The following information was received from the State of
Utah via fax.
The Utah Division of Radiation Control [DRC] was notified at 1:38 p.m. MST on Wednesday, August 13, 2013 of an incident where a church chapel was destroyed by fire. The fire had occurred three months earlier on May 13, 2013. No one noticed the radiation symbol mixed with the trash until a representative of the church, watching the residue being shoveled from the chapel. He noted the radiation symbol stuck to the remains of the melted sign.
The DRC contacted the church representative and was informed of the details of the fire.
The DRC Radioactive Materials Section Manager was notified of the incident.
Notification to the NRC was completed on January 24, 2014.
The tritium sign was melted by the high heat of the fire. There were no remaining identifiable components. The debris from the sign was mixed with other burnt materials and the trash had been shoveled into waste containers. The church representative said there was nothing recoverable in the fire's residue.
The EXIT sign (Model B-100) was manufactured by SRB Technologies in 2005. The sign was designed to operate for 20 years using 18.9 curies of tritium. The estimated activity of tritium remaining inside the sign when it was destroyed was approximately 12 Curies.
