| Title | Agreement State Report - Leaking Kr-85 Source During Transfer to Approved Shipping Container |
| Event Description | The following report was received from the Louisiana Department of Environmental Quality via email:
On the 3rd of November, 2016, QSA Global, Inc. had an incident during the transfer of Kr-85 sources to approved shipping containers for transportation to Qual-X, Inc. for recycling. The work was being preformed at approximately 1530 to 1600 hrs. [CST]. After the completion of the work, there was no indication at that time of any possible leakage. At approximately 1800 hrs., it was noticed that the scintillation counter background had a slightly higher than normal background reading. It was determined that the only possible cause was the Kr-85 sources, as that is all that QSA Global, Inc. had worked with that day. A visual inspection of the possible leaking Kr-85 sources was performed. There was no damage to any of the windows, but QSA Global, Inc. now knows that was the point of origin of the contamination due to the surveys of the lead container that they were stored in. The sources were sealed in a 10 gallon steel drum and then placed in a plastic bag to prevent any additional release of material. The sources involved are LFE Model S-70A s/n 9234 at 168 mCi, 9332 at 184 mCi and 9333 at 184 mCi. The original activity of these sources was 1200 mCi. The building was ventilated using fans to remove the Kr-85 that had accumulated in the building. The building was surveyed at 0230 hrs. [on November 4, 2016] with no contamination detected. Another survey of the building was performed again at 0530 again with no contamination found. After QSA Global discussed the situation with Qual-X, Inc. and using their expertise in these types of situations, it was determined from survey readings and building size, that an estimated amount of less than 1-2 mCi may have been released. They also indicated that the sources were of the type that are known to leak due to the way they are manufactured and their age being 29 years. At this point QSA Global, Inc. believes that all three may be leaking. Event Report ID No.: LA160015 |
