Ultraviolet radiation (UV)


Are sunbeds like sunlight?

Natural UV radiation reaching the Earth's surface consists of approximately 95% UVA and 5% UVB radiation. Tanning parlours use different types of sunbeds, some emitting more, some emitting less UVB as compared to UVA. In the past, there was a trend towards a decrease of UVB and a corresponding increase in UVA. This was based on the experience that excessively UVB-rich sunbeds easily cause intermittent overexposures and risks of acute sunburns with a possible increased melanoma risk. On the other hand, excessive UVA exposure has lately been discussed as a possible melanoma risk factor in the scientific and regulatory community. Many sunbed manufacturers are now returning to relative amounts of UVA and UVB that mimic the natural composition in sunlight.
