The Huginn late-phase exercise was carried out by the NKS/BOK-1.4 project group in
the spring 2000. National teams from Denmark, Finland, Norway and Sweden took
part in the exercise. The objective of the exercise was to test the ability to calculate
the radiological and economical consequences of various agricultural
countermeasures following a nuclear accident. This report describes the findings of
the four national teams, including the approaches made by the teams, selection of
countermeasures and the results of the cost-benefit analyses that they performed. The
methods used and findings by the four teams have been compared and
recommendations issued based on the exercise results.
