103/3 Reference Action Spectra for Ultraviolet Induced Erythema and Pigmentation of Different Human Skin Types

Increasing public awareness of acute cutaneous UV reactions created the need to evaluate UV induced erythema and pigmentation for any UV sources without carrying out time consuming and expensive experiments. A practical method is to convolute the spectral power distribution of the UV source with an action spectrum.

For white people with sensitive skin as well as for people with normal skin reactions action spectra for erythema and pigmentation are expressed as sets of exponential equations. When displayed on a log-linear scale each of the four action spectra consists of three straight lines.

These action spectra together with their threshold doses can be used easily to evaluate mathematically the photobiological effects of erythema and pigmentation for different skin types. This can save time and money if natural respectively artificial UV emitting sources have to be compared.

103/4 Biologically Effective Emissions and Hazard Potential of Desk-Top Luminaires Incorporating Tungsten Halogen Lamps

The contents of this report represent the combined efforts of the members of TC 6-18 in respect of investigations, both dosimetric and dermatological, concerning the potentially hazardous emissions of tungsten halogen lamps. The results of these investigations are presented as measurement data for a number of desk-top luminaires using tungsten halogen lamps and ananalysis of potential hazards to the unprotected skin and eyes with details of a dermatological study of the induction of erythema in humans
