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

The following event description was received via e-mail from the Virginia Radioactive Materials Program (VRMP):

"On June 29, 2021, at 1039 EDT, a representative of the VRMP received a report from a licensee's Radiation Safety Officer (RSO) via telephone call that a portable nuclear moisture/density gauge was damaged when hit by a car at a jobsite. The report indicated that a Troxler density gauge (Model 4640-B, containing 9 milliCuries of Cesium-137) was being used for asphalt testing when a car drove into the closed lane and hit the gauge. During the accident, the gauge housing was damaged but the source appeared to remain intact within the housing. The licensee's survey of the gauge yielded readings of 0.05 mR/hr at about 3-4 feet distance from the gauge. The gauge was taken to the licensee's office in its transport container and then was sent for further evaluation and leak testing on the morning of June 30, 2021. The VRMP is working with the licensee to obtain additional information. This report will be updated once the licensee's investigation is complete and the information is received. According to the RSO, no public exposure occurred."

EN Revision Text: AGREEMENT STATE REPORT - DAMAGED SOIL MOISTURE DENSITY GAUGE

The following event report was received via e-mail from the Florida Bureau of Radiation Control (BRC):

"The vice president (VP) of the licensee called the BRC at 1015 EDT to report that a SMDG [(small moisture density gauge)] was hit or run over by a front end loader at 1010 EDT this morning. The location is a construction site north of the intersection of Connorton Blvd. and US-41 Land O' Lakes, FL 34637. The VP intends to evaluate SMDG, then send it to Troxler. The VP will provide a written report to the BRC."

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

The following report was received from the Texas Department of State Health Services (the Agency) via email:

"On June 30, 2021, the Agency was notified by the licensee's radiation safety officer (RSO) that a Troxler model 3440P was stolen from a truck parked overnight at a technician's home. The gauge contains a 40 milliCurie americium - 241 source and an 8 milliCurie cesium - 137 source. The technician had taken the gauge home on June 29, 2021. The gauge was inside a locked transport container that was located inside a locked metal container which was chained with two independent chains and locked to the back of the truck. The chains were cut and the metal container was stolen. The technician went to their truck at 0530 [CDT] hours on June 30, 2021, and discovered the theft. The technician spoke with neighbors that told him their dogs were barking at around 0230 [CDT] hours, and he suspects this may have been when the gauge was stolen. The RSO stated the operating arm was locked in the shielded position and that local law enforcement [Fort Worth Police] was notified."

Texas Incident Number: 9862


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 - STOLEN FIXED NUCLEAR GAUGE

The following report was received from the Texas Department of State Health Services (the Agency) via email:

"On June 30, 2021, the Agency was notified by one of its General License Acknowledgement holders that it had determined that a Vega model SHLD1 nuclear gauge, containing 50 milliCuries of cesium-137, was missing and suspected stolen. The gauge had been mounted at a facility [in Kosse, TX] that was closed in 2019. The gauge is thought to have been stolen at some point after the facility closed."
