  abstract = {{I}n 1960 experiments were carried out on the transfer of {S}r-90 between soil, grapes and wine. {T}he experiments were conducted in {S}itu on a piece of land limited by two control strips. {T}he {S}r-90 migration over the last 40 years was studied by performing radiological and physico-chemical characterizations of the soil on eight 70 cm deep cores. {T}he vertical migration modeling of {S}r-90 required the definition of a triple layer conceptual model integrating the rainwater infiltration at constant flux as the only external factor of influence. {A}fterwards the importance of a detailed soil characterization for modeling was discussed and satisfactory simulation of the {S}r-90 vertical transport was obtained and showed a calculated migration rate of about 1.0 cm year(-1) in full agreement with the in situ measured values. {T}he discussion was regarding some of the key parameters such as granulometry, organic matter content (in the {V}an {G}enuchten parameter determination), {K}d and the efficient rainwater infiltration. {B}esides the experimental data, simplifying assumptions in modeling such as water-soil redistribution calculation and factual discontinuities in conceptual model were examined.},
