UV spectra of old sun lamps have been measured and found to contain significant amounts of UVC in addition to UVB and UVA irradiances. Their spectra are compared with that of a modern sunbed, a solar spectrum obtained with a solar elevation of 29.3 degrees and the extraterrestrial UV spectrum. The effects of UVC on human skin is rarely studied, but we know that UVB can be harmful. Old UVR lamps for cosmetic tanning irradiate significant amounts of UVB and UVC, and are therefore not recommendable. However, several action spectra indicate small health risks with limited UVA exposure, but a drastic increase in the UVA doses may be one reason for the increasing skin malignancies observed in western countries. Further research to clarify these observations has to be carried out.
已对老式太阳灯的紫外线光谱进行了测量，发现除了中波紫外线（UVB）和长波紫外线（UVA）辐照度外，还含有大量的短波紫外线（UVC）。将它们的光谱与现代日光浴床的光谱、太阳高度为29.3度时获得的太阳光谱以及地外紫外线光谱进行了比较。虽然很少有关于UVC对人体皮肤影响的研究，但我们知道UVB可能是有害的。用于美容美黑的老式紫外线辐射灯可辐射大量的UVB和UVC，因此不推荐使用。然而，一些作用光谱表明，有限的UVA暴露会带来较小的健康风险，但UVA剂量的急剧增加可能是西方国家皮肤恶性肿瘤发病率上升的原因之一。必须开展进一步的研究以阐明这些观察结果。
