For the day when I can return: the future is one step away

Area of Science:

• Environmental Science
• Radiation Biology
• Community Health

Background:

• The 2011 Great East Japan Earthquake and subsequent Fukushima Daiichi nuclear power plant accident led to widespread evacuations.
• Iitate village residents were evacuated a month after the disaster, despite initial minimal earthquake damage.
• Conflicting media reports and expert advice created distrust and fear among evacuees regarding radiation safety.

Purpose of the Study:

• To assess personal radiation exposure and environmental safety in Iitate village post-disaster.
• To reconcile conflicting information about radiation levels and habitability.
• To inform the decision-making process for returning to the evacuated area.

Main Methods:

• Conducted personal measurements of ambient radiation dose in and around the home.
• Participated in dialogue seminars organized by the International Commission on Radiological Protection (ICRP).
• Measured radiation doses in wild plants cultivated for over 30 years.

Main Results:

• Personal radiation measurements provided a clear understanding of local radiation levels.
• ICRP seminars offered accurate information, clarifying the situation and addressing resident concerns.
• Radiation measurements of cultivated plants indicated no significant concerns for return.

Conclusions:

• Direct measurement and engagement with expert radiological guidance facilitated an informed judgment on safety.
• The study demonstrated that returning to Iitate was safe, dispelling fears amplified by the evacuation order.
• Personal dosimetry and participation in scientific dialogues are crucial for rebuilding trust and enabling informed decisions in post-disaster scenarios.
