EN Revision Text: AGREEMENT STATE REPORT - LEAKING SEALED SOURCE
The following was received from the Maine Radiation Control Program via fax:
At 0857 [EST on November 15, 2019,] NETCo, Inc. notified the state of Maine Radiation Control
Progam [the State] that they had received leak test results from their vendor [Radiation Safety & Control Services] RSCS. One the test results indicated the Ni-63 source in a replacement component to a SAFRAN Morpho Detection Trace device was leaking. Two additional tests on components with Ni-63 sources reported detectable activity but less than 0.0005 microCi. The source contains 10.0 mCi of Ni-63 and the leak test result was 0.1968 microCi on the leaking source.
The RSO at NETCo has surveyed the work area where the leak tests were
performed along with the storage container and bag that they arrived in.
No detectable activity was found. NETCo will be also performing smear tests of all the areas that came in contact with the sources. The sources (components) in question will be put in a one gallon paint can awaiting proper disposal in our locked cabinet.
The State has sent an inspector to perform additional surveys. Licensee will be providing a full report to the State as information becomes available.
