Ultraviolet Spectral Reflectance and Transmittance under Coastal Exposure Test

Abstract

In recent years destruction of the ozone layer by CFC has resulted In Increasing levels of ultraviolet radiation, which causes serious damage to both humans and structures. To determine the potential damage from UV radiation to a coastal structure it is first necessary to evaluate the degree to which the construction materials reflect or pass the radiation. This research evaluated typical materials used In coastal architecture. Unfortunately, once In place, coastal structures are exposed to severe environmental factors such as strong winds and salt spray, Weathering of the surface could effect the materials ability to reflect or pass UV radiation. Future tests should thus be designed so that materials are evaluated after being exposed to a sufficient period of weathering.
