“…Transfer factor calculation of a radionuclide for plants After mathematical simplification, transfer factor has as a unit kilogram of dry soil per kilogram of dry matter. It represents the dry soil mass with total activity corresponds to the activity in a unit mass of plant dry matter developed in that soil (Harada et al, 2014).…”

Stable cesium can be considered as the best element for desorption of soil radio-cesium. It is considered an element that slightly absorbed by plants, so that the application of high doses to the soil could increase the absorption of 137Cs, which is desired for the remediation of contaminated soils. There is shortage of knowledge on remediation of tropical and subtropical soils contaminated with 137Cs. The aim of this work was to evaluate the use of 133Cs for the remediation of Brazilian tropical and subtropical soils contaminated with 137Cs. In addition, we investigated the Cs uptake by bean plants (Phaseolus vulgaris L.) grown in Cs contaminated soil. The experiment was carried out in pots under greenhouse conditions. Seven soil types were used in the experiment (Oxisol, Udox, Psamment, Ochrept; Aquoll; Udox and Udult), which received the application of four doses of 133Cs (0, 5, 10 and 20 mg/pot in a completely randomized design arranged in a factorial scheme (7 soil types x 4 doses of 133Cs) with three replicates. An increase in transfer factor values of 137Cs was observed for both shoot growth and grains, as well as in percentage of total activity of 137Cs removed from the soil regarding to addition of stable cesium levels in all soils. The results showed that psamment soil presented higher specific activity of 137Cs in the soil and grains, as well as for the transfer coefficient from soil to shoot growth and grains. The application of stable cesium chloride to soil did not cause any effects on dry matter production of shoot growth and grains. The addition of 133Cs increased the transfer from soil 137Cs to the plant regardless of soil type, proving the efficiency of this practice for the remediation of soils contaminated with radioactive Cs. In addition, the plants of common bean were efficient for use in phytoremediation.

“…To the extent of our knowledge, there are no studies describing the variation in Cs concentration before and after composting. Some previous research has assessed the transfer of radioactive Cs from soil to crops following soil fertilization with contaminated organic materials [26]. Alexakhin (1993) [27] also reported that agricultural practices could effectively mitigate the radiological consequences of the Chernobyl accident in pasture grasslands.…”

“…However, amendment with raw materials resulted in significantly high soil Cs concentrations because of their high contamination with radioactive Cs. Harada et al (2014) [26] showed that radioactive Cs concentration significantly increases after soil amendment with contaminated cattle farmyard manure. Thus, adding sub-materials, such as rice bran and wheat meal, emerged as an effective strategy to control soil radioactive Cs concentration following the FDNPP accident.…”

“…The reduction in plant biomass in soils amended with raw materials was mainly due to low nutrient availability in these initial materials and the low concentration of decomposed products. Harada et al (2014) [26] demonstrated that the effects of using contaminated farm yard manure on the concentration of radioactive Cs found in crops depend not only on the contamination level, but also on factors, such as soil exchangeable K 2 O content. Furthermore, Hoshino et al (2015) [52] reported that the ecological behavior of radioactive Cs is influenced by the amount of clay minerals present in the soil.…”

Nutrient Status in Composts and Changes in Radioactive Cesium Following the Fukushima Daiichi Nuclear Power Plant Accident

Abstract:Following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, the forests in the Fukushima area were highly contaminated with radiocesium ( 137 Cs and 134 Cs). Therefore, there is a need to develop strategies for remediation of the contaminated forests. We assessed changes in radioactive cesium ( 134 Cs and 137 Cs) contamination and nutrient status in composts derived from wood chip, bamboo leaf and bamboo powder using rice bran and wheat meal as sub-materials. Changes in soil properties and Komatsuna (Brassica rapa var. perviridis) growth were also investigated due the application of composts and initial materials at 0, 2.5, 5 and 10 kg·m −2 input levels. Mixing of sub-materials significantly reduced the concentration of radioactive Cs and improved compost quality. The effectiveness of three composts on soil quality improvement varied depending on their types and rates of applications. Amendments of bamboo leaf composts at 10 kg·m −2 resulted in the significantly highest soil inorganic N, available P and exchangeable K contents. Amendments of final composts also enhanced Komatsuna growth. Furthermore, radioactive Cs contaminations of the Komatsuna plants grown in these composts were below 0.1 Bq·kg −1 . This study may help to remediate the forests contaminated with radiocesium in the Fukushima area while improving the soil organic matter content to enhance soil sustainability.

“…In field research before the accident, continuous FYM application by local farmers was able to maintain adequate levels of exchangeable K 2 O in their forage fields (Hatanaka et al 2004). Recently, Harada et al (2014) reported that application of FYM that was highly contaminated by radioactive Cs from the 2011 accident increased the soil radioactive Cs concentration, but not the TF. Therefore, the conventional nutrient management practiced by farmers-that is, continuous FYM application to keep adequate nutrient levels in soil-is one reason that the radioactive Cs concentrations in annual forage crops have been much lower than the provisional tolerance level after the Fukushima Daiichi Nuclear Power Station accident.…”

Abstract. These results suggest that continuous FYM application can maintain soil nutrients including K 2 O and thereby control radioactive Cs transfer from the soil. FYM application rate of 30 Mg ha −1 is within the levels recommended by the prefectural governments around Fukushima Prefecture for crop production before the accident. These levels are sufficient to decrease the radioactive Cs concentrations for corn. However, unlike corn, differences in soil chemical properties by FYM application did not affect 137 Cs concentrations in Italian ryegrass in this study, although low exchangeable K 2 O seemed to increase concentrations of stable 133 Cs. Further experiments should be conducted to understand the observed differences between corn and Italian ryegrass.
