Suspended particle-water interactions increase dissolved 137Cs activities in the nearshore seawater during typhoon Hagibis.

Environmental Science and Technology, 2020
Distributions of 137Cs in dissolved and particulate phases of the downstream of seven rivers and adjacent nearshore and offshore waters as far as ~60 km south of the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) were studied during the high-river-flow ...

Phytoextraction of 137Cs: The Effect of Soil 137Cs Concentration on 137Cs Uptake by Beta vulgaris

Acta Biotechnologica, 2002
The last phase for MAGNOX ELECTRIC plc's reactor decommissioning strategy is site clearance and delicencing. Phytoextraction of 137Cs may be able to assist in meeting this objective. Field trials using Beta vulgaris conducted at Bradwell Nuclear Power Station, Essex, UK, aimed to show whether phytoextraction might be a practical remediation technique ...

Reactive barriers for 137Cs retention

Journal of Contaminant Hydrology, 2001
137Cs was dispersed globally by cold war activities and, more recently, by the Chernobyl accident. Engineered extraction of 137Cs from soils and groundwaters is exceedingly difficult. Because the half-life of 137Cs is only 30.2 years, remediation might be more effective (and less costly) if 137Cs bioavailability could be demonstrably limited for even a

A Biokinetic Model for 137Cs

Health Physics, 1997
An improved biokinetic model for 137Cs in humans was developed based on an analysis of data obtained from individuals internally contaminated during an accident in Goiania, Brazil, and other data. Seventeen children (ten girls and seven boys 1-10 y old), ten adolescents (four females and six males), and thirty adults, (fifteen females and fifteen males

The Ratio of Plant 137cs to Exchangeable 137cs in Soil is a Crucial Factor in Explaining the Variation in 137cs Transferability from Soil to Plant

SSRN Electronic Journal, 2022
To mitigate radioactive cesium from soil to plant, increasing and maintaining the exchangeable potassium (ExK) level during growth is widely accepted after Tokyo Electric Company's Fukushima Dai-ichi Nuclear Plant accident in Japan. This is because the antagonistic relationship between soil solution K and 134Cs + 137Cs (RCs) concentrations changes the ...

Derivation of 137Cs deposition density from measurements of 137Cs inventories in undisturbed soils

Journal of Environmental Radioactivity, 2002
The 137Cs inventories in undisturbed soils were measured for 292 locations across the territory of Vietnam. The logarithmic inventory values were regressed against characteristics of sampling sites, such as geographical coordinates, annual rainfall and physico-chemical parameters of soil.

Radiocarbon and 137Cs dating of wines

Journal of Environmental Radioactivity, 2020
Wine dating methods based on anthropogenic 14C and 137Cs, as well as on the cosmogenic 14C were studied with the aim to improve the accuracy and precision of the dating results. While the 14C dating method has proved to be useful for dating young and old wines, the 137Cs has been effective for dating of wines originating around the 137Cs bomb-peak ...

Highly Selective Radioactive 137Cs+ Capture in an Open-Framework Oxysulfide Based on Supertetrahedral Cluster

Chemistry of Materials, 2019
Removal of 137Cs+, one of the most hazardous radionuclides, from nuclear waste, is a challenging task because it requires simultaneously high capacity and high selectivity.

Vertical profile of 137Cs in soil

Applied Radiation and Isotopes, 2004
In this paper, a vertical distribution of 137Cs in undisturbed soil was investigated experimentally and theoretically. Soil samples were taken from the surroundings of the city of Kragujevac in central Serbia during spring-summer of 2001. The sampling locations were chosen in such a way that the influence of soil characteristics on depth distribution ...
