| Title | Lost Then Found Category 2 Radiography Exposure Device |
| Event Description | The following information was received via E-mail:
The licensee RSO [Radiation Safety Officer] reported that a Mistras technician lost an INC IR-100 radiography camera, serial number 6744, on April 1, 2019, between approximately 0000 and 0100 PDT. The camera contained an Ir-192 sealed source, number 159E, with 85.3 curies. The radiography camera was left unsecured on the tailgate of a company darkroom vehicle upon departing the licensee's Long Beach office. The camera was being transported to the Chevron refinery in El Segundo for radiographic operations during the night. The lost camera was reported to the Long Beach office (at approximately 0110 PDT) by the technician upon arrival at the El Segundo refinery, and a radiography crew was sent from the Long Beach office to search the route taken by the first individual. The camera was found and recovered by the radiography crew approximately 0130 PDT on the breakdown lane of limited-access CA Hwy 91 westbound, approximately 4 miles from the Long Beach facility (near Wilmington Ave). The recovered radiography camera was returned to the Long Beach facility, where a leak test was performed, showing no leakage. The radiography camera was sent to a repair facility for further inspection. RHB [Radiation Health Branch] will investigate the cause of the incident, take appropriate enforcement action, and ensure appropriate corrective actions by the licensee.

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.
