Question 678

What are the risks of occupational exposure to "black" fluorescent lamps? - MB
By "black" lamps, you mean ultraviolet lamps. Since ultraviolet light is able to cause chemical damage to biological tissue, long-term exposure to this light isn't so good. How much risk there is depends on how much ultraviolet light they produce and how near you are to them. Sunlight contains a considerable amount of ultraviolet, so long exposure to sunlight burns and ages skin. The photons of ultraviolet light contain enough energy to cause changes in molecules and thus upset the cellular machinery that keeps us healthy. Ultraviolet lamps will do the same thing, given enough intensity and time.
