Measurement of Fukushima-related radioactive contamination in aquatic species.
The Great East Japan (Tohoku) Earthquake and consequent tsunami of March 11, 2011, caused immense damage and loss of life in Japan. It is estimated that over 15,000 people died and in excess of 2,500 persons are still unaccounted for (1, 2). The tsunami that struck the Fukushima Dai-ichi Nuclear Power Plant (NPP) led to breakdown of the reactor cooling systems, resulting in overheating of fuel ...
متن کامل[Radioactive caesium contamination in Inago and sustainability of Inago cuisine in Fukushima].
Inago (edible grasshoppers, Oxya spp.) was a popular food in the Fukushima area, before the reactor accident at Fukushima Dai-ichi Nuclear Power Station in March 2011. We investigated the radioactivity of Cs-134 and Cs-137 contained in Inago captured in Sukagawa, Motomiya, Inawashiro, Date, and Iidate in Fukushima prefecture in 2011 and 2012. The maximum combined radioactivity of Cs-134 and Cs-...
متن کاملImpact on marine environment of radioactive releases resulting from the Fukushima-Daiichi nuclear accident
Since several days, radioactive pollution was observed in the marine environment, at varying distances from the Fukushima-Daiichi power station. The main radionuclides regularly found in the sea water are (T = radioactive half-life): iodine 131 (T = 8 days), caesium 137 (T = 30 years), caesium 134 (T = 2.1 years), caesium 136 (T = 13.1 days), tellurium 132 / iodine 132 (T = 78 hours). Others ha...
متن کاملEvolution of radioactive dose rates in fresh sediment deposits along coastal rivers draining Fukushima contamination plume
Measurement of radioactive dose rates in fine sediment that has recently deposited on channel bed-sand provides a solution to address the lack of continuous river monitoring in Fukushima Prefecture after Fukushima Dai-ichi nuclear power plant (FDNPP) accident. We show that coastal rivers of Eastern Fukushima Prefecture were rapidly supplied with sediment contaminated by radionuclides originatin...
متن کاملRadioactive contamination of scintillators
Low counting experiments (search for double β decay and dark matter particles, measurements of neutrino fluxes from different sources, search for hypothetical nuclear and subnuclear processes, low background α, β, γ spectrometry) require extremely low background of a detector. Scintillators are widely used to search for rare events both as conventional scintillation detectors and as cryogenic s...
