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

The following information was provided by the New York State Department of Health Bureau of Environmental Radiation Protection (NYSDOH BERP) via fax:

"On November 3, 2022, at approximately 1430 EDT, an authorized user for the licensee had finished conducting soils testing at a temporary job site located in Manhasset, NY and locked the moisture density device in the carrying case within the trunk of their vehicle. The authorized user was conducting concrete work while the gauge was locked in the trunk and returned to their vehicle later to find that the vehicle was stolen, with the gauge locked in the trunk. The authorized user contacted the Radiation Safety Officer (RSO) and Nassau Police immediately and the case was initiated by Nassau [Police] to track this vehicle. The RSO contacted NYSDOH BERP the following morning to report the missing device.

"The following information is available on this device: Make/Model: Troxler 3430 Source 1: Cs-137 (10 millicurie); Source 2: Americium-241:Be (40 millicurie); Device S/N: 20136.

"New York State Department of Health is reaching out to the manufacturer and neighboring regulators to inform them of this event. NYSDOH will continue to monitor this event and provide updates as necessary.

The following information was provided by the NYSDOH BERP via fax:

"On November 21, 2022, the licensee notified the NYSDOH BERP that the above mentioned vehicle and device were located by local law enforcement agencies and returned to the licensee. The licensee confirmed that there was no apparent tampering of the device and carrying case, however, the licensee is performing a leak test to confirm sources have not been breached during this incident prior to recommissioning this device into service.

"The licensee is providing a written description of this event including a failure analysis and proposed corrective actions. As a result, NYSDOH will continue to monitor this event and provide updates as necessary. This event is still open as of 11/21/2022."

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.

LOST/RECOVERED RADIOACTIVE SOURCE

The following is a synopsis of information provided by XCEL NDT (the Licensee) via phone call in accordance with Headquarters Operations Officers Report Guidance:

On November 14, 2022, the licensee's corporate Radiation Safety Officer (RSO) received a report of the theft (loss of control) and subsequent recovery of a vehicle that contained a locked and shielded Ir-192 sealed source. The 52.3 Curie Ir-192 sealed source is from an Industrial Radiography Camera. No damage to the source was indicated.

The vehicle was stolen at 0710 MST on November 14, 2022 in Billings, MT and was recovered later the same day at 1023 MST. The RSO was immediately notified. The RSO immediately notified local law enforcement. There is an ongoing police investigation.

THIS MATERIAL EVENT CONTAINS A 'Category 2' LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

AGREEMENT STATE REPORT - DAMAGED GAUGE

The following information was provided by the State of Ohio via email:

"The Ohio Department of Health (ODH) received a call on November 14, 2022, concerning a Troxler model 3241-C gauge [100 mCi Am-Be source], that was damaged in a fire at a job site in Wellston (Jackson County). The gauge was stored in a trailer at a temporary asphalt plant. The plant closed last week for the winter and the gauge was going to be removed this week. The fire destroyed the trailer and melted the plastic outer shell of the device. An ODH inspector responded to the site. The source was located under the remains of the trailer but is buried in the ashes from the trailer. The highest dose rate detected was 7mR/hr which indicates that the source is shielded by the lead in the device. A licensed service provider will be on site on November 15, 2022, to retrieve the source and transport it for disposal. The licensee will provide security at the site until the source is removed."
