EN Revision Text: AGREEMENT STATE REPRT - STOLEN TRUCK CONTAINING A MOISTURE DENSITY GAUGE

The following was reported by the Texas Department of State Health Services (the Agency) via email:

"On June 13, 2022, the licensee notified the Agency that on Friday, June 10, 2022, a truck containing a Insto Tek 3500 moisture density gauge was stolen. The gauge contained a 44 millicurie americium-241 source, and an 11 millicurie cesium-137 source. The licensee reported that the technician had stopped at a convenience store to buy some items and when they came back out the truck was missing. The licensee stated the gauge was locked in the back of the truck but was unsure if the keys to the locks were also taken. The licensee stated the gauge has an old [Global Positioning System] (GPS) tracking device that was inactive. The licensee stated they had contacted the GPS service company to see if the tracking device was still active and the gauge tracked that way. The licensee stated it would take up to 24 hours to determine if the tracking device could be used. The licensee stated the local police was notified of the theft. The individual who contacted the Agency stated they had not interviewed the technician about the event so some of the information requested by the Agency was unknown. Additional information will be provided as it is received in accordance with SA-300."

* * * UPDATE ON 2/22/2023 AT 1048 EST FROM CHRIS MOORE TO ERNEST WEST * * *

"On June 13, 2022, the licensee notified the Agency that a pickup truck with a Instro Tek 3500 moisture/density gauge had been stolen on June 10, 2022, when the technician left the truck running with the doors locked. The secured gauge in the back of the truck contained a 10 millicurie cesium-137 source and a 40 millicurie americium-241/beryllium source. The truck was recovered and was partially stripped for parts. The gauge was missing. The source was locked, however, the keys to the gauge were in the pickup truck. The licensee conducted training on security of the gauge and not leaving trucks running even if the gauge is properly secured. The company is purchasing GPS tracking units to install on the gauges. On Feb 21, 2023, the licensee reported to the Agency that the gauge was found on February 20, 2023, in the back of a stolen U-Haul truck. The licensee has the gauge in their possession and the gauge is in good condition."

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 - DOSE LIMIT EXCEEDED FOR GENERAL PUBLIC

The following information was received from the state of Arkansas via email:

"UAMS (University of Arkansas for Medical Sciences) reported to Arkansas Radiation Control Program on May 27, 2022, that three (3) persons (radiation workers), acting under verbal orders, volunteered to be injected as test subjects for the evaluation of two (2) different PET/CT scanners with F-18 FDG.

"As part of an investigation, radiation exposure calculations were performed, and results submitted for review. It has been determined that the limit for public dose as defined in 10 CFR 20.1003 and stated in RH-1208.a., was exceeded.

"Reporting Requirement: Arkansas State Board of Health Rules for Control of Sources of Ionizing Radiation RH-1504.a.2.d and 10 CFR Part 20.2203(a)(2)(iv).

"The NRC HOO was notified by email of this discovery on July 5, 2022."

* * * UPDATE ON 2/15/2023 AT 1348 EST FROM ANGELA MINDEN TO KAREN COTTON * * *

"The University of Arkansas for Medical Sciences (UAMS) reported that three radiation workers volunteered to be injected with F-18 FDG (fluorodeoxyglucose) and scanned in order to compare the image quality of an existing and a new PET/CT scanner. The events occurred between 4/13/2022 and 4/15/2022. As part of the investigation, radiation exposure calculations were performed by a contractor of the licensee, and the results were submitted for Arkansas Department of Health review. The activities of F-18 FDG received by the three physicians were 408.85 MBq (11.05 mCi), 392.2 MBq (10.6 mCi), and 403.3 (10.9 mCi). TEDEs of 24.1 mSv (2,410 mrem), 25.1 mSv (2,510 mrem), and 20.1 mSv (2,010 mrem) were received from x-ray and F-18 FDG combined, respectively. The PET-only TEDEs were 6.1 mSv (610 mrem), 5.2 mSv (520 mrem), and 6.3 mSv (630 mrem), respectively. The estimated doses exceed the limits for an individual member of the public and are therefore considered a reportable event under RH-1504.a.2.D. [10 CFR 20.2203(a)(1)(iv)]."

NMED Number: 2203303

AGREEMENT STATE REPORT - OCCUPATIONAL DOSE LIMIT EXCEEDED

The following information was provided by the Illinois Emergency Management Agency (the Agency) via email:

"The Agency received written correspondence on February 16, 2023, indicating a worker at a Romeoville, IL nuclear pharmacy (Sofie, RML IL-02074-01) received a whole body dose that exceeded the occupational limits in 32 Ill. Adm. Code 340.210. The exposure occurred over the course of 2022 and no adverse health impacts are anticipated. Specifically, the information provided indicates a quality control production associate received 5,090 millirem over the course of 2022, exceeding the occupational limit of 5,000 millirem.

"The licensee has conducted an investigation and believes the cause is related to both a management deficiency and equipment issues. New duties assigned in July of 2022 resulted in increased exposure which was apparently not reviewed and/or assessed at a frequency sufficient to limit occupational dose. Additionally, dose delivery equipment reportedly failed at some point in 2022, resulting in the use of equipment with insufficient shielding. The licensee identified corrective action as more frequent dosimetry exchange, repair of equipment (timeline unspecified) and reassignment of duties.

"This is a reportable incident under 32 Ill. Adm. Code 340.1230 and was reported to NRC the same day (2/16/23). The licensee provided timely notification. In the next week, IEMA inspectors will perform a reactionary inspection to assess the adequacy of the licensee's investigation and corrective action, compliance with Agency regulations and root cause determination."

"On 2/21/2023 at 1402 [PST] SONGS [San Onofre Nuclear Generating Station] notified San Diego Regional Water Quality Control Board (SDRWQCB) regarding the results of a quarterly monitoring report. The report indicated the 24-effluent toxicity sample resulted in a 'Fail.' The results prompted a 24 hour notification to the SDRWQCB in accordance with the NPDES [National Pollutant Discharge Elimination System] permit. There was no significant effect on the health and safety of the public or the environment.

"Action Taken: SCE [Southern California Edison] Environmental notified the SDRWQCB via telephone voice mail at 1402 on 2/21/2023 followed by an e-mail describing the reason for the notification."
