Abstract
Clothing on dummies and fabrics on panels, protective cream on panels, and boxes were exposed to the thermal radiation of Shots 6 and 8 of Operation SNAPPER as part of Exercise Desert Rock IV. Exposures were made at 4, 5, 10 and 13 langleys (1 langley equal 1 calorie per sq. cm.). Protection was measured with temperature indicators. The clothing included standard items making up various ensembles, such as hot wet, hot dry, temperate, cold wet and cold dry. The fabrics on panels included essentially the same fabric combinations and various other fabrics to study reflectance, insulation, a variety of materials, including heat treated orlon, wool and synthetic fiber blends, and arrangements, including spacing and order of layers. Except for a few items there was little damage at 5 langleys. The exceptions were the cotton nylon parka which shredded, the fur ruff which melted and the wool fabrics which scorched slightly. At 10 to 13 langleys all single layers of fabrics and all outer layers of fabric combinations were badly damaged. The damage to fabrics as clothing and on panels was about the same and any differences can be accounted for on the basis of angle of incidence.
