Résumé

Radiation dose vs. radiation intensity: Standardized lamps are used to provoke erythemal reactions in skin as required for SPF determination (Surber et al., 2021). For practical-experimental reasons, duration of irradiation is substantially reduced compared with the duration of irradiation in a consumers' everyday life. Concomitantly, radiation intensity is substantially increased to yield a comparable radiation dose. With current methods, it is assumed that specific erythemal reactions are dependent only on radiation dose and not on the rate at which energy is administered. Some experiments supported this assumption with human data for time periods from 1 second to 1 hour (Meanwell and Diffey, 1989). However, other studies describe a «reciprocity failures» (Iida et al., 2016). The extent to which this applies to the SPF determination has not yet been investigated.
