Radioactivity TDC

The AMAP Radioactivity Thematic Data Centre holds radioactivity sources, levels and trends data for monitoring and assessment. The database is hosted by the Norwegian Radiation Protection Authority (NRPA), Oslo, Norway.

AMAP Thematic Data Centres compile data from relevant monitoring and research activities and make them available under strict conditions that protect the rights of data originators. AMAP TDCs are located at established centres with appropriate expertise and facilities for conducting the types of international data handling required. For more information, please visit the main AMAP website.

Below are projects that have specified Radioactivity TDC as one of the data repositories for the AMAP Project Directory. To see the full list of AMAP Thematic Data Centres, see the AMAP TDC list.

1. Monitoring of natural products in Finnish Lapland

The project monitors the artificial radioactivities in natural products in Finnish Lapland. The work mainly started after Chernobyl accident.

2. Plants obtained from permanent study plots as bioindicators for radioactive fallout

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.

3. Lichens obtained from permanent study plots as bioindicators for radioactive fallout

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.

4. Whole body measurements on reindeer herders in Finnmark, Norway

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.

5. Simulation Scenarios for Potential Radioactive Spreading in the 21st century from Rivers and External sources in the Russian Arctic Coastal Zone (RADARC)

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.

7. Environmental Protection from Ionising Contaminants in the Arctic (EPIC)

(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.

8. Environmental assessment of the Isfjorden complex, Svalbard

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.
