The following information was received via E-mail:
On February 20, 2017, the licensee's radiation safety officer (RSO) notified the Agency [Texas Department of State Health Services] that one of its New Mexico radiography crews was performing radiographic operations on a pipeline that was being built in Reeves County, Texas. The crew finished work at one section and put the Spec 150 radiography device on the tailgate of their truck while they drove down the pipeline right-of-way to their next location. Unbeknownst to the radiographers, the device fell off the tailgate. The licensee and crew learned of the loss after a contractor found the device, picked it up, put it in the back of his pickup, and took it to another of the licensee's radiography crews who was also working on the pipeline. That crew called their site RSO who then called the crew who lost the camera.
The camera was surveyed and readings were as expected. The source was in the fully shielded position and the safety plug was in the front of the camera. Based on calculations by the RSO on February 21, 2017, the contractor's exposure does not appear to have exceeded any regulatory limit.
An investigation into this event is ongoing and further information will be provided as it is obtained in accordance with SA-300.
The device was a Spec model 150, serial No.: 1778 containing a 60 Curie (current activity) Iridium-192 source, serial No.: YA0302.
Texas Incident No.: I-9466
