PRESS RELEASE
Riverine 129I dynamics during high-flow events on the Abukuma River in Fukushima
A paper was published by a research group consisting of Associate Prof. Y. Wakiyama of Fukushima Univ., Assistant Prof. T. Matsunaka of Kanazawa Univ., and Associate Prof. K. Sasa of Tsukuba Univ., and was joint press released. ※Press release (PDF 489KB)
This study revealed that the concentration of iodine-129 in the Abukuma River is equivalent to the level before the Fukushima nuclear accident. In addition, this is valuable knowledge not only for the Fukushima nuclear accident but also for considering the global circulation of iodine-129.

Selected for the “2024 Best Paper Award” by the Botanical Society of Japan
The paper “Starch-dependent sodium accumulation in the leaves of Vigna riukiuensis” by Yusaku Noda of QST (National Institutes for Quantum Science and Technology), an ERAN researcher, and his collaborators was selected for the 2024 Best Paper Award by the Botanical Society of Japan.
The gist of the paper is that one of the salt-tolerant species, Vigna riukiuensis, accumulates high amount of sodium in the leaves and its tolerance was derived from the Na-trapping system by starch granules. Please take a look.

Selected as the cover of the journal “Analytical Chemistry”
A paper titled “Rapid Method To Determine 137Cs, 237Np, and Pu Isotopes in Seawater by SF-ICP-MS” published by ERAN member was selected as the cover of the journal “Analytical Chemistry”.
The gist of the paper is that they established a chemical separation method for minute amounts of artificial radionuclides Np, Pu, and Cs in seawater, and succeeded in quantifying the concentration of Np-237 in Pacific seawater off the coast of Fukushima for the first time in the world. Please take a look.
