Overview

Experimental evaluation demonstrates electron paramagnetic resonance protocols for dose reconstruction in human tissues, highlighting viable triage strategies for mass-casualty radiation incidents.

Key Points

To evaluate electron paramagnetic resonance (EPR) dosimetry methods across biological tissues and establish standardized protocols for retrospective dose assessment during radiation accidents.
Conducted experimental analyses using X-band (9.4 GHz) spectrometry on biological samples including human hair, nails, and tooth enamel.
Evaluated the operational performance of higher-frequency Q-band (34 GHz) spectrometers and assessed L-band (1.1 GHz) instrumentation for noninvasive in-vivo measurements.
Formulated sample processing recommendations from initial collection to final absorbed dose reporting.
Confirmed tooth enamel as an established standard and demonstrated reliable signal-to-dose correlation in fingernails and hair for emergency triage.
Determined that Q-band spectrometry improves measurement sensitivity for micro-samples, while L-band systems enable feasible in-vivo dose evaluation without sample preparation.
