Carbon, cesium and iodine isotopes in Japanese cedar leaves from Iwaki, Fukushima
Japanese cedar leaves from Iwaki, Fukushima were analyzed for carbon, cesium and iodine isotopic compositions before and after the 2011 nuclear accident. The Δ14C values reflect ambient atmospheric 14C concentrations during the year the leaves were sampled/defoliated, and also previous year(s). The elevated 129I and 134,137Cs concentrations are attributed to direct exposure to the radioactive f...
متن کاملRadiocaesium partitioning in Japanese cedar forests following the “early” phase of Fukushima fallout redistribution
Our study focused on radiocaesium (137Cs) partitioning in forests, three vegetation periods after the Fukushima Daiichi nuclear power plant accident. 137Cs distribution in forest components (organic and mineral soil layers as well as tree compartments: stem, bark, needles, branches and roots) was measured for two Japanese cedar stand ages (17 and 33 years old). The results showed that around 85...
متن کاملVertical profiles of Iodine-131 and Cesium-137 in soils in Fukushima Prefecture related to the Fukushima Daiichi Nuclear Power Station Accident
Soil core samples were taken on April 13, 2011 at three sites in Fukushima prefecture: Hiwada in Koriyama-city (Site 1; N 37°28′32′′, E 140°23′17′′; two cores were obtained in Site 1), Yabuki in Nishi-Shirakawa-county (Site 2; N 37°11′59′′, E 140°20′37′′), and Iizaka in Fukushimacity (Site 3; N 37°48′50′′, E 140°26′34′′). The distances of the three sites from the Fukushima Daiichi Nuclear Power...
متن کاملInternal Radiation Exposure Dose in Iwaki City, Fukushima Prefecture after the Accident at Fukushima Dai-ichi Nuclear Power Plant
As a result of the accident at the Fukushima Daiichi Nuclear Power Plant (FNPP) on 11 March 2011, a huge amount of radionuclides, including radiocesium, was released and spread over a wide area of eastern Japan. Although three years have passed since the accident, residents around the FNPP are anxious about internal radiation exposure due to radiocesium. In this study, we screened internal radi...
متن کاملRadioactive iodine and radioactive cesium: two important radio-hazard elements in post nuclear power plant crisis
The present nuclear leakage crisis from Japan is a topic to be discussed in present public health. In radiology, the leaked radioactive elements are considered hazard. Here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. Based on previous similar nuclear crisis in Russia, it ...
