Temporal variation of iodine-129 concentrations in kelps (Saccharina) from coastal waters off northern Japan
Autor: Shinji Oikawa, Jun Misonoo, Masatoshi Yamada, Masashi Kusakabe, Takahito Ikenoue
Publikováno v: Marine Pollution Bulletin. 161:111775
Concentrations of 129I and 127I in kelps (Saccharina) collected from coastal waters off northern Japan were monitored from 2007 to 2019. During the 2007–2008 test operation of the Rokkasho nuclear fuel reprocessing plant, 129I discharge from the pl

Publikováno v: Applied Radiation and Isotopes. 81:340-343
Our method based on low background γ-spectrometry enabled the measurement of low radiocesium concentrations in only 20 L of seawater. In May 2011 after deposition of radiocesium, (134)Cs concentration in surface water within the Sea of Japan was con

Publikováno v: Journal of Environmental Radioactivity. 102:302-310
A radioactivity survey was launched in 1991 to determine the background levels of 239+240 Pu in the marine environment off a commercial spent nuclear fuel reprocessing plant before full operation of the facility. Particular attention was focused on t

Publikováno v: BUNSEKI KAGAKU. 57:763-769
For the purpose of marine environmental radioactivity monitoring, stable Cs and 137Cs concentrations were obtained from 214 marbled flounder (Pleuronectes yokohamae) samples collected from off the coast of Ibaraki prefecture in Japan in 2005 and 2006
