Title	Leaking Source
Event Description	The following information was provided by the the Colorado Department of Health via email: On June 12, 2023, as the semi-annual leak tests/inventory were being performed at Sky Ridge Medical Center (RAML 1053-01), a leaking Co-57 Benchmark mini flood source (SN BM552021321103) was found. The exact timing of when the source started leaking is unknown. The source was last inventoried in December 2022, and was at background. [A staff member] from the Colorado Associates in Medical Physics (CAMP) found the source had 185 Bq (0.005 micro-Ci) or more removable contamination in excess of the regulatory limits. The initial removable contamination resulted in a wipe count of 3835 cpm (0.00525 micro-Ci) of removable contamination. The source was cleaned with paper towels and dish soap and when re-wiped had a lower count (1900 cpm), but remained above background even after additional wipes. All paper towels used for cleaning surveyed at background (0.03 mR/hr) and were disposed of in the hot trash in the hot lab. The source was wrapped in a thick trash bag, secured with tape and was placed in the shielded decay cabinet. The activity of the source on 6/12/2023 was 5.02 milli-Ci. The storage container, the cardiac single-photon emission computed tomography camera, and the hot lab counters were all wiped and surveyed, and all readings were at background (0.03 mR/hr). The source did not appear damaged or broken. CAMP will dispose of the source, and they have initiated a disposal inquiry. In the meantime, the source will remain in the shielded decay cabinet.
