THE INTERNAL ENVIRONMENT OF UNDERGROUND STRUCTURES SUBJECTED TO NUCLEAR BLAST. II. EFFECTS ON MICE LOCATED IN HEAVY CONCRETE SHELTERS

摘要

A cage containing 20 mice was placed in each of 12 underground shelters tested on shot Smoky in an attempt to assess biologically the inside environment of the shelters. Two sam¬ples of 20 mice each acted as controls. The structures, of French and German design, were located at ranges between 840 ft and 4320 ft from Ground Zero. Shot Smoky, a nuclear device, was exploded atop a 700-ft tower and had a yield of 43 kt.nAll but one group of mice were recovered on D+2 days. Aside from two samples placed in unrealistic locations, all animals were alive at recovery. With one exception, the peak pres¬sures in the chambers that contained mice were insignificant, ranging from a fraction of 1 psi to 1.6 psi.
