Atmospheric deposition of Pu isotopes from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident has been observed in terrestrial environment around FDNPP site; however, their marine not studied. The possible contamination attracted great scientific and public concern. To fully understand this to environment, we collected sediment core samples within 30 km zone site western North Pacific about two years after accident. ((239)Pu, (240)Pu, (241)Pu) radiocesium ((134)Cs (137)Cs) were...
Six years after the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, data for 236U and 236U/238U have remained limited to a few heavily contaminated samples. In present study, activities of 236U, 239Pu, 240Pu, along with other U isotopes in 46 soil samples both lightly by this accident were measured inductively coupled plasma-mass spectrometry (ICP-MS) triple-quadrupole ICP-MS. The atom ratios these range (0.469-24.4) × 10-5 Bq kg-1 ((0.099-1.35) 10-7), respectively. Higher...
Abstract 135 Cs/ 137 Cs is a potential tracer for radiocesium source identification. However, due to the challenge measure Cs, there were no data available Japanese environmental samples before Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. It was only 3 years after accident that limited values could be measured in heavily contaminated samples. In present study, activities of 134 and along with their ratios 67 soil plant lightly by FDNPP combining γ spectrometry ICP-MS/MS. The...
An acidic leaching method using HNO3 is widely employed to release the global fallout Pu from soil samples for further chemical separations in radioecology and toxicology studies many applications as a useful tracer. In method's sample ash treatment step decompose organic matter soil, various ashing temperatures (400-900 °C) are used; however, effect of temperature on accurate analysis has not been well investigated. this study, two standard reference soils (IAEA-soil-6 IAEA-375) were used...
Obtaining Pu background data in the environment is essential for contamination source identification and assessment of environmental impact released from Fukushima Daiichi nuclear power plant (FDNPP) accident. However, no baseline information on isotopes Prefecture has been reported. Here we analyzed 80 surface soil samples collected central-eastern Japan during 1969-1977 (239+240)Pu activity concentration (240)Pu/(239)Pu atom ratio to establish before FDNPP We found that concentrations...
Neptunium-237, owing to its long half-life (t1/2 = 2.14 × 106 year) and similar conservatism 137Cs, has the potential replace 137Cs for water mass circulation studies on decades even longer time scales. A new method determination of 237Np, Pu isotopes in seawater samples was proposed solve difficulty 237Np analysis seawater. The developed includes separation technique ammonium phosphomolybdate (AMP) adsorption anion exchange chromatography Pu, a measurement gamma spectrometry SF-ICP-MS...
