The most likely sources of UV light in the lab setting include: Transilluminators (used to visualize DNA bands in gels) Crosslinkers. Germicidal lamps in biological safety cabinets. Handheld UV lamps. UV Lasers. Blue-emitting LEDs used for photocatalysis (some of the emissions fall into the UV range) Sep 12, 2019 · UV radiation is a form of electromagnetic energy. It can come from natural sources, such as sunlight, as well as artificial sources, such as lasers, black lights, and tanning beds.. The sun is the Jan 1, 2010 · The major source of ultraviolet radiation is solar radiation or sunlight. However, exposure to artificial sources particularly through tanning salons is becoming more important in terms of human Although all people are exposed to natural sources of radiation, there are two distinct groups exposed to man-made radiation sources. These two groups are: Members of the public. Occupationally exposed individuals. A member of the public is defined in 10 CFR Part 20 as any individual except when that individual is receiving an occupational dose. Sep 14, 2020 · UVC is the shortest wavelength of the three forms of UV. The shorter the wavelength, the more harmful the UV radiation. However, lucky for us, UVC isn't able to penetrate earth's atmosphere. So while UVC is the most dangerous because it's the shortest wavelength, it's not a risk to the typical person because the sun's natural UVC emissions don Ultraviolet radiations help our body synthesize vitamin D. When our body is exposed to UV waves, the cholesterol present in our skin releases energy and gets converted into vitamin D. One of the prime sources of UV radiation is the sunlight, which is why doctors recommend a healthy exposure to sunlight to overcome the vitamin D deficiency. 5. .
