Mortensen | | Abstract: | This report describes the national systems for monitoring artificial radioactivity in the
five Nordic countries (Denmark, Finland, Iceland, Norway and Sweden), including
national similarities and differences regarding strategy and equipment. The backbone
of the national system for early warning is a network of automatic gamma monitoring
stations. It is complemented by manual stations and/or survey teams measuring in
predetermined points. Air filter stations are used for nuclide specific analyses of aerosols
and gaseous iodine. Fallout maps (especially for cesium-137) and isocurves (dose
equivalent rates) are produced based on data from airborne measurements, monitoring
stations, survey teams and environmental samples. All five countries have extensive
programs for checking food contamination. Whole body counting and organ measurements
are used to determine internal contamination. External contamination of
people, vehicles, goods etc. is checked with survey meters and other equipment at
checkpoints or as needed. Field measurements of various kinds complete the national
systems. Current routines and systems for exchange of radiation data between the
Nordic countries are summarized. A joint Nordic program for airborne measurements
is suggested. Possible future development and planned improvements are discussed. | | Publication date: | 01 Dec 1995 | | ISBN: | ISBN: 92-9120-679-2 | | Number of downloads: | 7385 | | Download: |  006.pdf |
