NRC REQUESTS ORGANIZATIONS TO REPORT ON
TRITIUM EXIT SIGNS IN THEIR POSSESSION |
|||||||||
The Nuclear Regulatory Commission has requested 61 organizations to check tritium exit signs in their possession against their records and to report any lost or missing signs to the agency. The NRC’s action follows an inspection of Wal-Mart Stores, Inc., conducted in December and discussed in a meeting with Wal-Mart officials this week. A year-long audit by Wal-Mart identified approximately 15,000 tritium exit signs lost, missing, or otherwise unaccounted for at its stores and warehouses nationwide. Wal-Mart, which kept the NRC informed of its audit, expects to submit a formal report to the agency in late January. Tritium exit signs pose little or no threat to public health and safety and do not constitute a security risk. However, the NRC requires proper recordkeeping and disposal of all radioactive materials. Proper handling and recordkeeping are important, because a damaged or broken sign could cause minor radioactive contamination of the immediate vicinity, requiring a potentially expensive clean up. "Wal-Mart’s inability to account for all the tritium exit signs the company purchased demonstrates that organizations may not be fully aware of the regulatory requirements for owning these signs," said George Pangburn, deputy director of the NRC’s Office of Federal and State Materials and Environmental Management Programs. "The NRC wants to be certain that organizations are aware of their responsibility to properly account for tritium exit signs in their possession and to dispose of them properly at the end of their useful life." In a "demand for information" issued today, the NRC asked organizations possessing 500 or more tritium exit signs to report in writing to the NRC within 60 days the following information: An explanation of how the organization ensures compliance with regulatory requirements applying to the possession, transfer and disposal of tritium exit signs the organization has acquired;
The organizations receiving the demand for information were identified through the NRC’s General License Tracking System, which contains information filed by device manufacturers regarding initial distribution of the signs. The organizations include large retail store chains, churches, federal and state agencies, school districts and universities, among others. The signs are considered "generally licensed devices," because they are inherently safe enough to be handled or used by anyone with no radiation training or experience. Although purchasers – known as "general licensees" – do not need authorization from the NRC or a state regulatory agency to possess the signs, they are subject to certain regulatory requirements regarding handling, transfer or disposal of the signs. They are also subject to NRC or state inspection and enforcement action (including fines) for violating those requirements. From 2001 through 2007, Wal-Mart purchased approximately 70,000 tritium exit signs to install in its stores and warehouses. Last year, after discovering some signs were missing, the company initiated an audit of all its facilities. The NRC and its Agreement States (the 35 states that regulate radioactive materials under agreements with the NRC) have been kept informed of Wal-Mart’s progress in its audit. The company is now in the final stages of removing tritium exit signs from its facilities and returning them to the manufacturers in accordance with NRC regulations for proper disposal. The NRC reminded manufacturers and general licensees of the regulatory requirements for tritium exit signs in a Regulatory Issue Summary (RIS 2006-25) issued in December 2006. The requirements are also spelled out in NUREG-1556, Consolidated Guidance for Materials Licensees, Volume 16, Appendix L. More recently, the NRC posted a Fact Sheet on tritium exit signs on its Web site.
