Proposed triage categories for large-scale radiation incidents using high-accuracy biodosimetry methods

Area of Science:

• Nuclear preparedness
• Radiation oncology
• Disaster medicine

Background:

• Nuclear detonations cause mass casualties, necessitating rapid identification of individuals at risk of acute radiation syndrome (ARS).
• Current screening and triage methods for ARS are insufficient for large-scale nuclear incidents.
• Effective management requires distinguishing symptomatic patients from the 'worried-well' and accurately assessing radiation exposure.

Purpose of the Study:

• To review the efficacy of high-accuracy biodosimetry methods for population screening post-nuclear detonation.
• To evaluate current triage and medical guidelines for diagnosing and managing ARS.
• To propose a new triage system based on biodosimetry for improved mass casualty care.

Main Methods:

• Review of current high-accuracy biodosimetry techniques for population-level assessment.
• Analysis of existing triage categories and medical guidelines for ARS diagnosis and management.
• Development of a proposal for new triage categories utilizing biodosimetry data.

Main Results:

• High-accuracy biodosimetry offers a reliable method for assessing radiation dose in affected populations.
• Current ARS triage relies heavily on symptoms, which may delay appropriate care.
• Biodosimetry enables precise dose estimation, predicting ARS development and severity.

Conclusions:

• Replacing current symptom-based triage with biodosimetry-based categories is crucial for effective ARS management.
• Accurate whole-body exposure dose assessment facilitates optimized clinical decision-making and resource allocation.
• Implementing biodosimetry screening will enhance mass-casualty care capabilities following a nuclear disaster.
