Spectral monitoring of biologically active solar UVB radiation using an in vitro model of vitamin D synthesis.
Vitamin D synthetic capacity of sunlight is the most well known beneficial effect of solar UV radiation. The article describes the new method of biological dosimetry of solar (and artificial) UV radiation based on an in vitro model of vitamin D synthesis (D-dosimeter). Particular attention is given to spectrophotometric analysis of the multicomponent mixture of vitamin D photoisomers that has been developed for the most effective use of D-dosimeter in situ.
