ARI Becquerel Center

ARI Becquerel Center (ABC)

The ARI Becquerel Center measures nuclear radiation in soil, food, and water.
Since its beginning in 2012 it has supported food safety at ARI and the local community of Nasu and beyond.

The Asian Rural Institute opened the ARI Becquerel Center in the Nasu Seminar House on January 10, 2012. It is equipped to measure radiation in foodstuff and other substances.

The ABC is supported by the National Christian Council in Japan Ecumenical Disaster Response Office (JEDRO), Nasunogahara Resident’s Association for Radiation Protection (NRARP), the United Church of Canada (UCC), and dedicated local volunteers. 

Thus far, we have conducted more than 6,000 measurements and have given others advice from our experience and knowledge. Farmers and other food producers, and mothers with small children have come to take advantage of it. The equipment operators respond to the radiation concerns of the community by explaining the results of the measurements and providing advice based on the results.
