1. Monitoring of Cs-137 and Sr-90 in consumption milk

Monitoring of cesium-137 and strontium-90 in consumption milk is a sub-programme of a national monitoring program regarding environmental radiation in Sweden. The sub-programme has been ongoing since 1955. In the event of increased deposition of radionuclides, e.g. after a nuclear accident, transfer to cow milk is a quick process. The concentration in milk is therefore a good indicator of any changes of the levels of radionuclides in the area. Monitoring is performed at 5 dairies: Umeå, Sundsvall, Kallhäll, Jönköping and Malmö, where milk is sampled 4 times per year.

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. Continous monitoring of gammanuclides, strontium (beta) and tritium in deposition in Finnish Lapland

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.

4. Anthropogenic radionuclides in Greenland and the Faroe Islands

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
