The "Lesson #3.11 - Our Choice After Seven Years" panel exhibit features scientific data related to the 2011 Great East Japan Earthquake and the subsequent nuclear accident. In addition to updated information on radioactive contamination, the panel exhibition provides information related to preparations on major earthquakes, and challenges surrounding energy production.
The Hazards of a Magnitude 9 Earthquake
The exhibit provides information related to the size of the shift on the surface of the fault where the earthquake occurred, as well as the distribution of earthquake seismic intensity throughout Japan, and examines the risks related to another earthquake occurring,
Protecting Yourself, Protecting Everyone
Countermeasures created by national and local governments alone were not enough to prevent all risks related to the earthquake. This exhibit examines the necessity of the concepts of "self-help", "cooperative help", and "public help" that are required in order to protect human lives and assets.
Decreasing Levels of Land-Based Nuclear Pollution/Spreading and Weakening Levels of Ocean-Based Nuclear Pollution
The situation surrounding the nuclear pollution released from the Fukushima Daiichi Nuclear Accident has changed greatly over the past 7 years. This exhibit features information about the mechanisms related to the diffusion of the radioactive cesium released onto the land and into the sea and provides current information about this issue. It also features data relating to the effects that pollution has had on agricultural and marine products.
Protecting Food from Nuclear Pollution
After the earthquake, agricultural standards of <=100 Bq per kilogram were put in place to limit concentrations of cesium in food. Areas that were affected by the pollution have taken measures to prevent contamination from radioactive materials and are using radiation testing to ensure safe food production, but has agriculture really recovered? Agricultural products such as cucumbers and rice are used as examples, with current radiation levels and prices displayed as a way of examining this issue.
Our Increasing Reliance on Fossil Fuels
How have Japan's energy plans progressed in the period before and after the earthquake? This exhibit considers the risks related to energy production that were made clearly evident by the Fukushima Daiichi Nuclear Power Accident, as well as the current state of energy production.
The Creation of Renewable Methods of Energy Production
As the risks related to future climate change continue to increase, countries throughout the world are shifting towards renewable methods of energy production. Since the earthquake, political measures have been put into place that recommend a large-scale shift towards renewable electricity production in Japan. As these measures begin to be introduced, more attention is being paid to the challenges surrounding their cost and stability. This area exhibits data related to the current and future outlook of renewable energy solutions.
