摘要：

The Cs-137 activity concentrations in moose and their principal fodder plants as well as the botanical composition of the rumen content in moose were studied in three areas of the county of Vasternorrland in Sweden. The mean Cs-137 activity concentration in moose muscle samples from the three areas with a ground deposition from 20 to 60 kBq m-2 varied between 540 and 915 Bq kg-1. During the period July to October, three plant species - fireweed, birch and bilberry - constitute more than 70% of the rumen content. Estimation of the daily Cs-137 intake was performed based on the botanical analysis of rumen content and the Cs-137 activity concentrations found in samples of fodder plants. A mean F(f) of 0.19 day kg-1 was calculated. A mean aggregated transfer factor of 0.016 m2 kg-1 was found for the three areas.
