| ENS 55141 | 30 December 2020 06:00:00 | Agreement State | Lost Density Gauges | The following was report received from the state of Texas via email: On December 30, 2020, the licensee reported that during an in-depth audit it had been unable to locate two ThermoFisher model 5192 densitometers, each containing 200 milliCuries of cesium-137. The licensee had records showing it possessed them at one of its facilities more than two years ago, but it could neither physically locate them nor find any records showing their disposition. The licensee has continued its investigation but still has not determined the location or disposition of the devices. Serial Numbers for the two devices are B7713 and B7850. More information will be provided as it is obtained in accordance with SA-300. Texas Incident # I-9831. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| ENS 54984 | 5 November 2020 06:00:00 | Agreement State | Stolen Nuclear Gauges | The following is a summary of information received from the Texas Department of State Health Services (the Agency) via email: On November 5, 2020, the Agency was notified by the licensee that three of their nuclear density/level measurements gauges had been stolen from one of their storage sites. The storage site had been vandalized and various pieces of equipment were damaged as well. The licensee has contacted local law enforcement about this incident. The gauges contain Cs-137 sources. The total activity of the missing sources is estimated to not exceed 200 mCi. The licensee does not have any additional information regarding the incident or gauges at this time. Texas Incident Number: 9808
On November 9, 2020, the licensee provided additional information on the stolen gauges. All gauges contained cesium-137 sources. Two of the gauges were Thermo Fisher model 5192 gauges. One of the two gauges contained a 250 milliCurie (mCi) (original activity now 215 mCi) source and the other contained a 200 mCi (now 162 mCi) source. The third gauge was a Thermo Fisher model 5190 gauge containing a 200 mCi (now 166 mCi) source. The gauges had been stored in a locked cage on the licensee's site. The gauges were still installed on the pipes they were used on. The licensee stated the last time the gauges were seen was September 1, 2020. The Agency instructed the licensee to notify local scrap yards of the theft and provided them with a copy of the attached picture. The Agency has requested additional information from the licensee. Additional information will be provided as it is received in accordance with SA-300. Notified R4DO (Dixon), ILTAB (email), NMSS Events Notification (email), and CNSNS-Mexico (email)
On December 6, 2020 at 2033 (CST) hours the Agency was notified by the licensee that the three devices reported stolen in this event have been recovered. The gauges are in the possession of the licensee and are locked inside a secured location. Additional information will be provided through NMED as it is received.. Notified R4DO (Gepford), ILTAB (email), NMSS Events Notification (email), and CNSNS-Mexico (email) THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury.

| ENS 51748 | 18 February 2016 06:00:00 | Agreement State | Agreement State Report - Lost Density Gauge | The following was received from Texas via email: On February 22, 2016, the Agency (Texas) received notice that while under reciprocity in Louisiana, the licensee had lost a Thermo Fisher model 5192 (sn B8191) with 200 milicuries of Cesium-137 (sn 5854CP). Exposure to the public is unlikely due to the design of the device. It is not known whether the device was lost or stolen. The Louisiana Department of Environmental Quality is conducting the investigation. Addition information will be provided as it is received in accordance with SA-300. The device was lost in Louisiana but reported to Texas by a Texas licensee. The state of Texas notified the state of Louisiana and the NRC. Louisiana will conduct an investigation of the issue.
