Objectives

The National Institute for Environmental Studies has a network of UV monitoring stations consisting of 5 own stations and other cooperating institutes in Japan, and monitors harmful ultraviolet radiation continuously. However, UV radiation has a merit for vitamin D synthesis in human skin. Our group has developed a system to estimate the UV radiation necessary for vitamin D synthesis, as well as the amount of vitamin D synthesized in the body, and started to provide these data on the website.
