New Mexico officials are warning of a potentially "imminent" and "substantial" threat to the public after a radiation leak at a nuclear waste storage site.
Authorities say the leak may be the result of kitty litter.
Barrels of waste are routinely packed with kitty litter before containers are sealed.
Officials at the troubled Los Alamos facility recently switched to an organic product and that may have caused an unexpected chemical reaction contaminating 22 workers.
CNN's Tom Foreman has the story.
