Title	Agreement State - Leaking Sealed Source
Event Description	The following was received from the Massachusetts Radiation Control Program (the Agency) via email: On December 6, 2021 at 1435 EST the Massachusetts Radiation Control Program received a call from the [Radiation Safety Officer] RSO at Amherst College reporting a leaking sealed source. The source is an open-window reference source (RM Corp, s/n R8023) containing 0.001 milliCi of Am-241 and the RSO believes he accidentally wiped the window while collecting the leak test sample of the source, the analysis of which showed 0.0908 microCi of removable activity which is in excess of regulatory limits. The RSO collected the leak test sample on November 29, 2021 at 0930 EST and sent it the same day to RSCS, Inc. for analysis. The leak test results were transmitted to the RSO by email on December 2, 2021 but the RSO was on vacation from December 2 through December 3 and was unable to review the email. The RSO was back at work on December 6, 2021 and reviewed the email at 1230 EST due to previous work commitments in the morning. The area where the source was handled was surveyed and no contamination was found. The RSO assumes the source window was damaged due to being wiped therefore the source will be secured and properly disposed of in accordance with the regulations. The Agency considers this event open. Massachusetts Event Number: TBD
