Expedited Processing of Radiation Dose Assessments for Military Personnel of the Enewetak Atoll Cleanup Project (1977-1980)

Abstract

This report serves as the technical basis document for performing expedited processing of radiation dose assessments (RDAs) for veterans who participated in the Enewetak Atoll Cleanup Project (ECUP) from 1977 to 1980. Approximately 6,000 Military Service members of the United States Department of Defense participated in the cleanup project. Expedited processing would result in the assignment of upper bound, group-based radiation doses to ECUP veterans without the need for individualized RDAs. To create an expedited processing system for ECUP, Expedited Processing Groups (EPGs) are identified, and maximized upper-bound doses are estimated for each group. The majority (86 percent) of the This report is a brief summary of a study that is in preparation for publishing. For the full technical report see Johnson et al. (n.d.), Retrospective Review of Injuries Sustained by Seated Occupants in U.S. Army Rotary-Wing Mishaps from January 1990 through December 2018. The aim of this study is to identify injury trends to multiple body regions, and analyze the rates of different occupant injury outcomes for nine rotary-wing aircraft from mishap date retrieved from the US Combat Readiness Center Mishap Database. Efforts from this study will help inform and guide the research and development of improved injury mitigation technologies. From the reported injuries that were categorized by airframe and body region, it was found that the torso had the largest proportion of injury for five out of the nine aircraft and the head had the largest proportion of reported injuries for three out of the nine aircraft.estimated EPG organ, skin, and lens of the eye doses meet the suitability criteria for use in expedited processing.
