(Summary description)       Ultraviolet rays have the effect of disinfection. Because of this effect, some restaurants, hotels, hospitals and other places are now installed, and even some homes have installed ultraviolet lamps. It can be said that it has been widely used in life. However, there have been some injuries caused by the unreasonable use of ultraviolet rays recently, so we must pay attention to how to use ultraviolet rays safely.         Ultraviolet lamps are commonly used sterilization and disinfection tools in professional fields such as medicine, drinking water and food. During the "SARS" period, they began to enter various public places and even families. Some are similar in appearance to domestic fluorescent lamps. At present, many ordinary families buy it. However, because the warning signs on the products are not obvious, businesses often ignore its harmfulness in publicity, and consumers often do not realize the harm of ultraviolet lamps to the human body. Therefore, in recent years, the misuse of ultraviolet lamps has caused Injuries happen from time to time. The ultraviolet lamp uses the ultraviolet light emitted by the mercury lamp to realize the function of sterilization and disinfection. If the bare skin is irradiated by this type of ultraviolet light, it will cause redness, swelling, itching, and scaling in mild cases; in severe cases, it may even cause cancer and skin tumors. At the same time, it is also an "invisible killer" of the eyes, which can cause inflammation of the conjunctiva and cornea, and long-term exposure may lead to cataracts. For the small ultraviolet lamps used by some restaurants and households to eliminate mosquitoes, their light-emitting principles are different, and consumers do not need to worry. If there are critically ill patients such as leukemia at home, a relatively sterile environment is needed, so it is necessary to purchase ultraviolet lamps, and ultraviolet lamps must not be used for ordinary household lighting. When it is necessary to use ultraviolet lamps for disinfection, it is also necessary to avoid the skin, eyes and ultraviolet rays. If the eyes and skin are exposed to ultraviolet lamps for more than 3 minutes, it may exceed the safety limit of the human body. After 15 minutes of direct exposure, the cornea will be damaged and lead to electric light. Ophthalmia, long-term exposure may also induce cataracts and skin cancer. Therefore, when using ultraviolet disinfection lamps, there should be no one in the room, and the disinfection time is 30 minutes to 1 hour.
