The author and staff were associated with the Quartermaster Research and Development Laboratories, Army Medical Service Graduate School, Walter Reed Army Medical Center, and University of Rochester Atomic Energy Project. Field tests at UPSHOT-KNOTHOLE, shorts 9 and 10, were conducted in which Chester White pigs, clothed in Armed Services fabric assemblies or place behind a serious of open or fabric-covered portholes, were exposed to the effects of atomic explosions. These tests were carried out (1) to determine the protective value of a limited number of clothing combinations, (2) to obtain field information that could be related to laboratory data on fabric protective characteristics, (3) to investigate the value of a fire resistant treatment in reducing thermal injuries, and (4) to study the effect of various details of clothing design on thermal protection. Three different fabric assemblies were tested, each with and without a fire resistant treatment on the outer layer. These assemblies were (1) A four-layer Temperate ensemble (corresponding to the cold-wet uniform with the frieze liner removed) which provided excellent protection at all incident energies up to 40 cal/cm2 with no reason to doubt its efficacy up to 75 cal/cm2; (2) Hot-Wet 50/50 ensemble (5.2 oz provided good protection up to the highest energy levels for which data were obtained, 41.0 cal/cm2 for the untreated ensemble and 33.5 cal/cm2 for the treated; and (3) Hot-Wet ensemble (5.2 oz oxford over, 3.2 oz knit cotton underwear fabric), which was inadequate at energy levels from 9.0 to 50.0 cal/cm2, whether or not it was treated for fire resistance. Flaming was noted in some uniforms not treated for fire resistance. the treated assemblies gave better protection than their untreated counterparts, especially at the more distant stations, 5800, 6800, and 7800 ft from ground zero. Burns beneath the fabric assemblies at the higher levels of thermal energy were consistently less serious than anticipated from prior laboratory experience. Where the fabric was spaced away from the skin, the burns in general were less serious than where the fabrics were in close skin contact. Condition: Good.
