abstract

Ultraviolet radiation is divided into UV-A (320–400nm), UV-B (290–320nm), UV-C (under 290nm). Of these, UV-B may be cause serious health problem, such as cataracts, loss of skin immunity, and increase of skin cancer. For this reason, it is important to know how to protect human body against the UV-B radiation. Beach shade is very effective to prevent the radiation. The radiation enters to the shade from sun and sky. The first step is to measure the sky radiance distribution of sun and sky radiation spectrum. We calculate erythema action radiation from the radiation spectrum. Sunburn chart is made using distribution of the erythema action ultraviolet radiation. Using the Sunburn chart, the shade is designed for protect against the UV radiation.
