Radioactive and chemical contamination threaten both the public and the environment because of more than 370 deteriorating, unnecessary, polluted Department of Energy buildings — and the agency says it doesn’t have the money to make them safe.

The buildings on the list, many of which are old and haven’t been used in a while, include 1940s and ’50s-era buildings where nuclear research and work was performed, such as structures at the Y-12 plant in Oak Ridge, Tenn., the one-time “secret city” that helped birth the Manhattan Project, and others at Los Alamos, N.M., and the Lawrence Livermore and Argonne national laboratories.
