Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

ISO/CIE 28077 was prepared by CIE Technical Committee 6-32, Action Spectrum for Photocarcinogenesis,

Introduction

Solar ultraviolet radiation (UVR) is recognized as a major cause of non-melanoma skin cancer in

human beings. Skin cancer occurs most frequently in the most heavily exposed areas and correlates

with degree of outdoor exposure. Describing the relationship of exposure (dose) to risk (skin cancer)

requires the availability of a biological hazard function or action spectrum for photocarcinogenesis. This

document proposes the adoption of an action spectrum (weighting function) derived from experimental

laboratory data and modified to estimate the non-melanoma tumour response in human skin. The

experimental data are sufficient for estimating effectiveness down to about 250 nm, but experimental

data are not sufficient for specifying effectiveness above 400 nm.

Note 1 to entry: The range between 100 nm and 400 nm is commonly subdivided into: UV-A: 315 nm to 400 nm;

UV-B: 280 nm to 315 nm; UV-C: 100 nm to 280 nm.

3.2 Symbols and abbreviations

SCUP Skin Cancer Utrecht-Philadelphia (an action spectrum proposed in Reference [1])

SCUP-m designates the original SCUP action spectrum, based entirely on mouse data

SCUP-h designates a proposed action spectrum estimated by correcting for differences in UV

transmissions between human and murine epidermis
UV-A1 wavelength range from 340 nm to 400 nm
UV-A2 wavelength range from 315 nm to 340 nm
4 The action spectrum for photocarcinogenesis of non-melanoma skin cancers

The effectiveness of ultraviolet radiation in causing photocarcinogenesis of non-melanoma skin cancers

[1-16]

has been studied for many years . The action spectrum defined in this document was first published

[16]

by the CIE as the product of research by CIE Technical Committee 6-32, as CIE 138/2. The document

stated the following recognized limitations to this action spectrum:

“The UV-A1 part (340 nm–400 nm) of the SCUP action spectra has large margins of uncertainty

(from 10 %–20 % at 340 nm to an order of magnitude at 390 nm); the minimum at 350 nm and

especially the secondary maximum at 380 nm are not well defined. Recent biochemical data do,

however, indicate that action spectra for some types of DNA damage from reactive oxygen species,

such as released by UV-A, show a minimum around 350 nm.

Exploiting this as yet ill-defined fine structure in the UV-A1 region of the SCUP-h action spectrum

(e.g. for optimizing commercial tanning lamps) would be unjustified. Because the Committee report

should provide a standard for risk assessment in regulatory applications, its recommendation

eliminates the uncertainty associated with the fine structure of the SCUP-h action spectrum.

Committee consensus involved flattening the plateau at the 340 nm level. Mathematically, this
