| Summary: | "OPb clearly indicate particle concentrations, 238PU/239,240puactivity ratios were measured in water 238PU/239,24OPu) have been utilized to determine the sources activity ratios suggest all of the Pu entering into and transport of anthropogenic pollutants. Water soluble Arctic (Pechora, Kara, Laptev, and East Siberian Seas) in column. River water residence times for the surface and column. To elucidate the sources of Pu and 131CS to the Concentrations and inventories of Pu and "'Cs as well control radioactive and other pollutants entering surface controlled by the particle concentrations in the water determine the water mass movements as well as residence time emanating from estuarine sediments . 21lpU/219,24OPu entering the Kara Sea. Fallout. The Pu concentrations are also primarily for scavenging studies. The inventories of Pu and for the estimation of the residence time of river water Hague nuclear reprocessing plants, and a riverine source influenced by resuspension, ice melt, and continental Natural and anthropogenic radionuclides have been widely used of water masses. This will help to define the processes one year and 30 years, respectively. order to better understand scavenging within the water particulate phases) from the marginal seas of the Russian radiocesium and activity ratios of Pu (such as radionuclides such as ... Ph and 214 Th have been employed related to estuarine mixing over the continental shelf which runoff, primarily control the removal of these nuclides. samples. Concentrations of Ra isotopes were also determined shelf waters by way of Siberian rivers is from Global shelf. an oceanic source, likely from Sellafield and La sources of Pu and "'Cs to the waters over the Siberian study area, Pu and "'Cs concentrations and subsurface waters of the Kara Sea were estimated, the activity ratio of "IpU/219,l4OpU suggest two main the marine environment. In this study, particle-reactive The model-derived scavenging parameters for 114 Th and to trace the sources and fate of radioactive pollutants in tracers such as Ra isotopes and radiocesium have been used to using2l'Ra/22'Ra activity ratios, to be on the order of waters of the Arctic Ocean. 21OPb and 214 Th concentrations were measured in a suite of water samples (dissolved and |
