Abstract:

For the purpose of evaluating their resistance to the thermal radiation of atomic explosions, the critical thermal energies of five cargo well cover materials were determined. The materials were evaluated by exposure to a carbon-arc source of thermal radiation and examination of the consequent damage to the material surfaces. The methods of exposing the materials to determine critical energies were indicated. All of the materials ignited during exposure, but did not sustain a flame upon thermination of the pulse. The effects of weathering varied, but were in most cases considerable. Industrial weathering was found to cause a greater reduction in critical energies for a given effect than marine weathering. Scrubbing of the materials upon weathering improves their resistance to thermal radiation somewhat. Author
