Summary

PLUMBBOB - 1957 - NEVADA TEST SITE -- Interior view of the dual-purpose garage and mass shelter, sponsored by the Federal Civil Defense Administration, showing two of the three rows of support columns. Radiation dosimetry and other instrumentation will be installed in the huge room which is approximately 90 feet square. The shelter was designed as a segment of a dual purpose structure, and could be expanded to any desired size. It is under three feet of earth, with a reinforced concrete roof slab two feet, six inches thick. The structure could be used as an underground garage in peacetime and converted to use as a shelter in time of emergency.
