“…The Sr content of Thai rice was also lower than Spanish rice and Chinese rice. The levels of Cs and Sr in rice samples depend on the topography, soil properties and soil conditions [4,20].…”

“…In general, isotopes of the same element behave similarly in terms of their physical properties and chemical reactivity. Therefore soil to plant transfer factor of stable isotopes can serve as analogues of radioisotopes, e.g., stable Cs for Cs-137 and stable Sr for Sr-90 [4]. Because of very low concentration of radioactive materials in the environment of most countries in the world, the concentration of stable element related to long-lived radionuclides was studied.…”

Abstract. For long-term radiation dose assessment models, food ingestion is one of the major exposure pathways to human. In general, the stable isotopes can serve as analogues of radioisotopes. In this study, rice samples were collected from 30 paddy fields in Si Sa Ket, Yasothon and Roi Et in the northeast of Thailand in November 2014. The concentrations of stable cesium (Cs-133) and strontium (Sr-88) in polished rice were determined by inductively coupled plasma mass spectrometry (ICP-MS). The standard reference material of rice flour (NIST 1568a) with spiked Cs and Sr was used to validate the analytical method. The concentration of Cs in polished rice from Si Sa Ket, Yasothon and Roi Et was 0.158  0.167 mg kg -1 , 0.090  0.117 mg kg -1 and 0.054  0.031 mg kg -1 , respectively. The concentration of Sr in polished rice from Si Sa Ket, Yasothon and Roi Et was 0.351  0.108 mg kg -1 , 0.364  0.215 mg kg -1 and 0.287  0.102 mg kg -1 , respectively. Comparison of the results with Japanese data before the Fukushima Di-ichi nuclear power plant accident showed that the concentrations of both Cs and Sr for Thai rice were higher than those for Japanese rice.

“…Cultivation under flooded conditions deeply modifies the chemical characteristics of the soil-plant system and has consequently important effects on plant uptake of radionuclides from soil. Based on the review of more than 30 original sources, robust information has been made available for the assessment of the transfer of some radionuclides to rice (Sr, Cs, Mn, Co, Zn, Tc, I, Ra, Th, U and some stable elements) (Uchida et al, 2009).…”

“…Recently there has been considerable interest in the international community in a range of in-situ and ex-situ remediation technologies for radioactively contaminated soil and groundwater, including a low expense and large scale application of phytoremediation [4,6]. While these technologies have been applied in a range of environments, their application in clay and silt-rich soils may have raised the problem, due largely to the low hydraulic conductivities of these soils.…”

Abstract. Agar matrix was artificially contaminated with caesium and subjected to rapid assessment of electrokinetic treatment on the basis of the 2D electrode configuration. The effect of caesium concentration on the process was investigated using different electrode configuration (i.e. rectangular, hexagonal and triangular). During treatment the in situ pH distribution, the current flow, and the potential distribution were monitored. At the end of the treatment, the caesium concentration distribution was measured. The results of these experiments showed that for caesium contamination, pH control is essential in order to create a suitable environment throughout the agar matrix to enable contaminant removal. It was found that the type of electrode configuration used to control the pH affected the rate of caesium accumulation. All of the electrode configurations tested was effective, but the highest caesium extraction was achieved when the hexagonal pattern was used to control the pH. After 72 h of treatment at 50 mA, the concentration of caesium decreased gradually from the second and first layer of agar matrix throughout the cell, suggesting that most of the caesium was concentrated on the cathode part.
