| event text = [A] technician working with a 113 Ci Ir-192 source set off high radiation alarms at [the QSA Global facility] which caused the immediate evacuation of the building. Radiation surveys outside the building indicated a dose rate of approximately 3 Mr/hr at a distance of 25 feet from the exterior of the building. Radiation safety staff performed a source retrieval to recover the source and place it in a shielded container; the building was reoccupied approximately 30 minutes later. | | event text = [A] technician working with a 113 Ci Ir-192 source set off high radiation alarms at [the QSA Global facility] which caused the immediate evacuation of the building.

Preliminary investigation of the technician indicated his electronic dosimeter (worn on the side of the body closest to the source) showed an exposure of 720 mRem. The technician was not wearing his extremity ring badge at the time, however the radiation safety officer calculated a maximum exposure to the tips of the maximally exposed fingers to be approximately 2 Rem. Dosimetry for both the technician involved and another that was nearby when the incident occurred have been sent to the vendor for immediate processing. | Preliminary investigation of the technician indicated his electronic dosimeter (worn on the side of the body closest to the source) showed an exposure of 720 mRem.
