What are the health risks of UVA, UVB and UVC radiation?
The SCCP opinion states: 2(a) What are the differences between risks associated with exposure of persons to natural UVR and those risks from artificial UVR? There are no physical differences in type of radiation between natural and artificial UVR per se. However, there are important differences in the spectral distribution and absolute and relative irradiances of UVR from the sun and artificial sources, and between different artificial sources as shown in Figure 1. There is no standard solar spectrum because this varies with factors such as season, latitude and time of day. From a physical standpoint, the UV emission from sun is primarily within the UVA range. Artificial emission spectra are different from solar emission spectra from a physical point of view. Emission spectra of solar UVR and two tanning lamps It is relatively easy to compare the acute risks of exposure to natural and artificial UVR, which are similar, the details of which are discussed in Section 4. It is much more di
