Interdisciplinary Study on
Environmental Transfer of Radionuclides
from the Fukushima Daiichi NPP Accident

福島原発事故により放出された放 射 性 核 種の環境 動 態に関する学 際 的 研 究

ISET-R Symposium was held at Advanced
Research Laboratory Building A in University ofTsukuba on January 9 and 10, 2015. A total of 122participants, including ISET-R members, students,and researchers invited from abroad took part in
the two-day symposium. Active discussions andexchange of views were presented, aiming todevelop a new research field that will lead theworld.
On the first day of the “InternationalSymposium on Interdisciplinary Study on
Environmental Transfer of Radionuclides from theCourtery of Japan Geoscience Union

Fukushima Daiichi NPP Accident,” principal
investigators of the research groups from A01-1 to
A04-8 reported on their research results regarding
the grasp of current contamination level ofFukushima-derived radionuclides and theclarification of transfer and diffusion processes ofradionuclides.
The guest speakers from abroad, who engage
in research in isotopes and environmental
dynamics, made comments on the presentations byprincipal investigators and displayed their views on
the future outlook.

Poster Session
Poster Session was held
during lunch break. On thef i r s t d a y, E n g l i s h p o s t e r ssummarizing research resultsof each group were posted. On
the second day, many of theISET-R members introduced
their research results.
In front of more than 80
posters displayed, speakers
discussed their findings andideas with fellow participants,
offering great opportunities todeepen mutual understandings.
Poster Session

Conference Party
A conference party was held at the end of thefirst-day symposium, bringing together over 100
researchers. An award ceremony was held to honor
participants of the ISET-R programs fostering
young researchers, which is one of the moste m p h a s i z e d t a rg e t s o f I S E T- R . T h i s y e a r,
certificates were offered to Dr. Yoshifumi
Wakiyama at University of Tsukuba and Ms.
Shizuka Matsunaga at Osaka University by thehead investigator.
We hope that more and more young researchers
join the programs and become a recipients of theaward next year.

Award Ceremony

Comments from the award winners■Dr. Yoshifumi Wakiyama at University of Tsukuba
I was able to gain valuable experience throughthese programs for young researchers. I would liketo express my sincere gratitude to the professorsand persons concerned. I will make the most of thisexperience in my future research work.
■Ms. Shizuka Matsunaga at Osaka University
My main work at laboratory is to measurer a d i o a c t i v i t y. I n t h e t r a i n i n g p r o g r a m s I
participated, I had opportunities to collect samples
in the field and to analyze samples I have nevertouched before. I realized “seeing is believing”

Dr. Wakiyama (left) and Ms. Matsunaga (right)

through trainings in different research field. Having
greatly inspired by students and researchers fromdifferent universities, I made a fresh resolve todeepen my research. My heartfelt gratitude goes toprofessors and administrative staff who havesupported this program.

Day 2 (January 10, 2015)

International Symposium on Interdisciplinary Study on Environmental
Transfer of Radionuclides from the Fukushima Daiichi NPP Accident
In the afternoon, the researchers invited fromexternal research institutions, who play an
influential role in Center for Research in Isotopes
and Environmental Dynamics, displayed theirviews on developments and outlook of the research
and a valuable exchange of views was held amongparticipants.

The morning session began with the report oninterim evaluation and the future plan of theresearch projects by the head investigator, Professor
Yuichi Onda at University of Tsukuba, followed by
the progress reports and results presented by theresearch group recruited from the public.

Future plan of the research fieldYuichi Onda (Head investigator)

The following four points were raised as the most criticalissues to deal with in the future promotion plan.
1. Embodiment of a new research field by promoting
collaborative research
2. Promotion of international collaboration
3. Fulfillment of fostering young researchers
4. Transmission of information
