Solar Simulators for Healthy Vitamin D Synthesis

摘要: Background/aim The angular distribution of solar radiance and its spectral characteristics is required for the determination vitamin D3 production in humans. Materials methods weighted exposure can be calculated by integrating incident over all relevant parts human body. A novel instrument allowing simultaneous measurements from more than 100 directions has been developed. large simulator controlled experiments described. Results In summer it relatively easy to obtain sufficient D because sun times are short. winter solstice cannot obtained with realistic clothing even if were extended daylight hours. Conclusion Improved determine assess positive effects UV radiation natural variability.
