7 Section 1. Introduction 1.1 Background Soon after the earthquake and tsunami in Japan that occured on March 11, 2011, and subsequent release of radioactive materials from the Fukushima Daiichi Nuclear Power Station (FDNPS), the Department of Defense (DOD) responded by providing humanitarian assistance and disaster relief in Operation Tomodachi. The DOD established the Operation Tomodachi Registry (OTR) as part of DOD s environmental health surveillance registries and the Operation Tomodachi Registry website. The OTR is overseen by an OTR Steering Group and four working groups. The Dose Assessment and Recording Working Group (DARWG) was tasked with developing radiation dose assessments for a DOD-affiliated population of some 70,000 individuals. To estimate radiation doses, the DARWG identified, evaluated, and selected available environmental and personal radiation monitoring data. The DARWG reviewed the results of environmental radiation measurements reported by DOD, Department of Energy (DOE), and Government of Japan (GOJ) teams (Cassata et al., 2012; AIPH, 2011; MEXT, 2011; NNSA, 2011). Those measurement results are available on line for DOD and DOE at or at for GOJ. Results included external exposure rates and activity concentrations in air, water, and soil from measurements taken at or near locations where DOD-affiliated individuals worked or lived. Using these results, the DARWG prepared datasets for input to calculation worksheets developed to estimate both external and internal radiation dose. These datasets were comprised of measured, adjusted, interpolated or extrapolated quantities for each hour of the period from March 11 to May 11, 2011 as described in Cassata et al. (2012). The dose results for individuals located on the main island of Japan were reported in Cassata et al. (2012) and were included in the OTR (ASD(HA), 2011). Overall, the input datasets were used in dose calculations discussed in the following reports: Radiation Dose Assessments for Shore-Based Individuals in Operation Tomodachi, Revision 1, DTRA-TR (R1) (Cassata et al., 2012). Probabilistic Analysis of Radiation Doses for Shore-Based Individuals in Operation Tomodachi, DTRA-TR (Chehata et al., 2013). Radiation Internal Monitoring by In Vivo Scanning in Operation Tomodachi, DTRA-TR (Cassata et al., 2013). Radiation Dose Assessments for the Embryo, Fetus, and Nursing Infant during Operation Tomodachi, DTRA-TR (Falo et al., 2013). Radiation Doses for Fleet-Based Individuals in Operation Tomodachi, DTRA-TR (Marro et al., 2013). 3

8 1.2 Purpose The purpose of this data compendium is to provide the datasets that the DARWG used in its dose calculations so they are available for review, examination and use by interested parties. The datasets include radiation dose or exposure rates and activity concentrations in air, water, and soil, which were used to calculate the radiation doses published in the reports listed above. The values in this Data Compendium comprise: Direct and derived values from measurements. Surrogate data, i.e., measurement results from one location assigned to another location. Values estimated through the use of data models that are based on measured values from either of the above sources. Figure 1 contains a conceptual diagram of the process for preparing the input datasets included in this Data Compendium and for calculating the doses reported in the OTR. Measurements in Media by DOD, DOE, and GOJ Evaluate/ Select Data Data Compendium Input datasets (dose rate; radioactivity in air, water, and soil) Calculate Doses Reported Doses Figure 1. Process for preparing and using input datsets for doses reported in the OTR 1.3 Radiation Dose Input Datasets The measurement results originally reported by various organizations were used to produce the input datasets listed in this Data Compendium. External dose or exposure rate measurements reported by various DOD and DOE organizations (NNSA, 2011) were combined with measurement data reported by the GOJ (MEXT, 2011) to produce values for each hour in the two-month assessment period. Activity concentration values in air were derived from measurements on samples collected by DOD, DOE, or the Comprehensive Test Ban Treaty Organization (Cassata et al, 2012). The results were used directly, as surrogate data for locations where measurements were not taken, or as the basis for models that used interpolation, extrapolation, decay, and other methods to estimate concentrations on days without measurements (Cassata et al, 2012). Activity concentration values in water were derived from measurements made by the GOJ (MEXT, 2013) or DOD for municipal water systems that served the OTR population within DARWG locations. The water activity concentrations were generally used without adjustment (Cassata et al, 2012). Activity concentration values in soil reported by DOD were used as the basis for modeling to estimate values for days when measurements were not made or when there were multiple measurements on a single day (Cassata et al, 2012). 4

9 Note: All time periods and isotopes where data were not available or where the results of the measurements were below the detection limits of the instruments used are labeled with an en dash ( ). All dates and times are in Japan Standard Time (JST). 5

11 Section 2. Activity Concentrations in Air Table 1 through Table 5 include input datasets of activity concentration values in air for the International Monitoring Station-Takasaki, Air Base, Sendai, Ishinomaki, and Air Base. The Air Base input datasets were also used in the calculation of doses for, Naval Air Facility, and Naval Base (Cassata et al., 2012). These tables contain the values used for dose calculations from inhalation of radioactive materials in the air. Inhalation doses are included in the results reported on the OTR (ASD(HA), 2011) website. 7

Activity Concentrations in Drinking Water Table 6 through Table 12 include input datasets of activity concentrations in water for the, Hyakuri Air Base,, Air Base,, Naval Air Facility, Naval Base, respectively. All drinking water results reported for Air Base, Yamagata,, Marine Corps Air Station, and Naval Base were below detection limits. These tables contain values used for dose calculations from ingestion of radioactive materials in the drinking water. Doses from the water ingestion are included in the results reported on the OTR (ASD(HA), 2011) website. Table 6.
