| Title | Agreement State Report - Tritium Release from Exit Signs |
| Event Description | Wal-Mart stores reported to Oklahoma DEQ that they had found three damaged tritium exit signs during an audit of their signage. Two of the signs released tritium, the third did not release tritium. All three signs were at the Wal-Mart in Enid, Oklahoma. It appears that the signs were damaged by a 'walkie stacker' (similar to a fork lift) at an unknown date in 2003. The radioactive content of the signs was not recognized at the time of the damage. All three signs have been sent to Isolite for disposal or recycling. The signs were manufactured by SRB Technologies, Inc. Serial numbers of the leaking signs were 290130 and 290103.
Wipe tests revealed removable contamination of about 800 dpm/100 sq. cm on the wall directly behind one sign, and a maximum removable contamination of 82,800 dpm/100 sq. cm on the cement floor below the other sign. Both leaking signs were in the shipping and receiving area of the store. Wal-Mart has hired Dade Moeller & Associates as consultants, and this company took the measurement and conducted remediation. Dade Moeller states that they will have a technician at the store to remediate the remaining contamination by the end of this week.
This report is a duplicate of EN 44225. EN 44225 will be removed from the database and the public website.
An update was provided from Ralph Johnson to Joe O'Hara at 0914 on 3/19/09. Wal-Mart in Oklahoma performed an inventory of their generally licensed tritium exit signs and confirmed that a total of twelve were broken. This update corrects a previous update to a duplicate event notification. Notified R4DO (Pick) and FSME (Schaffer). |
