Résumé

The soil-plant transfer of 137Cs and 90Sr was studied in a low turnover rate Mediterranean ecosystem. The available activities of the two radionuclides in the soil and their stable chemical analogues, K and Ca, respectively, evolve periodically over time due to the marked dry and wet seasons existing in this type of climate. This seriously restricts the validity of using constant transfer and discrimination coefficients
