Radiocesium transfer from soil is lower in tall fescue than orchardgrass under conditions of lower soil exchangeable potassium

Grassland Science, Volume 69, Issue 4, Page 253-260, October 2023., 2023
Abstract In Japan, additional potassium fertilization is used as a countermeasure for radiocesium‐contaminated grasslands in the Tohoku and North Kanto regions. A 2‐year pot experiment was conducted to assess the efficacy of using tall fescue (Festuca arundinacea Schreb.), a low‐cesium‐absorption grass species, to replace orchardgrass (Dactylis ...

Assessment of localized and resuspended 137Cs due to decontamination and demolition in the difficult‐to‐return zone of Tomioka town, Fukushima Prefecture

Integrated Environmental Assessment and Management, Volume 18, Issue 6, Page 1555-1563, November 2022., 2022
Abstract As the next step that occurred more than one decade after the accident at the Fukushima Dai‐ichi Nuclear Power Station (FDNPS), decontamination and demolition have been carried out in the Specified Reconstruction and Revitalization Base (SRRB) of the difficult‐to‐return zone around the FDNPS.

What do you mean, ‘megafire’?

Global Ecology and Biogeography, Volume 31, Issue 10, Page 1906-1922, October 2022., 2022
Abstract Background ‘Megafire’ is an emerging concept commonly used to describe fires that are extreme in terms of size, behaviour, and/or impacts, but the term’s meaning remains ambiguous. Approach We sought to resolve ambiguity surrounding the meaning of ‘megafire’ by conducting a structured review of the use and definition of the term in several ...

Seasonal concentrations of cesium-137 in rumen content, skeletal muscles and feces of caribou from the Porcupine herd: lichen ingestion rates and implications for human consumption

Rangifer, 1990
The Porcupine caribou herd was monitored for cesium-137 during 1987 to address human health concerns over potential meat contamination by radioactive fallout from the Chernobyl accident, and to determine lichen intake rates based on body burdens of ...

Horizontal distribution of Fukushima-derived radiocesium in zooplankton in the northwestern Pacific Ocean [PDF]

Biogeosciences, 2013
The magnitude of the 9.0 Tohoku earthquake and the ensuing tsunami on 11 March 2011, inflicted heavy damage on the Fukushima Dai-ichi nuclear power plant (FNPP1).

Watershed‐Geochemical Model to Simulate Dissolved and Particulate 137Cs Discharge From a Forested Catchment

Water Resources Research, Volume 58, Issue 8, August 2022., 2022
Abstract Measurements in forest catchments in Fukushima Prefecture indicate that cesium‐137 (137Cs) leaching from forest litter affects dissolved 137Cs levels in river water. Existing simulations have been unsuccessful in reproducing this phenomenon due to mechanistic limitations in the models connecting the forest ecosystem and the river system.

Reduction of Radiocesium in Internal- and Surface-Contaminated Komatsuna (Brassica rapa var. perviridis) during Washing and Processing

Journal of Food Protection, 2023
Radiocesium dynamics data during food processing are required for the realistic estimation of internal radiation content in food. Radiocesium contamination of leafy vegetables can occur externally due to the adhesion of fallout and/or resuspension from ...

Spread of Fukushima‐derived radiocesium over the coastal ocean in response to typhoon‐induced flooding in September 2011

Limnology and Oceanography, Volume 67, Issue 5, Page 1184-1193, May 2022., 2022
Abstract The Tohoku earthquake off the Pacific coast of Japan on 11 March 2011 and the resulting tsunami led to severe damage to the Fukushima Daiichi Nuclear Power Plant (FDNPP) in Japan. Therefore, a shipboard survey was conducted to elucidate spread processes of radioactive cesium over the coastal ocean in the Kuroshio–Oyashio transition zone (south
