CIE 174:2006 PDF Download

The CIE 174:2006 standard focuses on the effect of ultraviolet radiation on the synthesis of vitamin D in humans. The report highlights historical observations linking sunlight exposure to the prevention of rickets and subsequent studies that have replicated these effects using artificial sources of UV radiation. The goal of the standard is to develop a standardized action spectrum that defines the specific wavelengths of UV radiation most effective in promoting the production of vitamin D in human skin.

The standard not only presents the results of various studies on vitamin D synthesis but also discusses the implications of these findings for determining the necessary UV exposure to meet the recommended daily intake of vitamin D. It acknowledges the importance of this information in promoting adequate vitamin D levels, which are essential for bone health and overall well-being.

Written primarily in English, the report also includes a brief summary in French and German. It consists of 16 pages, containing 5 figures and 1 table.
