Background/Aim: A mobile system allowing hospital medical personnel to prepare for the administration of radiation mitigators prior to receiving casualties is desirable. Materials and Methods: We evaluated a portable spectroscopic personal radiation detector for use as an ambulance-based unit for early detection and identification of gamma radiation. We tested the sensitivity, time-to-identification, and radionuclide identification accuracy rates, change in detector response to vehicle operation, interference from cardiac equipment, and internal versus external radiation source location. Results: We detected radiation sources in each of 119 trials using a humanoid phantom in a moving ambulance with a primary radionuclide identification accuracy of 96%. Typical identification time was around two minutes (149 +/- 95 s). Conclusion: Our observations suggest this mobile system is a potential pre-hospital arrival tool allowing for rapid preparation of radiation mitigators.
