NEW MEXICO - Carlsbad officials are monitoring the presence of airborne radiation at the Waste Isolation Pilot Plant.
The U.S. Department of Energy says personnel are on-site on what officials are calling a "possible radiological event."
According to the D.O.E., an air monitor detected radiation on the plant's underground levels around 11:30 pm on Friday.
They say no employees were working underground at the time and workers on the surface have been sheltered.
Nobody has been found to be contaminated.
