WebThe data shows that using a 30 mW/cm2 UVC light, almost 99.99% of the bacteria can be killed in one second, let alone increasing the intensity. Use UVC LED for different microbes. According to the different types of microorganisms, the time and intensity of ultraviolet light needed are also different. Web9 de mar. de 2016 · The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.
WebKilling of B. subtilis Spores by High Intensity UV Light 2 Rationale Bacterial endospores, of the type by Bacillus and Clostridium species, are known to be highly resistant to various forms of radiation and other physical and chemical agents. High-intensity ultraviolet light, however, was suspected to overcome such resistance and Besides the sun, there are numerous celestial sources of UV radiation. Very large young stars shine most of their light in ultraviolet wavelengths, according to NASA. Because Earth's atmosphere blocks much of this UV radiation, particularly at shorter wavelengths, observations are conducted using high-altitude … Ver mais UV radiation has enough energy to break chemical bonds.
