“…Free ions of radiocesium are more readily adsorbed to soil matrices than those of radiostrontium (Choi et al, 2005a;Kim, 1985;Twining et al, 2004). If adsorbed ions were to be absorbed by plant roots, they should be desorbed back into soil solution.…”

“…A rapid downward migration of a radionuclide will result in its rapid loss from the effective root-zone soil. It is well known that the downward migration of radiostrontium is much more rapid than that of radiocesium (Choi et al, 1998(Choi et al, , 2005aCline and Rickard, 1972;Kliashtorin et al, 1994).…”

“…As a result, it is well established that stable ions chemically analogous to radionuclides can act as good suppressors through a competition for root uptake. The best examples are potassium (K) and calcium (Ca) against radiocesium and radiostrontium, respectively (Choi et al, 2005a;Ioannides et al, 2003;Nisbet et al, 1993;Romney et al, 1959;Shaw et al, 1992;Till and Meyer, 1983;Vidal et al, 2001;Wiklander, 1964;Zhu, 2001).…”

“…The mean activity concentration of 137 Cs in grass and soil was 0.31 and 2.39 Bq kg −1 and that of 40 K was 179 and 412 Bq kg −1 . The higher activity concentration of 137 Cs and 40 K could be due to the adhered soil particles to some extent and root uptake by paddy due to longer time span during the growing period of 3 to 4 months (Choi et al 2005;Hinton et al 1995).…”

The 137 Cs and 40 K activities and transfer factors from soil to vegetables, grass, and milk from villages located around Tarapur Atomic Power Station (TAPS) were determined using high-resolution gamma spectrometry. A total of 32 soil, 21 vegetable, 23 dry paddy grass, and 23 milk samples were collected from 23 different agricultural farms from various villages around TAPS to determine transfer factors for natural environment. The mean concentration values for 137 Cs and 40 K in soil, grass, and milk were 2.39± 0.86 Bq kg −1 , 0.31 ± 0.23 Bq kg −1 , and 12.4 ± 5.7 mBq L − 1 and 179±31 Bq kg − 1 , 412± 138 Bq kg −1 , and 37.6±9.3 Bq L −1 , respectively, for soil-grass-milk pathway. In the soil-vegetation pathway, the mean concentrations values for 137 Cs and 40 K were 2.15±1.04 Bq kg −1 , 16.5±7.5 mBq kg −1 , and 185±24, 89±50 Bq kg −1 , respectively. The evaluated mean transfer factors from soil-grass, grass-milk, and soil-vegetation for 137 Cs were 0.14, 0.0044, and 0.0073 and that of 40 K were 2.42, 0.0053, and 0.49, respectively. Only 15 out of total 44 milk and vegetable samples were detected positive for 137 Cs, indicating a very low level of bioavailability.

Abstract. This study focused on the radioecology of rice and explored how the French specificities of rice cultivation can be taken into account in risk assessment. The objective of the study was to characterize the radioecological sensitivity of rice with respect to an accidental release of radioactivity. We want to know if a uniform and specific deposit would involve the same contamination on representative paddy fields of Camargue. To model the transfer of the radionuclides in the rice caryopsis following an accidental atmospheric pollution, we used the classical modelling for the cereals which considers first the interception by the foliage (modelled by an interception ratio) then the translocation to the grain (modelled by a translocation factor). The values of the parameters (interception ratio, translocation factor and yield) were regionalized with the agronomical software ORIZA2000, developed by the IRRI (International Rice Research Institute). We partly calibrated ORIZA2000 for a French rice variety: Ariete, thanks to physiological data provided for International Cooperation Centre in Agronomical Research for Development (CIRAD). ORIZA2000 proposes a daily follow-up of the leaf area index which can be correlated with the interception ratio. Five simulations with various climates, irrigation managements, and technical uses have been inputted on ORIZA2000. The data inputted were extracted from the database AGROSYST from the French Institute for Agronomical Research (INRA) and from the CIRAD. We established two scenarios of contamination. The first one consisted in a single contamination of water. In this case, there is almost no difference between simulations. However, in each simulation (except for organic farming) it is relevant to notice that the fourth depletion of water leads to a significant variation of contamination. The second contamination scenario consisted in a double contamination of water and of air. In that case, technical practices are responsible of the highest source of variability of the grain contamination. The variability of the contamination is mainly due to the variability of the yield which has in the radioecological modelling a dilution effect. The rice produced by organic farming is more sensitive than the rice produced by conventional farming because of low yields.
