| ENS 56242 | 28 November 2022 12:30:00 | Agreement State | Stolen Moisture Density Guages | The following information was provided by the Colorado Department of Public Health and Environment (the Department) via email: At approximately 0715 MST on November 28, 2022, the Department was contacted by the (Company Radiation Safety Officer) CRSO of Kleinfelder, Inc. (CO 958-01) to inform the Department that two Troxler 3430 (SN 35349 & SN 35335) moisture density gauges were discovered to be stolen from their temporary job site. Each gauge had sealed sources containing not more than 9 mCi of Cs-137 and 44 mCi of Am-241:Be or 66 micro curies of Cf-252. An authorized user arrived at the temporary job site around 0530 MST to pick up supplies when they noticed the door to the container express (conex) box was open. Upon further investigation, it was discovered that both gauges were missing. The site was secured by a security fence and under video surveillance, and that footage is currently under review. The thieves broke the exterior lock to the conex box door and they broke a lock to a job box in the conex box that contained both gauges in their locked transport cases. The job box was also bolted to the ground but those bolts were left intact. The CRSO estimates that the gauges were last seen/used on November 23rd or 24th, but the date of the theft is unclear at this time. Additionally, multiple other contracted companies were targeted in this theft that presumably occurred during the Thanksgiving holiday weekend. Colorado Event Report ID No.: CO220040 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 42649 | 15 June 2006 07:00:00 | Agreement State | Agreement State Report - Damaged Moisture Density Gauge | The State provided the following information via email: A Troxler 3440 portable gauge serial number 37319 (8 millicuries Cs-137, 40 millicuries Am-241:Be) was damaged when a large earth moving piece of equipment backed over it. The operator was taking density readings about 20 feet behind the equipment when the equipment backed up. The operator ran to safety as the gauge was struck. The operator roped off a 50 foot radius around the gauge and called the RSO. When the RSO arrived at the site, the RSO and the operator took the buried gauge out of the soil and inspected it. The fire department was called and took readings in the area with a Geiger count-rate meter. Radiation levels were determined to be in the normal range. The top outer portion of the gauge was damaged and the source rod bent slightly, but the source areas were intact. The source rod was put back into the gauge by pounding the handle up with a mallet. The gauge was transported back to the licensed storage location and will be sent back to the manufacture for repair or disposal. Location of Event: SeaTac Airport, Port of Seattle, City of SeaTac.

| ENS 42543 | 1 May 2006 14:30:00 | Agreement State | Agreement State - Stolen Moisture Density Gauge | The State provided the following information via email: The licensee notified (the State of Washington) office via (the) agency hotline phone number at 8:00 a.m. Monday, May 1, 2006 of a theft of a Troxler model 3430 portable moisture/density gauge (Serial Number 27641; 8mCi of Cs-137 and 40 mCi of Am-241/Be). The theft occurred sometime between Friday (p.m.) April 28, 2006 and Monday (a.m.) May 1, 2006 from a temporary jobsite trailer located at the Wal-Mart construction site on 7110 Bridgeport Way, Lakewood, Washington. The gauge was last seen Friday, April 28, 2006 when the gauge was secured in the jobsite trailer by the licensee's gauge user. The Licensee indicated that the gauge operator employed by the licensee arrived at the job-site and found the padlock on the outside of the trailer had been cut. Once in side, he found the chains securing the gauge case had also been cut and the gauge was missing. Nothing else appeared to be missing from the trailer. The gauge user was not present at the jobsite over the weekend and the licensee can not determine the exact day or time it was stolen. A police report was filed with the Lakewood Police Department and given report number 061210259."
