The State of
Nebraska reported that 19
tritium exit signs that were held under general license by Albertsons Grocery Store are missing from a store location in Omaha. The signs were manufactured by NRD, Inc., Model T-4001, with each sign containing 19.8 Curies of
tritium in 1991. The State was informed in October of 2004 by Albertsons that the Omaha store had been sold to a "No Frills" supermarket chain. The State contacted "No Frills" in November 2004 and was informed that the signs could not be located. Investigation determined that the signs were removed by Albertsons in 2002 when the store was remodeled and replaced with electrical
exit signs. The Albertsons store manager at the time of the remodeling was not aware of what was done with the signs. The State also confirmed that with NRD, Inc. that the signs had not been returned to the manufacturer. The State believes that the signs were probably sent to a landfill and plans to close the investigation.
