Title	Leaking Source
Event Description	The following information was provided by the Pennsylvania Department of Environmental Protection, Bureau of Radiation Protection (the Department), via email: On November 21, 2025, the licensee was performing a routine sealed source leak test and discovered that a Cs-137 vial reference standard (model RV-137-200U, S/N 1710-68-8) was leaking. The licensee used a Capintec CRC 55tW well counter to determine if the source was leaking or contaminated. The source container was wipe-tested on the inside and found to also be contaminated. The dose calibrator dipper was very slightly contaminated and also removed from service. All other equipment associated with the source was wipe tested and found to be free of contamination. The source was immediately removed from service. The sealed source was replaced in the original lead container and placed into gloves and a plastic bag along with all associated wipes and the dose calibrator dipper. The licensee will package the material and send it for disposal. The estimated activity of the source was 170 microcuries, and the leak test results were 0.0139 microcuries. The Department will perform a reactive inspection. More information will be provided as it is received. Event report number: PA250016
