EN Revision Text: AGREEMENT STATE REPORT - LOST EXIT SIGNS
The following is a summary of information received from the Colorado Department of Public Health and Environment via email:
Four exit signs, each containing 12.57 curies of tritium (50.28 curies total), were determined to be lost by the licensee.
Manufacturer: Isolite Corporation
Model Number: SLX60
Colorado event number: CO240025
* * * UPDATE ON 01/21/2025 AT 1458 EST FROM KATHRYN KIRK TO KERBY SCALES * * *
The following update was submitted by the Colorado Department of Public Health and Environment via email:
The four exit signs initially reported as lost have been found.
Notified R4DO (Deese), NMSS Events Notifications (email), ILTAB (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.

AGREEMENT STATE REPORT - STOLEN DENSITY GAUGE
The following information was provided by the New York State Department of Health (NYSDOH) via phone and email:
"The New York State Department of Health was notified by the New York State Office of Emergency Management at 0230 EDT that Materials Testing Laboratories called to report a stolen Troxler Model 4640 surface thin layer density gauge (serial number 1289) containing 10 mCi of Cs-137.
"The gauge was stolen at 572 11th Ave between 43rd and 44th Streets in Manhattan at 2130 EDT on 10/23/24. NYPD were immediately notified and a report was filed.
"The gauge recently had a tracking device affixed. They are not seeing any 'pings' on the device location probably because it is out of WIFI range and not moving. They are actively monitoring for movement and location information."
NY Event Number: TBD
* * * UPDATE ON 10/25/2024 AT 0137 FROM NATHANIEL KISHBAUGH TO BILL NYTKO * * *
The following information was provided by the New York State Department of Health (NYSDOH) via email:
"At approximately 0230 EDT, on October 24, 2024, New York State Department of Health Bureau of Environmental Radiation Protection (NYSDOH BERP) was notified by New York State Office of Emergency Management (NYS OEM) that the radiation safety officer (RSO) of Materials Testing Laboratories reported a stolen Troxler Model 4640 Serial number 1289, surface thin layer density gauge. The RSO reported that [the source activity] was 10 millicurie (mCi) of cesium-137 (Cs-137). According to the United States Nuclear Regulatory Commission Sealed Source and Device registry the source activity is 9 mCi of Cs-137. Based on information provided, it appears that the actual activity of the Cs-137 source was approximately 9 mCi.
[Information stated in original message]
"At 1229 EDT, on October 24, 2024, NYSDOH BERP called the RSO. The RSO said the employee was working on 11th street and the road was blocked off due to repaving. The gauge was on a hand truck to facilitate multiple surveys at various areas along, approximately, a several mile distance. At the time of the suspected theft, the employee was closer to the east side of the road, set up the gauge, walked 100 feet to take a measurement, and when the employee turned around the gauge was gone. The employee searched the area for 20 minutes and then called the RSO. The RSO then instructed the employee to call the police. Since the incident the RSO and staff have been surveying a 30-block area, posting flyers, and [made multiple] attempts to use the tracking device program.
"At 1340 EDT, on October 24, 2024, NYSDOH BERP called RSO for additional clarification and assessment as the original report failed to mention whether the device was stolen with the source in an unshielded or shielded position. Additional discussion indicated that the gauge was about to be in use, but was in the source in locked position. Allegedly, by the RSO, the authorized user of the device, turned to walk 100 feet to mark the next measurement location, and then completed paperwork. Thereby suggesting that the device was in a shielded position when stolen.
"Please note that this is a formal follow up to the email sent by NYSDOH sent at 0350 EDT, on October 24, 2024.
"NYSDOH is closely monitoring this event and has assigned NYSDOH Incident No. 1504 to continue monitoring this event."
Notified R1DO (Dentel), NMSS Events Notification (email), and ILTAB (email)
* * * UPDATE ON 10/29/2024 AT 0917 EDT FROM NATHANIEL KISHBAUGH TO BILL NYTKO * * *
The following information was provided by the New York State Department of Health (NYSDOH) via email:
"On October 25, 2024, NYSDOH received an email from the RSO stating that they has retrieved the stolen density gauge from an individual that found the device. Prior to use, the RSO stated that they will perform a leak test and send the gauge to a licensed repairer/servicer for visual and operational inspection of the device.
"The NYSDOH acknowledged the updated information from the RSO and is still requesting a final report of the incident. This final report will include steps to prevent recurrence."

AGREEMENT STATE REPORT - LOST RADIOACTIVE LIQUID
The following information was received from the Illinois Emergency Management Agency (the Agency) via email.
"The Agency was contacted on 10/23/24, to advise of the loss of a syringe containing 7.5 mCi of liquid Tb-161. The loss occurred at Siemens Medical Solutions (RML #1130-02) in Hoffman Estates, IL. Reportedly, the week of 10/16/24, a [Siemens Medical Solutions] technician placed the syringe inside a blue syringe shield for future testing. On Friday, 10/18/24, the supplier of the syringe shields (Hot Shots NM, LLC) conducted a routine collection of used shields. Despite it being properly labeled, it is suspected that Hot Shots' courier collected the syringe shield containing the Tb-161. After the investigation, it is believed the syringe was transported back to the Hot Shots' Loves Park, IL, facility where it was discarded into their Tc-99m decay-in-storage bin.
"There was no indication of attempted theft or diversion."

EN Revision Text: AGREEMENT STATE REPORT - LOST SOURCE
The following information was provided by the Illinois Emergency Management Agency (the Agency) via phone and email:
"On January 8, 2025, the Agency was notified by representatives of the Lincoln Memorial Hospital of two sources that were missing after being offered for shipment through a common carrier. The two sealed Co-57 calibration sources collectively accounted for approximately 0.5 millicuries. While the sources were offered for shipment on October 23, 2024, the fact the sources never reached their destination was not discovered until an audit on January 8, 2025. After having received no further information from the carrier, the package is being declared as lost. The Agency staff will evaluate the timeliness in reporting, the level of accountability exerted over the sources, and root cause for the loss in a reactive inspection this coming week. Updates will be provided as they become available."
