Vitamin D which is formed upon UV solar radiation in human skin is essential in many physiological
functions. To estimate beneficial vitamin-D-synthetic capacity of sunlight a bio-equivalent UV dosimeter that is based
on the same molecular photochemistry from which vitamin D is photosynthesized in human skin has been developed.
The examples of an in situ monitoring of the vitamin-D-synthetic capacity of sunlight using an in vitro model of
vitamin D synthesis are presented, and various operational principles of the UV biodosimeter are discussed. In
addition, reliable algorithm is presented for direct calculation of previtamin D3 accumulation using the photoreaction
mathematical model with solar UV spectra as input data. Critical dependence of previtamin D3 accumulation on
cloudiness and aerosols is demonstrated.
