SKY AND SAND SURFACE RADIANCE DISTRIBUTION OF ULTRAVIOLET RADIATION

摘要

Middle wavelength ultraviolet radiation (UV-B, 280-315nm) is especially dangerous, causing damage such as cataracts, loss of skin immunity, and increase in skin cancer. This study is designed to measure the radiance distribution of sky and ground of UV-B. As results of measurement, it is concluded that the radiance increased as the altitude angle increased on sky UV-B radiation distribution. On ground reflection distribution, the radiance decreased as the altitude angle decreased.
