Irradiances and health risks associated with the use of UV lamps and sunbeds.

UV spectra of old sun lamps have been measured and found to contain significant amounts of UVC in addition to UVB and UVA irradiances. Their spectra are compared with that of a modern sunbed, a solar spectrum obtained with a solar elevation of 29.3 degrees and the extraterrestrial UV spectrum. The effects of UVC on human skin is rarely studied, but we know that UVB can be harmful. Old UVR lamps for cosmetic tanning irradiate significant amounts of UVB and UVC, and are therefore not recommendable. However, several action spectra indicate small health risks with limited UVA exposure, but a drastic increase in the UVA doses may be one reason for the increasing skin malignancies observed in western countries. Further research to clarify these observations has to be carried out.
