Abstract

The extent of radiocaesium retention in soil is important to quantify the risk of further foodchain contamination. The Radiocaesium Interception Potential (RIP) is an intrinsic soil parameter which can be used to categorize soils or minerals in terms of their capacity to selectively adsorb radiocaesium. In this study, we measured RIP for a large soil collection representative of major FAO soil reference groups and tested the possibility to predict the RIP on the basis of other easily measurable soil data. We compared RIP values with those obtained from separate chemical extraction experiments.Measured RIP values (1.8e13300 mmol kg1) were shown to include nearly all possible cases of agricultural soil contamination. Only Podzols, Andosols and Ferralsols were clearly characterized by a very low RIP (
