This ISO/CIE International Standard was prepared by the International Commission on Illumination (CIE) Technical Committee 6-32, Action Spectrum for Photocarcinogenesis, in cooperation with Technical Committee ISO/TC 274, Light and lighting.
This third edition cancels and replaces the second edition (ISO/CIE 28077:2016), which has been technically revised.
Solar ultraviolet radiation (UVR) is recognized as a major cause of non-melanoma skin cancer in humans. Skin cancer occurs most frequently in the areas of the body most exposed to solar radiation, and correlates with the duration and intensity of outdoor exposure to UVR. Describing the relationship of exposure (dose) to risk (skin cancer) requires the availability of a spectral weighting function or action spectrum for photocarcinogenesis. This document proposes the adoption of an action spectrum derived from experimental laboratory data and modified to estimate the non-melanoma tumour response in human skin. The experimental data are not sufficient for specifying effectiveness above 400 nm, but are sufficient for estimating effectiveness from 400 nm down to 250 nm.
