EN Revision Text: AGREEMENT STATE REPORT - STUCK SHUTTER
The following information was provided by the Pennsylvania Bureau of Radiation Protection (the Department) via email:
"On July 22, 2026, the licensee notified the Department of a shutter failure that was discovered on July 21, 2026.
"On July 21, 2026, the licensee discovered that a fixed gauge shutter was stuck open. The gauge is a Global Gauge Corporation (formerly E.S.C. Resources, Inc.) model SH-6000, serial number 70705 containing 2 Ci of Am-241. The gauge access area has been shut down. The licensee contacted a service provider and Global Gauge Corporation.
"The Department will perform a reactive inspection."

* * * UPDATE ON 08/07/2026 AT 0802 EDT FROM JOHN CHIPPO TO ERNEST WEST * * *
"Global Gauge Corporation responded to troubleshoot the device and completed repairs on July 28, 2026. The cause of the shutter failure was determined to be a failed solenoid switch. The defective solenoid switch was replaced, and the shutter was tested and verified to be functioning properly before the gauge was returned to service on July 28, 2026.
"Radiation surveys confirmed that radiation levels in accessible areas remained within expected limits, no personnel exposures occurred, and access controls remained in place until repairs were completed, and proper shutter operation was verified.

AGREEMENT STATE REPORT - MEDICAL EVENT
The following information was provided by the New Jersey department of environmental protection (NJ DEP) via email:
On July 29, 2026, at the Robert Wood Johnson University Hospital in New Brunswick, New Jersey, the licensee was administering a Y-90 SIR-Sphere therapy of 63.45 mCi to a patient. During the procedure, the patient unexpectedly coughed, which caused the treatment catheter to move away from the treatment site. The intended dosage was 63.45 mCi, but the administered dosage was 25.55 mCi to the intended site (the liver) and 37.9 mCi to the wrong site (a different part of the liver). The incident is being managed by the radiation safety officer.
NJ event number: TBD
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.
