Los Alamos National Laboratory Information

Location

4200 W. Jemez Road

Los Alamos, New Mexico

Operated by the University of California since its inception, Los Alamos National Laboratory designed, developed and tested the world’s first nuclear weapons. After World War II, Los Alamos (called the Los Alamos Scientific Laboratory) continued as an important nuclear weapons research and development facility. Research programs included nuclear physics, hydrodynamics, chemistry, metallurgy, radiochemistry and life sciences. LANL also used its research facilities to back up other areas of the weapons production complex, particularly plutonium processing and fabrication of weapon components.

Throughout the course of its operations, the potential for beryllium exposure existed at this site, due to beryllium use, residual contamination, and decontamination activities.
