Nuclear Waste Site Workers Tested For Radiation

The nation's only deep underground depository of nuclear waste remains closed today and more workers there will be tested, following a still-unexplained Valentine's Day leak at the Waste Isolation Pilot Plant near Carlsbad, New Mexico.

At least 13 workers were exposed to radiation, and above-ground monitors at the site have detected elevated levels of radioactivity.

Jack Volpato, a county commissioner in Carlsbad, says "everybody's concerned" in his community about the leak. But he insists that the incident proves the safety systems work. He joins Here & Now's Meghna Chakrabarti.
