EN Revision Text: AGREEMENT STATE REPORT - RADIOACTIVE GAUGE DISCOVERED IN SCRAP METAL
The following information was received from the Ohio Department of Health Bureau (ODH) of Environmental Health and Radiation Protection via email:
"On 3/30/22, ODH received notification of a load that tripped radiation detectors at a scrap facility in Marion, Ohio. The load returned to point of origin in Columbus, Ohio under DOT SP OH-OH-22-014. The Originator contacted ODH on 4/4/22 to report that they had surveyed the load and isolated a device that was box shaped, perhaps 8x4x4 inches. The item reportedly pegged the facility's Ludlum 19 (5 mR/hr), and was secured in a quarantine area.
"ODH staff responded to site on 4/5/22 and identified a Ronan Engineering Model RLL-1 gauge containing a 0.27 mCi Cs-137 source with a reading of 750 microR/hr on the side of the gauge. No contamination was detected. The facility will keep the device secure while disposal options are arranged. ODH will contact the manufacturer (Ronan Engineering) to attempt to identify the owner based on mode; and serial number on the device."
Ohio item number: OH220005
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.

EN Revision Text: AGREEMENT STATE REPORT - MEDICAL EVENT, EXCEEDED PRESCRIBED DOSE
The following was received from the State of Nevada via email:
"The patient was prescribed ten [High Dose Rate Brachytherapy] treatments [with a 9.0 curie Ir-192 source]. After four treatments, it was discovered that some of the catheters had been incorrectly labeled. This altered the dose distribution resulting in a higher skin dose than anticipated, however the target dose difference did NOT exceed 50 percent from the prescription. The remainder of the patient's treatment was re-planned to compensate for the dose already given. The total doses once complete will be within limits for the skin and the target dose will be within 20 percent of the prescription. All treatments were to the correct patient and correct site.
"The treatment area for this patient is adjacent to the skin, so the intended prescription would have given a skin max dose of nearly 100 percent of the prescribed treatment dose.
"For the four treatments given with the incorrectly labeled catheters, the dose to skin is estimated to be 3 times the initially expected dose, exceeding 50 rem.
"However, the patient's treatment was re-planned to provide additional skin sparing for the remaining treatments while maintaining minimum target coverage to compensate for the dose already given. We estimate the total skin dose from the entire treatment will exceed the initially anticipated skin dose by 41 percent. This total skin dose is still within standard protocol limits, and the written directive has been updated to be inclusive of the initial and new treatment plans and organ at risk (OAR) doses.
"The patient and referring physician were notified the day the event was discovered before the determination that a medical event took place."

"Commercially dedicated Eaton Freedom Series NEMA Size 1 and 2 full voltage reversing (FVR) contactors with mechanical interlocks that were manufactured between April 2014 until June 2018.
"The [FVRs] are designed and qualified to open and close on demand. The FVR contactors sporadically failed to electrically close on demand because the mechanical interlock is not returning to the de-energized position.
"Westinghouse sold LaSalle County Station Units 1 and 2 a quantity of 206 safety related FVR contactors that are potentially affected between 2014 and 2022.
"Westinghouse developed an alignment tool intended to increase the effectiveness of the installed mechanical interlocks and prevent them from binding. Westinghouse provided the alignment tool and associated procedure to LaSalle on February 17, 2022.
"Effective March 11, 2022, Westinghouse updated the commercial dedication instruction to include additional critical characteristics of the mechanical interlock assembly based on the results of the causal analysis. It was determined that the pawl contained within the mechanical interlock assembly was the cause of the mechanical binding.
"Westinghouse purchased the latest revision mechanical interlocks that contain Revision 3 pawls from Eaton. They are being dedicated by Westinghouse and installed by LaSalle Station in conjunction with the alignment tool, as they become available.
"Westinghouse has been in daily communication with LaSalle Station since January 2022 and provides real-time updates on the Westinghouse testing efforts.
"Westinghouse provided an on-site expert to LaSalle between February 23-25, 2022.
"The overall failure rate of the installed components has been low and is related to a tolerance stack-up among the mechanical interlock, mechanical interlock pawl, and the two reversing contactors. Additionally, the failures only occur after some time in service which cannot be correlated to a specific installed time or number of cycles. It is a random event.
"Westinghouse analyzed, reviewed, and regression tested mechanical interlocks that contain the Revision 3 pawls to confirm they are functional and meet the LaSalle environmental requirements."

The following was received from the Commonwealth of Pennsylvania (the department or DEP) via email:
"On April 7, 2022, the licensee informed the department that a Troxler Model 3440 nuclear density gauge, serial number 31109, containing 8 milliCuries of cesium-137 and 40 milliCuries of americium-241 had been stolen. The gauge was secured in the back of the technician's vehicle at his residence. The technician was leaving his residence this morning around 0800 EDT and the vehicle was missing with the gauge inside. The incident was reported to the Philadelphia Police Department and they have yet to respond to the situation.
"The DEP will update this event as soon as more information is provided."

The following was received from the State of Georgia, via email:
"Graphic Packaging International called us this afternoon to report a missing gauge. The gauge is a Berthold Model LB7441 S/N 2212 and is believed to be about 41 milliCuries. It is unknown to us at this time if the source is Cobalt-60 or Cesium-137. The last leak test was conducted on December 13, 2021. The licensee says that the gauge was installed on a part of the line that they haven't used in a long time. The Radioactivity Safety Officer (RSO) went to that part of the line to clean the tags and discovered that entire end of the line was gone. They have been having demolition work done, so it is his belief that the gauge was in the demolition. The demolition company is Grey Wolf. We are following up with the licensee and the company for more information and will keep you informed."

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.

EN Revision Text: AGREEMENT STATE REPORT - OVERDOSE TO PATIENT
The following was received from the State of California, Department of Public Health (RHB), via email:
"On April 6, 2022, Loma Linda University Health's (LLUH) Radiation Safety Officer was notified by a medical authorized user that a reportable medical event had occurred during a Y-90 Therasphere patient brachytherapy treatment on April 5, 2022.
"There were two patients scheduled for brachytherapy on the same day. Patient 1 had two tailored dose vials of Y-90 and Patient 2 had three tailored dose vials of Y-90 stored in the hot lab. A certified nuclear medical technologist mistakenly selected one of Patient 2's vials for Patient 1's treatment. The selected vial contained 4.0 GBq (108 milliCuries) with calibration date April 3, 2022 at 1200 PDT. It contained approximately 58.6 milliCuries at the time of administration.
"The two vials were taken to the therapy suite, where they were approved and used by the authorized user. The authorized user's written directive for Patient 1's liver segments 2 and 3 was to deliver a dose of 120 Gy. However, the mistake resulted in a dose of 750 Gy to the two liver segments. If the proper vial had been selected, the administered activity would have been 9.6 milliCuries.
"The error also resulted in the cancellation of Patient 2's treatment, as the Y-90 dose was no longer available. LLUH will be submitting a 15-day report to RHB. Abnormal Occurrence criteria for Medical Event's: Unplanned dose greater than or equal to 1000 rad to any other organ AND dose is greater than 150 percent of the prescribed dose."
California Event Number: 040622
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
