After the Fukushima Daiichi Nuclear Power Plant accident in 2011, Iitate village was placed under an evacuation order because the level of radioactive materials drifting from the nuclear plant to the village were above a government-set level for allowing residents to live in the area. The evacuation advisory for most of the village was lifted on March 31, 2017. For displaced residents deciding whether or not to return to their homes, it is important to correctly understand and estimate the realistic individual external doses they will receive after returning to the village...

PURPOSE OF REVIEW: This article describes the debates in Japan regarding the 100 mSv threshold assumption and ethical issues related to it, and explores the background to distorted risk information and absence of risk communication in Japan. Then we seek proper risk communication based on scientific evidence. RECENT FINDINGS: On March 11, 2011 an accident occurred at the Fukushima Daiichi Nuclear Power Plant due to the Great East Japan Earthquake. Since then a number of misunderstandings have become common in Japan as a result of public statements by the Japanese and local governments that have no basis in medical science or are contradictory to medical science...

A considerable portion of agricultural land in central-east Japan has been contaminated by radioactive material, particularly radioactive Cs, due to the industrial accident at the Fukushima Daiichi nuclear power plant. Understanding the mechanism of absorption, translocation, and accumulation of Cs(+) in plants will greatly assist in developing approaches to help reduce the radioactive contamination of agricultural products. At present, however, little is known regarding the Cs(+) transporters in rice. A transporter-enriched yeast expression library was constructed and the library was screened for Cs(+) transporter genes...

The east Japan earthquake that occurred on March 11, 2011 was a big natural disaster, comprising the large earthquake shock, tsunami, and Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. These disasters caused changes in the land use and land cover (LULC) in Japan's Tohoku district. While the LULC map created before the disaster is available, as yet there is no precise LULC map of the district after the disaster. In this study, we created a precise LULC map for the years 2013-2015 post-disaster with 30-m spatial resolution using the Landsat-8 with the Operational Land Imager (OLI) to evaluate the changes in LULC induced by the disaster...

Most studies of the properties of airborne radionuclides emitted from the Fukushima Daiichi Nuclear Power Plant have focused on the relatively early stages of the accident, and little is known about the characteristics of radiocesium in the long-term. In this study, we analyzed activity size distributions of airborne radiocesium collected over 5 months in Tsukuba, Japan. Radiocesium in the accumulation mode size range (0.1-2 μm in aerodynamic diameter) was overwhelming in the early aerosol samples and decreased with time, while that associated with coarse aerosols remained airborne...

Nuclear fusion technology is expected to create new energy in the future. However, nuclear fusion requires a large amount of tritium as a fuel, leading to concern about the exposure of radiation workers to tritium beta radiation. Furthermore, countermeasures for tritium-polluted water produced in decommissioning of the reactor at Fukushima Daiichi Nuclear Power Station may potentially cause health problems in radiation workers. Although, internal exposure to tritium at a low dose/low dose rate can be assumed, biological effect of tritium exposure is not negligible, because tritiated water (HTO) intake to the body via the mouth/inhalation/skin would lead to homogeneous distribution throughout the whole body...

A thyroid ultrasound examination program has been conducted in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident to address concerns about the increased risk of thyroid cancer similar to those experienced by local residents after the 1986 Chernobyl accident. This is the second-largest thyroid cancer screening in younger age ever, following only that conducted after Chernobyl. As the natural history of thyroid cancer in younger populations is not well characterized, large-scale screening using thyroid ultrasound could result in overdiagnosis, even with careful planning, as has been experienced in South Korea...

The Great East Japan Earthquake occurred on March 11, 2011, and was followed by a nuclear accident at the Fukushima Daiichi Nuclear Power Plant. The government ordered a mandatory evacuation from the high radioactive concentration area in Fukushima. This evacuation may have forced many evacuees to change specific aspects of their lifestyles such as diet and physical activity, which in turn may lead to future incidence of lifestyle diseases such as cardiovascular diseases (CVDs). To address this concern, the association between the evacuation and changes in CVD risk factors before and after the disaster was examined in the Fukushima Health Management Survey...

After the Great East Japan Earthquake and the subsequent nuclear reactor accident, the outdoor activities of children greatly decreased. We investigated adverse effects on the exercise habits and mental health of children after the disaster. The target subjects were children aged 6 to 15 years living inside the government-designated evacuation zone as of March 11, 2011 (n = 29  585). The subjects' parents/guardians completed the Strengths and Difficulties Questionnaire (SDQ) and exercise habit data were obtained from the 2011 Fukushima Health Management Survey...

The disaster at the Fukushima Daiichi Nuclear Power Plant after the Great East Japan Earthquake on March 11, 2011, might have affected the mental health status of children. To assess the mental health status, we measured the Strengths and Difficulties Questionnaire (SDQ) in 15 274 children (aged 4-15 years). The proportions of those who scored above the cutoff (≥16) of SDQ, reflecting the clinical range of the mental health status, were 25.0% (aged 4-6 years), 22.0% (aged 7-12 years, and 16.3% (aged 13-15 years), which were higher than that in the usual state (9...
