| ENS 55771 | 23 February 2022 06:00:00 | Agreement State | Leaking Sealed Source | The following information was provided by the Arkansas Department of Health (the Department) via email: The Agreement State Radioactive Materials Licensee reported to the State of Arkansas, Arkansas Department of Health, on February 23, 2022, that a general licensed device listed on their specific license has tested positive on the leak test results. The Department provided correspondence to the licensee on February 25, 2022. The leaking sealed source was Ni-63, which is used in a Agilent Gas Chromatograph. The Department considers this event to be in process and will submit additional information until this event is closed. State Event Report ID Number: AR-2022-003
The following was received via email from the Arkansas Department of Health: General License Device information: Make: Agilent Technologies Gas Chromatograph, Model 7890A, SN: CN12421187, Detector: G2397A, Source Model: E&Z NER-004P. Source Serial Number: U37072, Original Activity: 13.2 millicuries Ni-63 (May 2020), Current Activity: 13.05 millicuries Ni-63 (as of Discovery Date: January 5, 2022). U37072 Leak test result: 0.0056 microcuries of removable contamination wiped from its inlet/column adapter. Source Serial Number: U38668, Original Activity: 13.2 millicuries Ni-63 (May 2021), Current Activity: 13.14 millicuries Ni-63 (as of Discovery Date: January 5, 2022). U38668 Leak test result: 0.0495 microcuries of removable contamination wiped from its inlet/column adapter. Immediate corrective actions were performed by the Agreement State Radioactive Materials Licensee, as described in Arkansas State Board of Health Rules for Control of Sources of Ionizing Radiation RH-402.c.5. Corrective actions included immediately suspending operations of device, device was tagged-out and taped shut, and properly posted. Proper wipes and surveys were performed indicating no detectable activity. The manufacturer was contacted by the licensee. The sealed sources were transferred to the manufacturer on March 15, 2022. The Agreement State Radioactive Materials Licensee noted that there were no unusual occurrences. The required thirty-day report has been received by the Agreement State Radioactive Materials Licensee. There have been no known radiation exposures to any worker(s) and/or member(s) of the public. The Arkansas Department of Health did not issue any Items of Noncompliance. The Arkansas Department of Health considers this incident closed and will review this information during the next routine inspection.

| ENS 54402 | 19 November 2019 22:00:00 | Agreement State | 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). |
