Background

The 10-acre Safety Light Corporation (SLC) Site is located near Bloomsburg, Pennsylvania. Past activities at the site include the manufacturing of self-illuminated watches and instrument dials, smoke detectors, neutron sources, exit signs and other merchandise containing radioactive materials. The site includes buildings or structures and their contents, earthen lagoons, an abandoned canal and former dump areas, contaminated with radioactive materials, such as radium-226, strontium-90, cesium-137, and tritium. 

In 2005, EPA added the site to the National Priorities List (NPL), making it eligible for federal cleanup funds under the Superfund program.
