Monitor the levels of radionuclides (137Cs and 210Po) in selected fish and seafood species in the Norwegian and Barents Sea.
The aim of the CEEPRA (Collaboration Network on EuroArctic Environmental Radiation Protection and Research) project is establishment of a cooperation network in the EuroArctic region, cross-border exchange of knowledge and skills, improvement of emergency preparedness capabilities and risk assessments in case of nuclear accidents in the region as well as raising awareness and knowledge in the general public and stakeholders with respect to the nature, common challenges and associated risks in the area of nuclear safety, emergency preparedness and radioactivity in the environment. The project will study the current state of radioactive contamination in terrestrial and marine ecosystems in the EuroArctic region by examining environmental samples collected from the Finnish Lapland, Finnmark and Troms in Norway, the Kola Peninsula and the Barents Sea. The results will provide updated information on the present levels, occurrence and fate of radioactive substances in the Arctic environments and food chains. Special attention will be given to collection and analyses of natural products widely used by population in Finland, Russia and Norway, such as berries, mushrooms, fish and reindeer meat. The region-specific risk assessments will be carried out through modelling and investigation of long-term effects of potential nuclear accidents in the EuroArctic region and possible impacts on the region’s indigenous population, terrestrial and marine environments, reindeer husbandry, the natural product sector, tourism and industries. Open seminars for general public and target groups will be arranged in Finland, Russia and Norway during the project implementation period to provide relevant information on radioactivity-related issues and the status in the region.
The Norwegian Radiation Protection Authority is responsible for a network of 5 air filter stations. These collect air samples through high density filters which are analyzed weekly by gamma spectroscopy. The network was established in the early 80s and is continuously updated. The purpose of the network is to assess the levels and composition of emissions from incidents and accidents. In addition, with the help of meteorological data, possible sources of release may be identified.
The project monitors the artificial radioactivities in natural products in Finnish Lapland. The work mainly started after Chernobyl accident.
Vascular plants and mosses are also terrestrial bioindicators for radioactive fallout, The summer fodder of reindeer consist of 200- 300 vascular plants . Therefore vascular plants are an important link in the foodchain plants - reindeer/game - man. STUK has several permanent plant sampling sites, usually in the vicinity of the lichen plots. Only a few of of them are included in Finnish NIP. The results obtained are gammanuclide or occasionally also 90Sr concentrations, Bq/kg.
Part of the continuous nationwide monitoring of radionuclides in Finland. The dose rate monitoring network in Finnish Lapland comprise 32 automatic measurement stations (Finnish nation-wide monitoring network consists of about 257 stations equipped with GM tubes). Three of the stations are equipped with LaBr3-detectors measuring a gammaspectrum with 10 minute intervals. The network is intended for civilian defence and surveillance purposes, not for research. It is a good early warning system in radiation fallout situation. Every monitoring station have individual alarm level: 7 days average dose rate + 0.1 microSv/h. The dense network indicate also the extent of the radioactive contamination.
Lichens are the best terrestrial bioindicators for radioactive fallout and also the most important link in foodchain lichen - reindeer - man. Generally, Fenced permanent sampling plots are used to study the biological half-life of 137Cs in lichen. However, some of the STUKs sampling plots are unfenced which are subjected to grazing by reindeer. Start year: early 60's as a project of the Radiochemistry Department of University in Helsinki. Stuk's participation since 1975. Data are collected from 1961, 1980, 1982 or 1986, continuously every 3-5 years. Data processing/work-up and data archiving/reporting work are conducted from 1961, 1980, 1982. Continous data sets from 1986 to 2010.
Part of the continuous nationwide monitoring of radionuclides in Finland. STUK is responsible for monitoring of radioactivities in atmosphere. STUK operates a network of eight aerosol samplers from which three are located in Finnish, Lapland at Rovaniemi, Sodankylä and Ivalo. The sampling is done either weekly or bi-weekly. Gammaspectroscopic measurements are done in the laboratory in Rovaniemi. The lowest activities are detected at microBq/m3 level.
Elevated levels of 137Cs caused by previous atmospheric nuclear weapons tests fallout and the Chernobyl accident have been observed in Finnmark, Northern Norway. Due to the large consumption of potentially contaminated reindeer meat, whole body measurements of 137Cs levels in reindeer herders have been performed since 1965.
1: Cs-137 trend in marine sediments from East and West Greenland - to be compared with As data 2: Cs-137 in Greenland reindeer from areas with and without lichen
1) To perform simulation scenarios for the 21st century, including global warming scenarios, of potential radioactive spreading from sources in the Russian Arctic coastal zone and its impact on Barents, Greenland and Norwegian Seas and the Arctic Ocean; 2) To update the environmental and pollution data base of the Arctic Monitoring and Assessment Program (AMAP); 3) To assess, select and define the most probable simulation scenarios for accidental releases of radionuclides; 4) To implement a Generic Model System (GMS) consisting of several nested models designed to simulate radionuclides transport through rivers, in the Kara sea and in the Arctic ocean / North Atlantic; 5) To carry out simulation studies for the selected "release" scenarios of radionuclides, using various atmospheric forcing scenarios; 6) Assess the impact on potential radioactive spreading from sources as input to risk management.
To investigate the impacts of Russia's military and civilian nuclear activities in the Kola Bay and adjacent areas of the northwest Arctic coast of Russia.
(1) Collate information relating to the environmental transfer and fate of selected radionuclides through aquatic and terrestrial ecosystems in the Arctic. (2) Identify reference Arctic biota that can be used to evaluate potential dose rates to biota in different terrestrial, freshwater and marine environments (3) Model the uptake of a suite of radionuclides, both natural and anthropogenic to reference Arctic biota (4) Develop a reference set of dose models for reference Arctic biota (5) Compile data on dose-effects relationships and assessments of potential radiological consequences for reference Arctic biota (6) Integrate assessments of environmental impact from radionuclides with those for other contaminants.
The project aims to carry out an environmental assessment of the marine environment close to the three main settlements in the Isfjorden complex; Barentsburg, Longyearbyen and Pyramiden. The study comprises analyses of sediment geochemistry and soft-bottom benthic fauna. Attention is given to distinguishing atmospheric transport of contaminants from those arising from local sources.
It is suggested to analyse a variety of samples from Greenland and the Faroe Islands for radionuclides. The technetium pulse now under way from England will be surveyed in seawater, seaweed and shrimp, and time trends in concentrations of caesium-137, strontium-90 and plutonium will be monitored in selected components of marine, fresh water and terrestrial environments. As far as possible, the sampling programme is coordinated with other sampling programmes in Greenland and the Faroe Islands. It is suggested to re-investigate the weapons plutonium pollution in Bylot Sound off Pituffik on a 5-year basis i.e. year 2002 in the present AMAP programme
The benthic marine environment in Bylot Sound off the Thule Air Base was contaminated with ca. 1.4 TBq 239,240Pu (ca. 0.5 kg) in 1968. The site was revisited August 1997 aiming mainly at a new inventory estimate and at quantifying transfer to benthic biota.
