New concerns now about a story we brought you yesterday. A radiation leak at the nuclear waste facility in New Mexico. Investigators now admit that the problem is serious. More than a dozen workers have been exposed. ABC's John mullers that been tracking it for us. Good morning. Reporter: Good morning, investigators know this much, a container of radioactive waste leaked underground at the waste isolation pilot plant or W.H.I.P. More tests being performed on anyone who came in contact. We had the fix the immediate problem before I can think about what happens in the future here. Reporter: The leak detect at W.H.I.P. Two weeks ago and the number of those affected could rise as they're tested. While officials insist the levels detected were lower than what you receive from a medical x-ray they admit it's too soon to tell how dangerous it could be for those exposed. Whenever you have a disaster there's always issues and mitigate and move forward. Reporter: Whip handles low grade nuclear waste located 26 miles outside of carlsbad near the Texas border. Right now officials are confident community members are safe. But they say they won't know the full extent of the leak until they can isolate and fix the problem. A process that could take several months. Until then the facility is closed to all but 183 essential workers. All right, the good news, investigators say a filtration system kicked in immediately and kept 99% of the radiation underground. The bad news, some did leak and could take months to fix. John, thank you.
