| Title | Agreement State Report - Leaking Sealed Source |
| Event Description | The following information was obtained from the Commonwealth of Massachusetts via email:
Licensee reported one leaking sealed source (Model A3901-2, S/N P4-892, 6 mCi, Co-57) and one contaminated sealed source (Model A3901-2, S/N P4-898, 6 mCi, Co-57). These were among ten sources received from manufacturer individually wrapped in plastic ziplock bags. Leak test results for the other eight sources indicated that they were free of contamination. Leak test result for SN P4-892 was reported as 5.04 times the 0.005 microCurie wipe test limit and the leak test result for SN P4-898 was reported as 23 percent of the 0.005 microCurie limit. Leak test wipes were taken on 4/10/17 and analyzed on 4/11/17. Licensee reported the subject sources were not taken out of their respective bags and did not come into contact with anything other than the leak test swab. Initial survey of the outside of the transport package, and subsequent surveys of gloves worn during the leak testing, work area surfaces, inside the lead pig that contained the plastic bags, and outside the ten individual plastic bags indicated no other contamination present other than the interiors of the two plastic bags containing the two suspect sources and the sources themselves. P4-892 was returned to Eckert and Ziegler for analysis. P4-898 was re-wiped for analysis by licensee's leak testing consultant service. Agency [Massachusetts Radiation Control Program] considers this event docket to currently be OPEN. |
