The State provided the following information via email:
This is an incident involving a SPEC 150 exposure device with serial number 0288 that contained a 80 Ci source of Ir-192 (SPEC G-60 serial number NA-2006). On March 9, 2006 while radiographing a coupon, the exposure device was placed in contact with a welding lead. When the exposure device was cranked out the crankout cable formed an electrical conductor from the welding lead to the coupon. An arc and smoke was observed. The radiographer immediately returned the source to the shielded position. The radiographer approached the exposure device with a survey meter and determined the source was in the shielded position. The radiographer disconnected the source tube and replaced the safety plug. While attempting to remove the drive cable connector from the source pigtail, the connector came off. The radiographer replaced the dust cover cap, secured the exposure device in the transport container and called the main office. Neither radiographer received an excessive exposure. The exposure device and equipment were sent to SPEC for evaluation. SPEC stated that the integrity of the encapsulated source was not harmed, but the pigtail itself was unusable, and the source had to be disposed. The exposure device operated properly and was cleared for use by SPEC.
