AGREEMENT STATE REPORT - UNATTENDED RADIOGRAPHIC EXPOSURE DEVICE
The following report was received from the State of Ohio via email:
"On 12-11-2015, at 1738 EST, a radiographic exposure device was left unattended by licensee personnel and found by a customer's employee.
"Licensee's investigation indicated that their crew had performed 2 exposures at 2 minutes and 30 seconds on each exposure. Customer operations wanted to get their nuclear gauges back online as soon as possible so when the last exposure was complete the radiographer sent the assistant to let [the Customer] operations know they were complete. The radiographer then broke down everything and picked up the assistant [radiographer] at the ops building. They then drove back to the trailer where the radiographer went to the smoking area and the assistant went to the restroom. When the assistant came out they both went to back of the vehicle to grab film and they realized that the source was not in the vehicle. They immediately drove back to the area.
"While enroute back to the location of the radiography work they received a phone call from the customer's project manager that an employee had located an unattended exposure device. When the crew arrived, they determined the device was in the same place where they left it and the device was locked. Estimated time that the device was unsecured was 15 minutes. They surveyed the device, secured the device in the vehicle, and went back to the trailer. The licensee left a voice mail at ODH [Ohio Department of Health] at 1819 EST describing the situation.
"There was an immediate safety stand down put in place and no further exposures were to be made. On Saturday morning, 12/15/15, there was a conference call made at 0706 EST to the licensee's crews that were working. The crew that was involved in the incident were suspended from any radiographic work until a full investigation was made.
"On 12-14-2015, the [licensee's] RSO [Radiation Safety Officer] conducted a site visit and there was another safety meeting held with all crews on site.
"The exposure device was an 880 Delta made by QSA, the device contained 33.2 curies of IR-192, the source was made by QSA, model number 424-9.
"A more detailed report is expected from the licensee."
Ohio State NMED Report: OH150013
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.
