In contrast, UVB is high-energy radiation, since it has shorter wavelengths. What Is UVA? When you think of UVA, think “A” for aging. Ultraviolet A (UVA) radiation is chiefly responsible for aging your skin and triggering skin cancers. This is because UVA rays have the longest ...
UVA testing uses ultraviolet light with a wavelength of 320-400 nanometers, while UVB testing uses ultraviolet light with a wavelength of 280-320 nanometers. The relationship between UVA testing and UVB testing mainly reflects the different effects of different wavelengths of ultraviolet radiation on...
UVA is further subdivided into UVA1, which has longer wavelengths closer to the visible range (above 340 nm) and UVA2, with shorter wavelengths closer to the UVB range (below 340 nm). The reason UVA is less famous than UVB is that the dangers of UVA weren’t well researched until relat...
A non-dimer type of DNA damage does not appear to play a major role in either UVA or UVB mutagenesis. Therefore, the previously reported increasing mutagenicity per dimer with increasing wavelengths cannot be due to non-dimer DNA damage. Differences in the cellular response to UVA and UVB, ...
UVA and UVB components of sunlight are implicated in melanomagenesis; however the majority of studies have focused on the effects of UVB and UVC light. Interestingly, melanoma tumour sequencing has revealed an overrepresentation of mutations signature of unrepaired UV-induced DNA damage. Repair of ...
Among all wavelengths of ultraviolet rays, only short wave ultraviolet UVC has the function of sterilization and disinfection. It belongs to a pure physical disinfection method. It has the characteristics of broad spectrum, high efficiency, fast and complete, no need to add chemical agents, no dru...
The UVA-UVB output was measured using a model UV-400 Research Radiometer (I cel) with a radiometer sensor for UVA and UVB. The majority of the resulting wavelengths were in the UVB (290–320 nm; above 90%) and UVA (less than 10%) range and the peak emission was recorded at 314...
UVA (wavelengths 320–400 nm) comprises more than 95% of the solar UV radiation that reaches Earth, making it far more abundant than UVB (280–320 nm) that accounts for the remainder. Most of UVB and all of UVC (wavelengths below 280 nm) are removed by the ozone layer and these short...
Sunscreen composite particles for UVA and UVB protection are described. The particles are substantially free of supplied UVB sunscreen and are prepared with a UVA sunscreen suitable
