Event Text

The following summary was provided by the licensee via phone:

On May 4, 2023 at 1145 EDT, the licensee found contact dose rates of 215 and 555 millirem-per-hour at 2 separate spots on the top of an exclusive use package during receipt survey. These dose rates are above the 200 millirem-per-hour allowable. No loose surface contamination was identified. The package contains tools from Holtec and was intact on delivery. The package has subsequently been secured in a locked radiation storage building. No overexposure or unauthorized exposure resulted to plant personnel. The licensee suspects shielding, internal to the package, may have shifted and the licensee will investigate further. Dose rates at one foot from the package were recorded at 65 millirem per hour.

The following information was received from the New York State Department of Health (NYSDOH) via email:

"The New York State Department of Health conducted a routine inspection of lnficon, Inc. on May 5, 2023, and were made aware of Ni-63 (2.4 mCi) source that exceeded the 0.005 microcurie leak testing threshold and is considered leaking. Information on the source is below:

Make: NRD, LLC
Model: N1001 (SSDR: NY-0502-S-103-U)
Serial Number: INF739
Date of Sample Collection: 4/27/2023
Leak Test Result: 1.82E-2 microcuries
Analysis Report Date: 5/2/2023

"In accordance with lnficon's license, this source was obtained for secondary manufacturing and assembly into Micro Argon Ionization Detector (MAID) cells. lnficon detected this leaking source immediately following assembly prior to distribution in accordance with all regulatory requirements and the conditions of their license. Once it was determined that this source was leaking, personnel were notified, and the device was immediately quarantined. lnficon conducted removable contamination surveys around the device in question, however, they do not believe that any personnel or equipment may have been contaminated from this leaking source. Wipe test results are pending to date. As this is the second leaking source reported by lnficon (See NY-23-01 notification for the first leaking source notification), lnficon has hired an external consultant to review and audit their assembly process. This audit has been scheduled and lnficon has agreed to submit the findings of this audit to New York State Department of Health.

"Following the results of these wipe tests, the facility plans to dispose of this source and equipment. New York State Department of Health is in continued discussion with lnficon regarding next steps for this event.

"No further information on the device, source or incident is available at this time. Any updates to this event will be provided as soon as feasible. This incident is tracked under Incident No. 1436 by NYSDOH.
