Objective: To investigate the feasibility of using single void urine samples to monitor internal radiation exposure of first responders and large populations in the event of a radiological incident involving the intentional dispersal of 210Po. Methods: Urinary excretion of 210Po was evaluated and organ absorbed and effective doses were calculated subsequent to an acute unit intake of 210Po. Results: 210Po can be detected in single void urine samples at levels sufficient to detect effective dose below recommended limits. Minimum intakes of 210Po that would result in clinically significant effects were estimated. Conclusions: Collection and analysis of single void urine samples is adequate to identify persons who may be exposed in the event of a radiological emergency involving 210Po. Also, the first responder limit appears to be sufficiently protective to prevent clinically significant deterministic effects.
