Ultraviolet B light is needed for vitamin D synthesis in our bodies, but is a major cause of sunburn, skin cancer, cataracts, suppression of the immune systems, and photo-aging. Ultraviolet C light is extremely dangerous, but completely absorbed by the ozone in the

Laboratory Ultraviolet Light Sources - Princeton University
ehs.princeton.eduMany of the ultraviolet (UV) sources used in the laboratory emit high intensities of UV light, capable of producing painful eye and skin burns. This training presentation provides information about the hazards associated with UV exposure and the safety precautions to take when working with these sources.

esys.usThe C7027, C7035, and C7044 ultraviolet radiation sensing tubes have a life expectancy of 40,000 hours of continuous use within the flame detector's specified ambient temperature and voltage ratings. When an ultraviolet radiation sensing tube wears out, the UV sensor will fail to properly discriminate between flame conditions.

紫外線防御剤としての酸化亜鉛の機能と開発
www.soc.co.jpAbstract : Recently the infuence of ultraviolet ray of UVA range (320 to 400nm) on human skin has been studied. So a sunscreen agent is expected to shield UVA as well as UVB (290 to 320nm). In this report, the transparency and the UV shielding properties of inorganic UV shielding agents are discussed. Consequently
