Abstract:
In various areas of professional activity, exposure of skin to ultraviolet radiation coming from artificial sources may occur. These UV rays differ from the solar UV radiation due to their intensity and spectrum. We review current developments with the introduction of statutory exposure limit values for jobs with UV radiation from artificial sources, a selection of relevant activities with artificial UV exposure and an overview of the occurrence of skin disorders and dermatologically relevant skin diseases caused by these specific occupational exposures. The latter is relevant for medical advice in occupational dermatology and occupational medicine. On the basis of existing studies on welders and studies regarding occupations with "open flames" (using the example of the glassblower) it is evident that so far no reliable data exist regarding the chronic photodamage or the occurrence of UV-typical skin cancers, but instead clear evidence exists regarding the regular occurrence of acute light damage in these occupations.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
