The Biodosimetry Assessment Tool (BAT) is a computer program developed by the Armed Forces Radiobiology Research Institute (AFRRI) as an aid to provide early diagnostic information (clinical signs and symptoms, physical dosimetry, etc.) to health care providers responsible for the initial management of radiation casualties after a major radiation incident. It is designed primarily to permit collection, integration, and archiving of data obtained from patients accidentally exposed to ionizing radiation. BAT also provides an early estimate of radiation dose using the timing of prodromal symptoms, clinical data, and various aspects of the time-dependent hematology profile. Collection of relevant data is facilitated by use of structured templates and user-friendly software. The BAT software is illustrated here using five historical cases from the U.S. Radiation Accident Registry maintained by the Radiation Emergency Assistance Center/Training Site (REAC/TS) for the U.S. Department of Energy.

Radiation exposures from accidents, nuclear detonations or terrorist incidents are unlikely to be homogeneous; however, current biodosimetric approaches are developed and validated primarily in whole-body irradiation models. A workshop was held at the Armed Forces Radiobiology Research Institute in May 2008 to draw attention to the need for partial-body biodosimetry, to discuss current knowledge, and to identify the gaps to be filled. A panel of international experts and the workshop attendees discussed the requirements and concepts for a path forward. This report addresses eight key areas identified by the Workshop Program Committee for future focus: (1) improved cytogenetics, (2) clinical signs and symptoms, (3) cutaneous bioindicators, (4) organ-specific biomarkers, (5) biophysical markers of dose, (6) integrated diagnostic approaches, (7) confounding factors, and (8) requirements for post-event medical follow-up. For each area, the status, advantages and limitations of existing approaches and suggestions for new directions are presented. © 2010 by Radiation Research Society.

A sample of tritiated lanthanum nickel aluminum alloy (LaNi4.25Al0.75 or LANA.75) similar to that used at the Savannah River Site Tritium Facilities was analyzed to estimate the particle size distribution of this metal tritide powder and the rate at which this material dissolves in the human respiratory tract after it is inhaled. This information is used to calculate the committed effective dose received by a worker after inhaling the material. These doses, which were calculated using the same methodology given in the U.S. Department of Energy Tritium Handbook, are presented as inhalation intake-to-dose conversion factors (DCF). The DCF for this metal tritide was determined to be 9.4 × 10 Sv Bq, which is less than the DCF for tritiated water. Therefore, the radiation worker bioassay programs designed for tritiated water are adequate to monitor for intakes of this material. Copyright © 2012 Health Physics Society. Source
