Data related to potential radiation exposures to U.S. military personnel in Japan following the accident at Fukushima Daiichi Nuclear Power Station (FDNPS) in 2011 have been added to the RACER Data Analysis and Risk Calculation Tools. These data, provided in the Defense Threat Reduction Agency (DTRA) “Operation Tomodachi Registry: Radiation Data Compendium”, include measured concentrations in soil, air, and tap water, as well as dose rates from survey meters.
