CARLSBAD, N.M. (AP) — A mysterious radiation release that has indefinitely shuttered the federal government's only permanent nuclear waste dump may have been caused by a switch in the type of kitty litter that is mixed with the toxic waste.
That's one of the theories that officials are exploring.
The Carlsbad Current-Argus (http://bit.ly/1iIHsdz ) Tuesday reports that a scientist who worked at the facility until 2010 says he believes a change from non-organic to organic litter caused a chemical reaction inside a waste drum, releasing the radioactive isotopes.
New Mexico Environment Department Secretary Ryan Flynn confirmed he has heard Department of Energy officials discuss the possibility that kitty litter may have been to blame for the radiation leak. Flynn says it's just one of many theories the DOE is exploring and nothing's certain right now.
