Levels of radioactive contaminants in various Greenland environments have been assessed during 1999-2001. The source of 137Cs, 90Sr and (239,240)Pu in terrestrial and fresh water environments is mainly global fallout. In addition, the Chernobyl accid

Environmental samples (soil, sediment and lake water) in the Thule area (NW Greenland) have been studied to assess the contamination of radionuclides originating from a nuclear weapons accident (the Thule accident in 1968). Four lakes were chosen at

Soil samples from areas in Belarus, Russia and Sweden contaminated by the Chernobyl accident were analysed for (129)I by radiochemical neutron activation analysis, as well as for 137Cs by gamma-spectrometry. The atomic ratio of (129)I/137Cs in the up

Levels of radioactive caesium (137Cs) were determined in minke whales (Balaenoptera acutorostrata) from West Greenland, the Northeast Atlantic region and the North Sea. The sample consisted of muscle tissue from 135 minke whales caught in 1998 in 7 d

Environmental samples, such as seawater, seaweed, lake water, lake sediment and grass collected from the Baltic Sea area were analyzed for 129 I and 127 I by radiochemical neutron activation analysis. In 2000, the concentration of 129 I in the seawat

A procedure has been developed using 242 Pu as tracer for simultaneous determination of 237 Np and 239,240 Pu in environmental samples. The validity of the method has been demonstrated by ICPMS and α-spectroscopy for up to 10 gram soil and sediment,

In 1968 a U.S. B-52 bomber from USA with four nuclear weapons crashed on the sea ice near the Thule air base and contaminated the surroundings. Most of contamination was recovered during the cleanup program. However, some of the plutonium still remai

Based on a sediment vibro corer, a tool for the sampling of sub-seafloor groundwater aquifershas been developed and successfully deployed in a coastal area of the western Baltic. Thedevice was designed to obtain pure groundwater samples from coarse s

The radioactive contamination of the Techa–Iset rivers downstream from the MAYAK reservoirs has been determined by measurements of 90 Sr , 137 Cs and transuranic elements in floodplain soils and sorlake sediments. Empirical models for the spatial d
