摘要
From a questionnaire on radioecological topics circulated in the framework of the IUR/EURADOS/EULEP Concerted Action supported by the EC it was concluded that the effect of soil fauna on the redistribution of radionuclides in soils has never been given sufficient attention. The limited data in existence suggest that faunal effects on displacement of radionuclides may be dominant over physicochemical migration. On the basis of a given dataset, an earthworm model is presented which shows that the activity decrease in the top soil layer due to bioturbation may compete with fast physicochemical migration at rates of 1 to 10 cm.y(-1). The model represents a suggestion of how to treat faunal actions and what kind of data are necessary to operate such models.
