The ongoing crisis in Japan has highlighted our collective need for trusted information.

This site is not meant as a replacement for government or nuclear agencies. Our hope is that data sets from various places can provide additional context to the official statements in these rapidly changing events. We welcome your thoughts on how to improve the site, and appreciate your work to provide a richer understanding of these events.

If you are a scientist or member of a government agency, and would like to contribute data in an official capacity, please contact us here.

While we are gathering our own data, we want to recognize the efforts of others who are actively seeking, parsing and making data available for others to use.

While this site is focused on providing unbiased data regarding the nuclear crisis, we do not wish to minimize the very real needs of people affected by these events. Please consider donating via the following organizations.
