faWwow dt aw & » bee SS AS OE A ON hE CL edd amount of protection from direct blast effects that may be provided by foxholes of uniform dimensions located within distances of a nuclear explosion that are recognized as lethal for combinations of thermal and ionzing radiations and indirect blast injuries. Sixteen dogs protected in foxholes were exposed in pairs to the nuclear detonation. Autopsies performed between 10 and 15 hours after the blast demonstrated mild to moderately severe lung hemorrhages and three instances of miid to moderately severe brain hemorrhage. Ruptured ear drums and blast damage to abdominal viscera were infrequent. Evidences of acute ionizing radiation injury consisted in decreases in absolute lymphocyte counts and changes in lymph nodes and spleens. Photographs and diagrams of foxholes, animals, and tissue speciments; graphs of blast pressures, gamma doses, and neutron fluxes are included.

In particular, it was desired to know the peak pressure as a function of distance in this region. Secondary objectives were to determine the path of the triple point and to determine the peak pressure in the Mach~stem region.
