Research Abstract

Ultraviolet Radiation is classified according to wavelength into three categories such as UV-A (315-400nm), UV-B (280-315nm), and UV-C (under280nm). In these categories, UV-B is especially dangerous by causing damages such as cataracts, loss of skin immunity, and increase in skin cancer. For this reason it is important to avoid overexposure to ultraviolet radiation. The first step in this avoidance is to understand the sky UV-B radiance distribution and reflection of UV-B in areas of human activity. Although sky luminance distribution has been studied around the world, the sky ultraviolet radiance distribution has not yet been studied. This study is designed to observe and analyze the sky UV-B radiance distributions. And ratios of ultraviolet radiance were calculated based on the regression equation of the sky UV-B radiance distribution of clear sky.
