“…Therefore, radiocesium contamination by root uptake was likely negligible during the accident year, as was reported by Antonopoulos-Domis et al (1990) in relation to the Chernobyl accident. Carini and Bengtsson (2001), in their review of an interesting experiment conducted by Katana and colleagues, showed that 134 Cs migrated into mature apple fruits from the bark of a 2-year-old stem kept in contact with the cesium-134 ( 134 Cs) solution after 10 weeks. Investigation of radiocesium deposition in orchards and development of decontamination methods were started on April 11, 2011, by the Fruit Tree Research Center of Fukushima Agricultural Technology Center (FTRC).…”

Following the accident at the Tokyo Electric Power Company, Fukushima Daiichi Nuclear Power Plant (FDNPP), radiocesium ( 134 Cs + 137 Cs) concentrations in deciduous mature fruits were determined in orchards in the northern area of Fukushima Prefecture. At the time of the nuclear accident, most deciduous fruit trees were in the dormant stage prior to bud burst. To evaluate the relationship between radiocesium deposition in the soil and fruit contamination, radiocesium concentrations were measured from the 5-cm topsoil and from six fruit species across 17 orchards in 2011. The vertical distribution of radiocesium in the topsoil (0-30 cm in depth) and its spatial distribution in the 5-cm topsoil underlying the tree canopy of a peach, Prunus persica (L.) Batsh, orchard ("Akatsuki" cultivar) were also investigated. Significant correlations between the radiocesium concentration in the mature fruit and that in the 5-cm topsoil layer were observed for the 17 orchards as well as for the trees of the peach orchard. However, 93% of the 137 Cs found in the 30-cm soil core was retained within the top 3 cm of the soil in the peach orchard. Considering the profile of the root of this deciduous fruit tree, we assumed a negligible level of radiocesium uptake via the roots. However, the possibility of inward migration via the bark was undeniable, because some radiocesium adhered to the tree canopy before bud burst while depositing on the soil surface. Additionally, transfer factors for peach and grape, hybrid of Vitis labrusca L. and Vitis vinifera L., from young, uncontaminated trees cultivated with contaminated soil were lower than those previously reported.Key words: Fukushima Daiichi nuclear accident, inward migration via the bark, radiocesium in fruits, vertical distribution in orchard soil.

“…On the other hand, the 137 Cs concentration in fruits decreases by the dilution effect of assimilates transported into fruits in the ripening stage (Sato et al, 2015). In addition, the effects of bark washing on decreasing the Cs from leaves to fruits in the ripening stage (Carini and Bengtsson, 2001). In this regard, the decrease in 137 Cs concentration with days after full blossom in fruits in the washed trees was reasonable.…”

“…In addition, during winter, birch canopies were shown to intercept 20-25% of re-suspended radioactive particles (International Atomic Energy Agency, 2010a). Furthermore, Carini and Bengtsson (2001) introduced in their review an interesting experiment that was conducted by Katana et al (1988). It showed that 134 Cs migrated into mature apples from the bark of one two-year-old stem kept in contact with 134 Cs solution for 10 weeks.…”

This paper describes the approach taken to present the information on fruits in the IAEA report TRS No. 472, supported by the IAEA-TECDOC-1616, which describes the key transfer processes, concepts and conceptual models regarded as important for dose assessment, as well as relevant parameters for modelling radionuclide transfer in fruits. Information relate to fruit plants grown in agricultural ecosystems of temperate regions. The relative significance of each pathway after release of radionuclides depends upon the radionuclide, the kind of crop, the stage of plant development and the season at time of deposition. Fruit intended as a component of the human diet is borne by plants that are heterogeneous in habits, and morphological and physiological traits. Information on radionuclides in fruit systems has therefore been rationalised by characterising plants in three groups: woody trees, shrubs, and herbaceous plants. Parameter values have been collected from open literature, conference proceedings, institutional reports, books and international databases. Data on root uptake are reported as transfer factor values related to fresh weight, being consumption data for fruits usually given in fresh weight. *
