Decadal stability of radiocesium inventories and soil to tree transfer in forests affected by the Fukushima nuclear accident [PDF]

Scientific Reports
Understanding the long-term dynamics of radiocesium (137Cs) in forests contaminated by the Fukushima nuclear accident requires determining when these dynamics reach a quasi-equilibrium state, in which the flux of 137Cs between soil and trees becomes ...

Migration mechanisms of 90Sr and 137Cs on terraces

Journal of Environmental Radioactivity, 2023
In order to investigate the impact of environmental conditions on the distribution and migration of 90Sr in the Longji terrace environment, the activity concentrations of 90Sr and 137Cs were determined. The activity concentration ranges of 90Sr and 137Cs in surface soil were 0.15-1.04 Bq/kg and 2.16-6.94 Bq/kg, respectively.

Sexual dimorphism in 137Cs accumulation after chronic low dose exposure in mice [PDF]

Scientific Reports
The presence of Cesium-137 (137Cs) in the environment after nuclear accidents at Chernobyl and Fukushima Daiichi raises many health issues for the surrounding populations chronically exposed through the food chain.

Contribution of 137Cs-enriched particles to radiocesium concentrations in seafloor sediment: Reconnaissance experiment. [PDF]

PLoS ONE, 2018
Autoradiography was used to detect 137Cs-enriched particles in sediment samples. The contributions of 137Cs-enriched particles to 137Cs concentrations in sediment samples ranged from 9% to 64%.

Explaining the variation in 137Cs aggregated transfer factor for wild edible plants as a case study on Koshiabura (Eleutherococcus sciadophylloides) buds

Scientific Reports, 2023
The aggregated transfer factor (Tag) is commonly used to represent the actual transfer of radiocesium from soil to wild edible plants, but the values have shown substantial variation since the Fukushima nuclear accident.

Seasonal variation of Cesium-137 concentration in Asian black bear (Ursus thibetanus) and wild boar (Sus scrofa) in Fukushima Prefecture, Japan. [PDF]

PLoS ONE, 2018
To elucidate and reduce the risk of radionuclide contamination in wildlife caused by the Tokyo Electric Power Company Fukushima Dai-ichi Nuclear Power Station accident, it is important to understand radionuclide variations in the wild animal population ...

137Cs inventories in soil in the Qaidam Basin, Tibetan Plateau

Frontiers in Environmental Science, 2023
This paper presents measurements of cesium-137 (137Cs) in the Qaidam Basin during 2019 with 39 soil samples across the landscape. The aim here is to use the results of 137Cs inventories for the Qaidam Basin to subsequently estimate soil wind erosion. The

Effects of forest litter on dissolved 137Cs concentrations in a highly contaminated mountain river in Fukushima

Journal of Hydrology: Regional Studies, 2022
Study region: The upper, forested reaches of the Ota River, 24.4 km northwest of the Fukushima Daiichi nuclear power plant, was studied. Study focus: There is concern about the effects of dissolved radiocesium (137Cs) released from forest litter on long ...

Studies of 137Cs transfer in soil‐fern system

Journal of Environmental Engineering and Landscape Management, 2005
Fern accumulates radionuclides in abundance, including 137Cs. Tranfer of 137Cs and 40K in plants which have different root systems (fern or grass), or have no roots at all (moss) was compared.
