Most natural surfaces such as grass, soil and water reflect less than 10% of UV radiation. However, fresh snow strongly reflects around 80% of UV radiation. Sand also reflects 10-25% of UV radiation.
WebAnother proposal evaluated the different microorganism’s species inactivation with high intensity ultraviolet light with pulses of 325 µs duration in a range of 190 to 1.00 nm (including the regions of the UV−A, B and C−spectrum, in different percentages). 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. Due to their higher energies, UV photons can cause ionization, a process in which electrons break away from … Ver mais Most of the natural UV light people encounter comes from the sun.
