“…The Tokyo Electric Power Company (FNPP owner and operator, TEPCO) estimated that 500 PBq of radioactive noble gases, 500 PBq of iodine-131 ( 131 I), 10 PBq of cesium-134 ( 134 Cs) and 10 PBq of 137 Cs were released from FNPP to the atmosphere between March 12 and 31, 2011 [2] and that atmospheric fallout and direct leakage from the reactors released an additional 11 PBq of 131 I, 3.5 PBq of 134 Cs and 3.6 PBq of 137 Cs into the marine environment between March 26 and September 30, 2011 [3]. Meanwhile, total deposition of 137 Cs from the atmosphere onto the ocean surface is estimated to have been 5-15 PBq [4][5][6][7][8]. Estimates of direct 137 Cs leakage from FNPP into the sea range from 3 to 6 PBq [5][6][7][8][9][10][11][12][13].…”

In June 2014, May and June 2015, and June 2016, we conducted quantitative quadrat surveys of sessile invertebrates at seven intertidal sites in Ibaraki, Fukushima, and Miyagi Prefectures, including the sites near Fukushima Daiichi Nuclear Power Plant (FNPP), to check whether species richness, population densities, and biomass had recovered from declines after the 2011 Tohoku earthquake, tsunami and nuclear disaster. Additionally, in April, July, August and September from 2012 to 2017, we monitored the population density and spawning behavior of rock shells (Thais clavigera) in the field near FNPP. Increases in species richness and population densities in the intertidal zone near FNPP were not found until at least 4-5 years had passed after the FNPP accident. Densities of and reproductive performance by T. clavigera populations near FNPP in 2017 remained below levels before the accident. Although invertebrate larval recruitment from remote areas to the intertidal zone near FNPP could have been expected, this was not clearly observed until 2016 at the earliest. Thus, it is possible that environmental factors inhibited invertebrate reproduction, recruitment or both in the intertidal zone near FNPP at least for 5 years.

“…Despite this generally low radiation exposure, which was clearly below the threshold of acute radiation disease, about 90,000 people were evacuated as a preventive safety action. This measure reduced the levels of possible exposure but also resulted in a number of evacuation-related deaths due to stress and/or lack of medical and social welfare facilities 2 . Hence, a rapid and accurate biodosimetry method would reduce the uncertainty about received doses and may mitigate psychological and health problems related to additional stress among the individuals who may or may have not been exposed to radiation (the so-called “worried wells”) 3 4 .…”

Accurate assessment of the individual exposure dose based on easily accessible samples (e.g. blood) immediately following a radiological accident is crucial. We aimed at developing a robust transcription-based signature for biodosimetry from human peripheral blood mononuclear cells irradiated with different doses of X-rays (0.1 and 1.0 Gy) at a dose rate of 0.26 Gy/min. Genome-wide radiation-induced changes in mRNA expression were evaluated at both gene and exon level. Using exon-specific qRT-PCR, we confirmed that several biomarker genes are alternatively spliced or transcribed after irradiation and that different exons of these genes exhibit significantly different levels of induction. Moreover, a significant number of radiation-responsive genes were found to be genomic neighbors. Using three different classification models we found that gene and exon signatures performed equally well on dose prediction, as long as more than 10 features are included. Together, our results highlight the necessity of evaluating gene expression at the level of single exons for radiation biodosimetry in particular and transcriptional biomarker research in general. This approach is especially advisable for practical gene expression-based biodosimetry, for which primer- or probe-based techniques would be the method of choice.

“…Owing to physical and biogeochemical processes in the ocean, artificial radionuclides in the ocean are redistributed from their initial entry points which depend on the various sources. The extent of radioactive contamination in the ocean due to atmospheric weapons tests, releases from nuclear fuel reprocessing plants, and accidental releases from nuclear power plants (i.e., the Chernobyl accident in 1986 and the Fukushima accident in 2011) is of global concern [ 1 – 3 ].…”

Long-range transport of radiocaesium derived from global fallout and the Fukushima accident in the Pacific Ocean since 1953 through 2017—Part I: Source term and surface transport

Long range transport of radiocaesium derived from local fallout occurred early 1950s, global fallout which occurred mainly late 1950s and early 1960s and the Fukushima accident occurred in 2011 were investigated and presented for ocean surface in the Pacific Ocean. HAM database and its update were used in this study to present whole history of radioccaesium transport in surface layer in the interested region. Since both the main local/global fallout regions and injection of radiocaesium by Fukushima accident occurred in the western North Pacific and constrain of surface current systems which governed surface transport processes were subtropical gyre and subarctic gyre, radiocaesium transport in surface water in the mid latitude was characterized as rapid eastward transport along Kuroshio and Kuroshio extension. Behaviors were similar and repeated for local/global fallout and Fukushima derived radiocaesium. A part of radiocaesium transported/deposited/injected in the mid latitude subducted into ocean interior and the radiocaesium activity concentrations were kept higher rather than those in surface water.Electronic supplementary materialThe online version of this article (10.1007/s10967-018-6244-z) contains supplementary material, which is available to authorized users.
