Recently, the development of coastal zone has been advancing, and the chance of human activity has increased near the sea. On the other hand, destruction of ozone layer has resulted in an increase in the amount of ultraviolet radiation reaching the earth surface. The human body is harmfully influenced as skin cancer and eye damage by ultraviolet radiation. Especially, the effect of ultraviolet radiation on beach is higher than that inland area due to the reflection from the sand surface. This report shows measurement method of ultraviolet reflectance on wide sand surface using ultraviolet radiation camera and reflection standard board. From the measurement results, the ultraviolet reflectance on sand is from 3 % to 8 %.
