In March, 2011, the accident of the Fukushima Daiichi nuclear plant began following the Eastern Japan earthquake.
Radioactive contamination was invisibly spread in eastern Japan and wider areas. In response to these circumstances,
a citizens’ movement for radioactivity measurement began and grew rapidly, run by people who volunteered to check
the contamination of food and other materials they produced and consumed. In some cases, volunteers shared
the cost of purchasing measurement instruments, while others asked for donations and applied for grants,
and ultimately many groups started to measure food, water, and soil in their areas.
In 2012, at a research exchange meeting on radioactive measurement conducted by the Takagi Fund
for Citizen Science for aid recipients and applicants, the Tokai No Nukes Network for
Future Generations Citizens' Radiation Measuring Center （C-lab) in Nagoya conceived the idea of producing a simple database
and systematized mapping of the measurement data.
C-lab initiated the project of constructing a full-scale database of independent radioactivity measurement laboratories.
In order to achieve this objective, C-lab and Takagi Fund consulted with Kodomomirai Radiation Measurement Station
for Children and Future (Kodomira RMS) which was managing the network of independent radioactivity measurement
laboratories in Japan.
These groups started to work together to establish and launch a joint food radioactivity measurement data site.
