EN Revision Text: AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following information was received from the state of Texas (the Agency) via email:

"On August 18, 2021, the Agency was notified by the licensee that a Troxler model 3430 moisture density gauge was stolen from the back of an employee's truck. The employee's truck was parked at their apartment overnight. The licensee stated that the apartment complex security camera system showed the theft occurred at about 0149 CDT on August 18, 2021. The gauge contains a 40 milliCurie Americium - 241 source and an 8 milliCurie Cesium - 137 source. The licensee stated the gauge was locked using chains in the back of the pickup truck. The licensee reported local law enforcement has been notified of the theft. The Agency requested additional information from the licensee. Additional information will be provided in accordance with SA-300."

TX Incident #: 9877

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.

EN Revision Text: AGREEMENT STATE REPORT - STUCK OPEN GAUGE SHUTTER

The following information was obtained from the state of Iowa via email:

"On August 18, 2021, at approximately 1000 CDT, the DAV-015 #4 shutter was reported to be stuck in the open position. A survey meter measured a background level of 0.02 mR/hr outside of the gauge house, and 0.05 mR/hr inside the gauge house at that time. Locks were changed to the gauge house to prevent entry. The service company, SenTek, was notified and requested to provide service. They are expected to arrive on August 19, 2021, to provide service and repairs. This event will be updated after the service company determines the cause of the failure and the licensee provides a corrective action plan."

The gauge was manufactured by Isotope Measuring Systems, Inc., model number 5221-02, serial number 2332-2336L, and contains 5 Curies of Am-241.

NMED Number: IA210003

* * * UPDATE ON 9/2/21 AT 1522 EDT FROM RANDAL DAHLIN TO JOANNA BRIDGE * * *

The following information was obtained from the state of Iowa via email:

"The SenTek service technician arrived onsite late afternoon on August 18, 2021 and determined that the bolts holding the shutter had sheared and needed to be replaced. All other shutter bolts were inspected and found to be satisfactory. As a corrective action, the licensee is implementing an annual preventative maintenance check to inspect and replace the bolts on all shutters. The licensee's intent is to replace these fixed gauging devices with x-ray tube devices."

The State considers this event closed.
