitation and accelerator mass spectrometry and its applications2017In: Journal of Radioanalytical and Nuclear Chemistry, ISSN 0236-5731, E-ISSN 1588-2780, Vol. 311, no 1, p. 833-841Article in journal (Refereed)
    Abstract [en]

    Speciation analysis of long-lived I-129 in seawater can provide useful information on the source of water masses. This paper presents an improved method for speciation analysis of I-129 based on coprecipitation of iodide as AgI with Ag2SO3 and AgCl. By adding a small amount of I-127 carrier, the separation efficiency of iodine species and the accuracy and precision of I-129 measurement are remarkably improved. I-129 species in depth profiles of seawater from the Antarctic were analyzed for investigation of water circulation in the Antarctic.
