TRANSFER OF RADIONUCLIDES TO FRUIT

A study has been carried out to determine soil-plant transfer factors relevant to fruit crops. ?he current default values for Cs-137, pu and Am used in the NRPB food-chain model FARMLAND were generally higher t han the TFs observed. Lower values would be more appropriate for gener al assessments. For the United Kingdom, the current approach in which TF values for apples are applied to all domestically produced fruit is considered reasonable. This study also indicates that the assumption that TFs for fruit are the same as those for green vegetables is reaso nable for Cs-137, Pu and Am, but, for Sr-90, data specific to apples w ould be preferable.
