Ten Years after 311
Ten years have passed since the Great East Japan Earthquake and subsequent nuclear incident. What has changed and what hasn't changed in these past 10 years?
This map is a visualization of the results of radioactive material tests on food in Japan over 10 years. The rate of samples that exceed national standards is colored by city.
Keep in mind that the half-life of cesium137 in the environment is about 30 years. In the last 10 years, it has actually decreased by only about 20%
We need to keep monitoring this and ensure that updates are made public.
About the Work
This interactive map shows the rate of samples that exceed national standards (since April 2012) in color for each city in the Tohoku, Kanto, and Chubu region prefectures. Hokkaido, Kansai, Chugoku, Shikoku, and Kyushu / Okinawa were excluded because they exhibit almost no effect from radioactive substances. The excess rate is visualized monthly.
