The following information was received by fax:
Radiographers set up a shot on a 2 inch diameter pipe which was laying in jackstands. They were working with a SPEC 150 exposure device containing a 42 Ci Iridium-192 sealed source. The jobsite was a large laydown yard in an industrial setting. The pipe fell from the stands and hit the guide tube. The guide tube was hit about 2 inches from the exposure end, and attempts at retracting the source were unsuccessful. The radiographers re-established boundaries and contacted the local [Assistant] RSO (ARSO) from the new boundary at approximately 1200 [EDT]. The ARSO is authorized to perform source retrieval for JANX. [The licensee] maintained surveillance while awaiting his arrival. The ARSO arrived onsite at 1240 [EDT], assessed the situation and interviewed the crew. He noted that the source tube appeared to have 2 crimps. The ARSO was in contact with the Corporate RSO in Michigan during the operation.
The ARSO used lead blankets to shield the source and surveyed. Survey revealed need for more shielding that was delivered to the site by [1345 EDT] and acceptable dose rate was achieved. He proceeded to remove the crimped section from the guide tube, observed that the drive cable was unaffected, connected the tube together with tape, and was able to retract the source into the exposure device. The event concluded by [1520 EDT]. The licensee will be making a full report with corrective actions within 30 days of the occurrence.
