Los Alamos Underestimates Radiation Leak Risk.

Located about 35 miles outside of Santa Fe, the Los Alamos National Laboratory is the birthplace of the atomic bomb and was the site of deadly radiation accidents early in the nuclear age. It currently houses four metric tons of plutonium, according to the government. That is approximately as much plutonium as is contained in the nuclear weapon arsenals of Britain, China, France, India, Israel, and Pakistan combined, according to Hans M. Kristensen of the Federation of American Scientists.
