“…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). The ratio was higher for young plants (interception=yield ¼ 1 1:2) than for mature plants (0.3), as if interception was more effective at earlier stages.…”

“…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).…”

Experiments on a simulated terrestrial agricultural ecosystem were carried out using the pot culture approach. The most representative plants in local vegetable gardens were selected to investigate the root uptake of (110m)Ag. The results show that carrot, kale and flowering cabbage have the largest transfer factor values among the vegetables. Flowering cabbage, as the most popular leafy vegetable in Hong Kong and the South China area, can be used as a biomonitor for radioisotope contamination in vegetables. Soil column and adsorption tests were also carried out to study the leaching ability of the silver isotope in soil and (110m)Ag was mainly adsorbed in the top 1 cm of soil regardless of the pH value. Experiments on a simulated aquatic ecosystem for freshwater fish and marine organisms were carried out in glass aquaria. The freshwater fish Cyprinus carpio, the marine fish Cuvier and some local abundant seashore molluscs were selected to investigate the kinetic metabolism of (110m)Ag in the compartmental system. The results show that molluscs absorb (110m)Ag much more than fish. Clibanarius infraspinatus has the largest concentration factor among the marine organisms selected. Fish liver, although representing a minor portion of the total body mass, shows the highest (110m)Ag concentration factor, whereas muscle, although representing a major portion of the total body mass, is characterized by an absence of (110m)Ag.

Interception, loss and translocation of⁸⁵Sr,¹⁰³Ru and¹³⁴Cs in the rice plants sprayed with a mixed Rl solution

Interception, loss and translocation of * s Sr, l0J Ru and 1M Cs in rice plants were investigated through a greenhouse experiment in which the whole aboveground plant parts were exposed to radioactive spray at 6 different growth stages. Showing little difference among radionuclides, the interception factor tended to increase as the plant grew to maturity. The highest observed factor was 0.94. The fractions of the intercepted activity that remained in rice plants at harvest were 0.19~0.42 for BS Sr, 0.23-0.62 for IM Ru and 0.11-0.69 for lM Cs, depending on application times. The translocation factors for hulled seeds were in the range of 5.8xl0 4~3 .2xl0 ! for "Sr, 1.6x10^7.6x10 s for 103 Ru and 3.2xl0" 3~2 .0x10'' for IM Cs indicating the highest mobility of 1M Cs. The greatest translocation factor of every radionuclide came when plants were contaminated at the active seed growth stage. It was indicated that weathering loss and translocation would not greatly depend on the rain frequency if it differs by a factor of less than 2. Based on the experimental results, the concentrations of S5 Sr, w Sr, 103 Ru, l06 Ru, iW Cs and ,37 Cs in hulled rice seeds at harvest were estimated for their deposition at different growth stages
