Translocation studies of 137Cs and 90Sr in bean plants (Phaseolus vulgaris): simulation of fallout

Foliar contamination of Phaseolus vulgaris with aerosols of 137Cs, 85Sr, 133Ba and 123mTe: influence of plant development stage upon contamination and rain

“…3). This is in agreement with previous results obtained by Vandecasteele et al (2001) and Macacini et al (2002) with various plant species and similar experimental conditions. Furthermore, when the interception factor is related to the yield (kg fresh matter per m 2 ), the results display similar trends as those obtained in close experimental conditions with lettuce by Rauret et al (1995) ( Table 2).…”

“…This particular trend was also recorded by Macacini et al (2002) for beans and by Vandecasteele et al (2001) for wheat. Flowering corresponds to the fastest period of growth for plants, which correlates with an increased demand for the various nutrients.…”

“…They showed that most of the calculated interception parameters for grass stand within the range 2-3 m 2 kg À1 . Few references deal with the interception of radionuclides by other plants species, especially vegetables, but these suggest that interception increases with an older development stage and increasing foliage surface (Rauret et al, 1995;Vandecasteele et al, 2001;Macacini et al, 2002).…”

A dynamic model for assessing radiological consequences of routine releases in the Loire river: parameterisation and uncertainty/sensitivity analysis

“…These values were confirmed by Pro¨hl et al (1990) for Cs in barley and wheat ðt max tr from 35 to 40 days Á , but higher values were observed for potatoes (80 days). Experiments performed by Aarkrog (1969Aarkrog ( , 1975 with other radionuclides (Co, Sb, Ru, Sr, Cs, Mn, Fe) and by Macacini et al (2002) with Cs showed that t max tr is generally in the period (30e50 days) before harvest, except for Sr, Ru and in some cases Ce (less than 10 days). Such experimental data were used to propose uniform PDFs for the parameter t max tr .…”

Transfer and translocation of241Am,239Pu,137Cs and85Sr after partial foliar contamination of bean plants

“…Foliar transfer parameters of classical fission products, Cs and Sr, had been intensively studied in the past and numerous values of foliar transfer descriptive parameters had fed radioecological and crisis management codes, such as the ASTRAL code of IRSN [3]. Thus, Cs, is a mobile element in plants, its behaviour being like that of K and Sr is non-mobile, behaving like Ca [4,5,6,7,8,9]. However, transuranium elements had not received the same attention.…”
