The shutter was in the open position (which was verified with a survey meter) and could not be closed. The device is a Berthold LB8010 densitometer. The device's source is a cesium-137 source with an activity of 20 mCi (original activity). The incident happened on a wellsite near Pearsall, Texas. The device was transported in a Type A container to the licensee's facility and put into storage. The licensee reported the device will be disposed of on November 15, 2026.

"On July 15, 2026, the Agency received a notification from the licensee regarding a stuck source shutter on a density gauge. The gauge, a Vega SHF2 Model, contains a 200 millicurie cesium-137 sealed source. The licensee reported that the gauge was found with the source shutter stuck in the open position by technicians conducting routine shutdown operations at the facility on July 14, 2026. Open is the normal operating position. The licensee stated that no worker or members of the public received an unintended radiation dose as a result of this event.

EN Revision Text: AGREEMENT STATE REPORT - LOST SOURCE

The following information was provided by the Texas Department of State Health Services (the Department) via phone and email:

"On August 11, 2026, the Department received notification from the licensee regarding a missing industrial radiography camera. The camera, an Industrial Nuclear Company [model] IR 100, contains a 90 Curie iridium-192 sealed source. The licensee stated that the trainer placed the camera at the back of the truck around 0600 CDT while preparing to leave the licensee's Wichita Falls office for a temporary jobsite in Weatherford [Texas]. The trainer did not place the camera inside the transport box and did not close the vehicle tailgate before departing. The trainer drove to the destination and realized upon arrival that the camera was missing and that the vehicle's tailgate was down. The radiation safety officer (RSO) stated that a team has been searching for the camera since this morning and will continue the search throughout the evening. The RSO stated that local law enforcement has been notified of the missing radioactive source in Wichita Falls. Additional information will be made available in accordance with SA-300 Reporting requirements."

The following information was provided by the Texas Department of State Health Services (the Department) via phone and email:

"On August 12, 2026, two department investigators conducted a search for the missing camera and found it in Mineral Wells [Texas] at 1342 CDT. The source was found in a culvert at the intersection of highway 281 and 1821. The licensee has been informed and is enroute to collect the camera. Based on the location where the source was found, it does not appear that any individual would have received an exposure that would have approached any limit"

The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:

The source was found in the fully shielded position and there was no damage to the radiography camera.

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.

AGREEMENT STATE REPORT - STUCK SHUTTER

The following information was provided by the Pennsylvania Bureau of Radiation Protection (the Department) via email:

"On August 10, 2026, [at approximately] 1930 [EDT], a radiographer was working at the licensee's permanent location and could not fully retract the source into the camera. The camera is a QSA Model 880 with a source assembly model QSA Model A424-9. It contains approximately 22 Ci [0.8 TBq] of Ir-192. The source was stuck [approximately] one inch from the locked position, so it was partially shielded. They were able to disconnect the crank and pull the source back into the locked position. Since then, the camera seems to be operating correctly, and the issue was with the crank. The licensee spoke with the manufacturer (QSA), and the maintenance technician they spoke to [also] seemed to think it was an issue with the crank. They will be sending the crank to QSA on August 12, 2026, for inspection and repair if possible."
