Employees at the Oak Ridge National Laboratory were evacuated Saturday morning after an operational emergency was declared.

Radiation alarms went off in Building 7920, the Radiochemical Engineering Development Center around 5:07 a.m. Later monitoring of the area revealed that no radiation had been released from the facility, according to the Operations Emergency Center in Oak Ridge.

The building is a laboratory where research, production and storage of materials such as medical isotopes take place.

Employees in nearby facilities were sheltered-in-place as a precaution, but that was lifted around 9:11 a.m.

Officials said emergency response personnel are preparing to enter the hot cell area to the REDC to reset air monitors that activated earlier and to assess current conditions.
