EN Revision Text: AGREEMENT STATE REPORT - DELIVERED SOURCE NOT SECURED

The following licensee provided information was forwarded from the Mississippi State Department of Health via email:

"A replacement Ir-192 source [(100 Ci)] was ordered from QSA Global on 3-24-22. QSA sent an `Advanced Shipping Notice' email after hours at 1800 CDT on 5-26-22. The source arrived the following day, Friday, 5-27-22. The source was delivered to the Shipping/Receiving dock (building 9145), operated by S3 [(Syncom Space Services)]. (Note: the standard practice is for the source to be delivered directly to the building where S3 licensed sources are secured.) The Receiving worker signed for the shipment at 1000 CDT on 5-27-22. The Receiving worker is not a radiation safety qualified employee. The RSO [(Radiation Safety Officer)], nor any other radiation safety qualified personnel were contacted upon delivery of source. The RSO was not at work on Friday, and unaware the source was being delivered that day. The source was in the Shipping/Receiving building (locked when personnel are not on site) until Tuesday morning, 5-31-22. Upon arrival to work at 0600 CDT Tuesday morning, the RSO read the email from QSA Global and checked the tracking information. At that time, he realized the source had been delivered. The RSO identified which Receiving worker signed for the source. Their shift starts at 0700 CDT. Upon their arrival, the RSO verified that the source was at the Shipping/Receiving building. The RSO immediately picked up the source and brought it to the secure vault. Management was then notified, and the investigation began.

The S3 Heath Physics Coordinator and RSO (with concurrence from NASA HP [(Health Physicist)]) concluded that no employee was exposed to an unallowable amount of radiation based on where the source was placed and its proximity to employees in the area. The investigation is ongoing to identify the process failures that lead to this incident. NASA has been notified and the incident has been entered into a formal tracking system."

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following was received from the California Department of Public Health via email:

"On May 31, 2022, the RSO of Alta California Geotechnical, Inc. (Alta), contacted the Brea office of the California Department of Public Health to report a stolen moisture density gauge. The gauge was a CPN model MC-3 S/N M3811862 (10 mCi Cs-137, 50 mCi Am-241:Be). On May 27, at approximately 1700 PDT, the gauge was placed in a locked Mobile Mini (temporary storage) container in a fenced (also locked) area of the construction site in Jurupa Valley, California. The theft occurred sometime between Friday, May 27 and Tuesday, May 31. When Alta personnel arrived at the construction site at approximately 0500 PDT Tuesday morning, they discovered that the storage container lock (a hidden shank/"hockey puck" style) was drilled through and the locked transportation case containing the gauge was removed, along with other equipment. Alta personnel searched the surrounding area until approximately 0630 PDT and then contacted the Riverside County Sheriff to report the theft. The licensee's investigation into this event is ongoing and will be reviewed further by the California Department of Public Health."

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.
