The licensee reported that there was a stuck source at a temporary job site [Motiva Refinery] in Perth Amboy, NJ. The exposure device involved was an Amersham-660B [Model A424-9] which contained a 17-Curie
Iridium-192 source.
When the source stuck in the extended position, the crew tried unsuccessfully to retract it. The workers then secured the area of concern and put up a controlled boundary to limit personnel exposure to 2 mr/hr or less. Licensee notified AEA-QSA [aka QSA-Global, Inc.] to come to the work site and repair or replace the defective equipment. It is unknown if any of the workers were overexposed due to this incident, however, licensee suspects they were not. Licensee will be evaluating the workers personal dosimeters, and other instruments, to ensure accurate readings of personnel exposure.
