Abstract: The impact of the Fukushima nuclear accident in north–western Greece was assessed through an environmental monitoring programme activated by the Nuclear Physics Laboratory of the University of Ioannina. Measurements of 131I were carried out in atmospheric particulate, ovine milk and grass samples. In daily aerosol samplings, radioiodine was first detected on March 25–26, 2011 and reached maximum levels, up to 294 μBq m−3, between April 2 and April 4, 2011. In ovine milk samples, 131I concentrations ranged from 2.0 to 2.7 Bq L−1 between April 2 and April 6, 2011, while an average activity of 2.7 Bq kg−1 was measured in grass samples on April 4, 2011. The 134,137Cs isotopes were below detection limits in all samples and could only be determined in the air, by analysis of multiple daily filters. A maximum average activity concentration of 137Cs amounting to 24 μBq m−3 was measured during the period from April 5 to April 9, 2011, with the 134Cs/137Cs activity ratio being close to unity. Activity concentrations were consistent with measurements conducted in other parts of the country and were well below those reported in May 1986 after the Chernobyl accident. The committed effective dose to the whole body and to the thyroid gland from inhalation of 131I was estimated for the adult and infant population and was found to be of no concern for the public health.

Keywords: Prypiat,Ukraine, Fukushima, evacuees
Abstract: This research note is a memorandum for our interviews with those who lived in Prypiat city near the Chernobyl Nuclear Power Plant. The inhabitants in Prypiat had to be evacuated to other places due to the nuclear accidents in April, 1986. We conducted the interviews with them in order to examine one of several aspects of the socioeconomic and psychological sufferings they endured. The results of our survey show that there are some remarkable damages such as loss of property and home; disintegration of labor ability, places of education and community.

Abstract: A radioactivity survey program was launched in 1983 to determine the background levels of artificial radionuclides, such as 90Sr and 137Cs in the marine environment off commercial nuclear power stations. In this paper, we report on the long-term temporal changes of 90Sr and 137Cs in seawater, bottom sediment and marine organism samples. Both 90Sr and 137Cs have been detected since the beginning of the program in the seawater samples.

Abstract: We tried the decontamination of surface soils for three types of agricultural land at Nagadoro district of Iitate-mura (village) in Fukushima Prefecture, which is highly contaminated by deposits of radionuclides from the plume released from the Fukushima Daiichi nuclear power plant. The decontamination method consisted of the peeling of surface soils solidified using a polyion complex, which was formed from a salt solution of polycations and polyanions. Two types of polyion complex solution were applied to an upland field in a plastic greenhouse, a pasture, and a paddy field. The decontamination efficiency of the surface soils reached 90%, and dust release was effectively suppressed during the removal of surface soils.

Title: Unclaimed Fukushima psychological and neuropsychiatric lessons of Chernobyl

Abstract: The Japanese earthquake March 11, 2011 and subsequent tsunami and series of accidents at nuclear power plants were an exceptional challenge to the Japanese technology and the mentality of the nation. Prior to Fukushima, a level 7 event (the maximum classification) was earned only by the Chernobyl disaster. Was the Chernobyl and international experience counted and used regarding the mental health of victims in case of Fukushima?

Abstract: The degree of contamination with radioactive cesium (134Cs and 137Cs) in the human placenta after the accident at Fukushima nuclear power plant (FNP), which occurred on 11 March 2011, has not been assessed. Material and Methods:134Cs and 137Cs contents were determined in 10 placentas from 10 women who gave birth to term singleton infants during the period between October 2011 and August 2012 using high-purity germanium detectors for gamma ray spectrometry. Five women resided within 50 km of FNP (neighbor group) and gave birth by the end of February 2012, while the other five women resided within 210–290 km of FNP (distant group) and gave birth in July and August 2012.

Keywords: PTSD, cerebrovascular pathology, hippocampus, depression
Abstract: BACKGROUND: Whether posttraumatic stress disorder (PTSD) following radiation emergency has psychopathological, neurocognitive, and neurophysiological peculiarities is at issue.
OBJECTIVE: The goal was to explore the features and cerebral basis of “radiation” PTSD in the survivors of the Chernobyl accident. Subjects and Methods The cross-sectional study included 241 people, 219 of whom have been diagnosed with PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) criteria, among them 115 clean-up workers of the Chernobyl accident (34 with acute radiation sickness), 76 evacuees from the Chernobyl exclusion zone, 28 veterans of the war in Afghanistan, and 22 healthy unexposed individuals. Psychometric examinations, neurocognitive assessments, computerized electroencephalography, and cerebral vascular Doppler were used.
RESULTS: “Radiation” PTSD includes “flashforward” phenomena and anticipating stress (projection of fear and danger to the future); somatoform disorders (depression, trait and state anxiety); and neurocognitive deficit (impaired memory and attention, auditory-verbal memory and learning, proactive and retroactive interference, cerebellar and stem symptoms, intellectual changes). The intima-media component, thickness of common carotid arteries, and common and left internal carotid arteries stenosis rates are increased in the liquidators. Changes of bioelectrical brain activity as a decrease of beta- and theta-power, together with an increase of alpha-power, were found in the Chernobyl accident survivors with PTSD.
CONCLUSIONS: PTSD following radiation emergency is characterized by comorbidity of psychopathology, neurocognitive deficit, and cerebrovascular pathology with increased risk of cerebral atherosclerosis and stroke. The cerebral basis of this PTSD is proposed to be an abnormal communication between the pyramidal cells of the neocortex and the hippocampus, and deep brain structures. It is recommended that a system of emergency and long-term psychological and psychiatric care be organized for the survivors in Fukushima Daichi, Japan.

Title: Preliminary dose estimation from the nuclear accident after the 2011 Great East Japan Earthquake and Tsunami
Author: WHO
Reference: 2012
Keywords: World Health Organization (WHO), Fukushima
Abstract: The earthquake and tsunami in Japan on 11 March 2011 led to releases of radioactive material into the environment from the Fukushima Daiichi nuclear site. This report describes a preliminary estimate of radiation doses to the public resulting from this accident. These doses are assessed for different age groups in locations around the world, using assumptions described in the report.
The dose assessment forms one part of the overall health risk assessment being carried out by WHO of the global impact of the accident at the Fukushima Daiichi nuclear power plant. The health risk assessment is the subject of a separate WHO report published in February 2013.
