| ENS 55465 | 15 September 2021 15:17:00 | The following information was received from the state of Arkansas (the Department) via email: The Department received notification on June 16, 2021, from licensee 3D Imaging Drug Design and Development, 3DI, that a package containing 87 milliCi of Zr-89 did not reach its shipping destination. Upon review of the event, the Licensee transferred the package via (common carrier) pick-up from its Little Rock, Arkansas campus on Saturday June 12, 2021, with a scheduled delivery date of June 14, 2021. The package destination was: Memorial Sloan Kettering 1275 York Avenue New York City, New York On June 16, 2021, the package was reported missing to the Department and the activity of the package was estimated to be approximately 30 milliCi based on the 3.2 day half-life of Zr-89. The licensee had contacted the (common carrier) and the (common carrier) stated that they were unable to locate the package. Department inspectors visited the 3DI campus on June 18, 2021 and questioned the Licensee about the lost package. At that time, and currently, the (common carrier) has been unable to locate the package. The Department has spoken with multiple individuals associated with the (common carrier), both at the Little Rock location and with the companies Dangerous Goods Administration Department, about the lost package. The Department has also followed up with 3DI. The associates at the (common carrier) were able to confirm that the package was received and scanned. After acceptance, and the initial scan of the package, there are no other scans available to determine what has happened to the package. 3DI stated that the company has experienced additional shipping problems since the lost package. 3DI has had additional packages that have been scanned and shipped to Licensees other than the intended recipient. All additional packages have been able to be located and recovered or reach their final destination successfully. The initial package of Zr-89 remains missing. The Department has requested and is awaiting the 30 Day report from 3DI as required. The Department considers this incident open pending location of the missing package and will update this report as information is received. AR incident no.: AR-2021-007 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 55064 | 12 January 2021 12:24:00 | The following was received from the Arkansas Department of Health (the Department) via email: The Department received notification on January 12, 2021, from licensee Mid-Continent Laboratories, Inc., that a Troxler gauge model 3411-B ((S/N: 4794; Activity: Am-241 (44 mCi); Cs-137(9 mCi))) had been stolen from a licensee while at his residence. Upon review of the event, the Authorized User checked the portable gauge out of its permanent storage location at approximately 0600 CST to travel to Colorado for work. Before leaving, the Authorized User returned to his place of residence. While at his residence the chains securing the gauge to the truck were cut and the portable gauge was stolen from the vehicle. This event has been reported to Law Enforcement, in addition, Arkansas Department of Health inspectors are currently working with the Tennessee Department of Environment and Conservation, Division of Radiological Health, to investigate and report. (West Memphis, AR is on the border with Tennessee.) Arkansas Department of Health will be issuing a Press Release. The Arkansas Department of Health considers this investigation open pending receipt and review of any further information that may become available. Arkansas Event Report ID No.: AR-2021-001
The following update was received from the Department via email: The Authorized User was allowed to store the gauge overnight in his vehicle at his place of residence. The theft occurred between 2130 CST, January 11, 2021 and 0730 CST, January 12, 2021. The Authorized User noticed the disappearance of the gauge while leaving his residence to go to work. Notified R4DO (O'Keefe) and NMSS Events Notification and ILTAB via email.

| ENS 54402 | 21 November 2019 14:53:00 | EN Revision Imported Date : 1/17/2020 AGREEMENT STATE REPORT - DENSITY GAUGE DAMAGED The following was received from the State of Arkansas via email: The (Arkansas) Department (of Health) received notification on November 20, 2019, from licensee Professional Services Industries, Inc., that a Troxler gauge model 3430 had been struck by a skid-steer while performing routine measurements at a road construction site. The gauge was not being used at the time it was struck and the sources were in the shielded position. Upon review of the event, it was noted that the technician quickly created a thirty foot containment barrier and notified his company's Radiation Safety Officer (RSO). The RSO for Professional Services Industries mobilized to the event location. Once onsite, the RSO surveyed the immediate area around the damaged gauge and the gauge itself. The RSO determined that no radiation measurements were found to be above normal levels for that model of portable gauge. A leak test of the sealed sources was immediately conducted and the remnants of the gauge were collected and returned to the permanent storage location on November 19, 2019. The RSO and the Authorized User operating the portable gauge were wearing dosimetry. The Arkansas Department of Health considers this investigation open pending receipt and review of the licensee's 30 day report. Arkansas Event No.: AR-2019-005
The following was received from the Arkansas Department of Health via email: Upon review of the licensees 30 Day Report, received December 26, 2019, it was noted that the dosimetry badges worn by the Authorized User and RSO during the retrieval and transportation of the sources showed no measurable dose. The dosimetry badges worn were issued to the users on October 15, 2019 and the event occurred on November 19, 2019. The report contained leak test results for the sources taken immediately following the event, November 19, 2019. The results for the leak tests in both instances were measured to be below 185 Bq (0.001microCi), considering the sources to be non-leaking sources. The company conducted mandatory safety meetings with all staff in the PSI-Sherwood office who work with the portable gauges as a result of the event. Topics discussed during the meetings and e-mail included radiation safety, gauge security, and gauge control. The company also has re-trained the individual authorized user responsible for the gauge during the event via a 're-entrance' exam. The radioactive sources and associated nuclear gauge remnants were returned to the manufacturer for disposal. The sources are now listed under North Carolina Radioactive Materials License #032-0182-1. The (Arkansas) Department (of Health) considers this event to be closed, providing that no new information is received. Notified the R4DO (Young) and the NMSS Events Notification group (email). |
