Title	Leaking Sealed Source
Event Description	The following information was provided by the Maryland Department of the Environment (MDE) via email: On February 20, 2025, an incident involving a sealed radioactive source [leaking source] at the PET/CT Department of Johns Hopkins Imaging, Bethesda was reported to the MDE. The issue was identified during a routine leak test conducted by the facility's health physics consultant, Krueger Gilbert Health Physics. The sealed vial source, Cs-137 (Serial Number 16694, activity 0.199 mCi as of March 1, 2002), was used for quality control of the Capintec CRC dose calibrator. Upon detection of the issue, the sealed source was immediately withdrawn from service, placed in a polythene zip-lock bag, and securely stored in the hot lab. A comprehensive contamination survey was conducted by collecting wipe samples from the dose calibrator, handling tools, storage container, storage area, and other relevant locations. The survey results confirmed no detectable radioactive contamination. As a precautionary measure, the licensee was instructed to maintain the sealed source in double-sealed polythene packaging within a secure container. The licensee is currently awaiting a return kit for the proper disposal of the source through an authorized agency or supplier. Upon completion of the disposal process, all relevant documentation will be submitted to MDE. MDE will provide follow up to this reactive investigation until the source is securely disposed.
