Event Notification Report for January 27, 2021

AGREEMENT STATE REPORT - LEAKING CALIBRATION SOURCE

The following information was received via E-mail:

"On 1/4/2021, a leak test was performed on an Isotope Products Laboratories Cs-137 sealed source vial, serial number 1074-19-20, used as a dose calibrator constancy source. The current calculated activity at the time of the leak test measured 147.49 microcuries from the reference date of 9/1/2004. The measured results of the leak test revealed an activity of 0.012 microcuries on 1/4/2021 at 1253 EST.

"The Cs-137 sealed source was promptly sealed within its lead container and firmly taped closed. This taped pig was then placed inside of several nitrile gloves, which were also generously taped closed, adorned with radioactive material stickers and the source was placed into the facility's radioactive material waste storage closet. The visible label includes the isotope, date of storage, current activity, and signature of the individual who stored it. The same documentation was also entered into the sealed source inventory. The RSO was then promptly notified of the event.

"The source leak test was conducted by Alliance Medical Physics."

Georgia Incident Number: 35

This material event contains a "Less than Cat 3" level of radioactive material.

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS

The following information was received via E-mail:

"The licensee's facility management group was going through their records and inventory. They discovered that six tritium exit signs at the Church in Blair, NE had been replaced with non-tritium signs in 2007. They are unable to find the documentation regarding the signs' disposal and therefore are unable to determine if they were disposed of properly. The building and storage buildings were searched and the signs were not found. Due to the lapse in time and purchase date of 10/25/1993, serial numbers were not available and no further follow-up will be conducted."

Nebraska Item Number: NE210002

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.

NON-AGREEMENT STATE REPORT - SHUTTER NOT FUNCTIONING CORRECTLY

The following is a summary of a call received from the licensee:

The licensee reported a shutter stuck open on a DMC-19 gauge, s/n: 7759LX, with a 1,000 microCi AM-241 source. The shutter is currently closed and locked. There were no overexposures. Global Gauge was working on the shutter and is expected to conduct repairs on 01/20/2021.

This material event contains a "Less than Cat 3" level of radioactive material.

AGREEMENT STATE REPORT - STOLEN MOISTURE / DENSITY GAUGES

The following information was received via E-mail:

"On 1/19/21, The California Office of Emergency Services (Cal OES) contacted the Radiologic Health Branch (RHB) to report an incident involving five stolen moisture / density gauges. The initial report to Cal OES was made by the Santa Clara Fire Department. Upon receipt of the Cal OES incident report, RHB contacted the licensee and learned the following:

"The licensee became aware of this theft on 1/19/21, when one of their staff members attempted to collect a gauge from the authorized storage unit located at 3033 Lafayette Street, Unit A133, in Santa Clara, CA. The licensee had five gauges stored at this location.

"According to the Public Storage facility personnel, the theft occurred late at night on Friday, 1/15/2021, when eight units were burglarized that day. The licensee stated that they did not receive any notification from the storage unit personnel regarding the theft on Friday. On 01/19/21, the licensee notified the Santa Clara Police Department of the theft (case number: 21-115042) and dispatchers were able to recover five transport cases near De La Cruz and Hwy 101 in Santa Clara, but the gauges were all missing.

"The gauges that were stolen include:

"1. CPN International MC-3, S/N M380709085, 50mCi of AmBe 241 and 10mCi of Cs 137
2. InstroTek MCE-3, S/N 30380, 50mCi of AmBe 241 and 10mCi of Cs 137
3. InstroTek MCE-3, S/N 30958, 50mCi of AmBe 241 and 10mCi of Cs 137
4. InstroTek Explorer 3500, S/N 3375, 44mCi of AmBe 241 and 11mCi of Cs 137
5. InstroTek Explorer 3500, S/N 3826, 44mCi of AmBe 241 and 11mCi of Cs 137

"RHB will be following up on this investigation."
