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

Mice were used to assess biologically the inside environment of two designs of heavy concrete personnel structures subjected to nuclear blast. A sample consisted of 20 mice; one sample was used in each of l2 structures. Aside from two samples placed in unrealistic locations, there was no immediate mortality. By D+20 days two mice from the close-in shelters and seven from those further out had died. (auth)
