Long wave uv wavelength
WebUVA light, also known as long-wave light, accounts for about 95% of the UV light that reaches our skin. Although both UVA and UVB are bad for skin, UVA rays are more of a threat because a much larger percentage of them reach earth’s surface. They’re present all day long, year-round, even when it’s cloudy and the sun “isn’t out.” WebTo elucidate the mechanisms of mutation formation with UVA in human skin, we determined the spectra of UVA- and UVB-induced mutations in primary human fibroblasts. As with UVB, we found the majority of mutations to be C-to-T transitions also with UVA. For both UVA and UVB, these transitions were found within runs of pyrimidines, at identical ...
