| Event Description | The following was received from the Texas Department of State Health Services (the Agency) via email:
On October 12, 2020, the licensee notified the Agency that on October 10, 2020, one of its technicians completed a job at a temporary job site in Dallas, Texas, and drove to another temporary job site in Venus, Texas. Upon arriving, the technician found he did not have the Humboldt 5001 EZ moisture/density gauge in his truck. The gauge contained an 8 milliCurie cesium-137 and a 40 milliCurie americium-241/beryllium source. The technician believed he left the gauge at the Dallas site so he drove back to that site. The gauge was not there. The technician called his supervisor but never made contact. The technician called the company office and left a voicemail about the incident which was retrieved this morning. The licensee is notifying local law enforcement, contacting area pawn shops, and conducting its investigation. More information will be provided as it is obtained in accordance with SA-300. Texas Incident Number: 9806
The following update was received from the Agency via email: The location where the event occurred is a temporary job site in the 7400 block of Hillcrest Road in Frisco, Texas. The gauge, a Humboldt 5001 EZ, contains 10 milliCuries of cesium-137 (not 8) and 40 milliCuries of americium-241/beryllium. The insertion rod was locked. The licensee has made a report to the Frisco police department. The licensee has thoroughly searched the construction site a second time and will be checking businesses around the site for possible video surveillance that may provide information. The Agency has informed the Frisco fire department/emergency management coordinator. Further information will be provided as it is obtained in accordance with SA-300. Notified R4DO (Azua) and NMSS Events Notification, ILTAB, and CNSNS (Mexico) via email.
The following is a summary of the update received from the Agency via email: The licensee has recovered the gauge and sent it the manufacturer for calibration and testing. Additional information has been requested by the Agency. Notified R4DO (Roldan-Otero) and NMSS Events Notification, ILTAB, and CNSNS (Mexico) via 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. 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.
