DOD launches site estimating radiation in Japan


The Defense Department launched the Operational Tomodachi website on Wednesday that provides location-based radiation dose estimate reports for the DOD-affiliated population on or near mainland Japan.

The new site comes following the Great East Japan Earthquake and Tsunami of March 11, 2011.

The Operation Tomodachi Registry, which will be housed in a secure database containing the names, locations and radiation doses for all members of the DOD-affiliated population, will be completed by Dec. 31, 2012. Personally identified information will be omitted from this website.


After extensive environmental monitoring and analysis, it has been determined that none of the nearly 70,000 members of the DoD-affiliated population – service members, DOD civilian employees and contractors, and family members of service members and civilian employees – who were on or near the mainland of Japan between are known to have been exposed to radiation at levels associated with adverse medical conditions.

The website also includes information on the event, DOD’s response to the crisis, and answers to frequently asked questions. By the end of the calendar year, individuals in the registry may request a dose assessment that is individually tailored for them, based on more detailed location data that they can provide using the “Contact Us” function on the Operation Tomodachi Registry website.
