This study compared how well minimal erythema doses predicted using the reference action spectrum for UV erythema proposed by the International Commission on Illumination (CIE) in 1987 agreed with those observed in phototesting a large number of subjects with normal responses to sunlight to six different wavelengths of UV radiation (UVR) between 300 and 400 nm. It was found that, within the limits of experimental error, the hypothesis that the CIE reference action spectrum is a valid predictor of the erythemal effectiveness of different wavelengths of UVR could not be dismissed. There is no strong reason, therefore, why the CIE action spectrum should not continue to be used as a reference to compare the erythemal effectiveness of different broadband sources. However, close examination of the residuals from the regression analysis suggested that the erythemal sensitivity of skin at longer UV wavelengths (> 350 nm) in the population studied here is greater than predicted from the CIE reference action spectrum.
本研究比较了，使用国际照明委员会（CIE）1987年提出的紫外线红斑参考作用光谱预测的最小红斑剂量，与对大量对阳光有正常反应的受试者进行光测试时，在300至400纳米之间六种不同波长的紫外线辐射（UVR）下观察到的最小红斑剂量的吻合程度。研究发现，在实验误差范围内，CIE参考作用光谱是不同波长UVR红斑效应的有效预测指标这一假设不能被推翻。因此，没有充分理由不继续使用CIE作用光谱作为参考，来比较不同宽带光源的红斑效应。然而，对回归分析残差的仔细检查表明，在此处研究的人群中，较长紫外线波长（> 350纳米）下皮肤的红斑敏感性高于CIE参考作用光谱的预测值。
