Ultraviolet light is a commonly used sterilization and disinfection tool in the professional fields of medicine, drinking water and food. During the “SARS” period, it began to enter various public places and even families. Some are very similar in appearance to fluorescent lamps for home use. At present, there are not many people who buy it from ordinary families. However, because the warning signs on the products are not obvious, merchants often ignore the hazards in publicity. Consumers are often unaware of the harm caused by ultraviolet lamps to the human body. Therefore, in recent years, the damage caused by ultraviolet lamps happens sometimes.
The ultraviolet lamp uses the ultraviolet light emitted by the mercury lamp to achieve the sterilization and disinfection function. It emits a large amount of ultraviolet energy, and if there are no protective measures, it is very easy to cause huge harm to the human body. If the bare skin is irradiated by this kind of ultraviolet light, it will be red, swollen, itchy, and desquamated in the light ones; in severe cases, it may even cause cancer and skin tumors. At the same time, it is also an “invisible killer” of the eye, causing inflammation of the conjunctiva and cornea, and long-term exposure may cause cataracts.
For some small UV lamps used by restaurants and homes to eliminate mosquitoes, their luminous principles are different, and consumers need not worry.
If there are serious patients such as leukemia in the home, a relatively sterile environment is needed before the purchase of ultraviolet lamps is necessary. Never use ultraviolet lamps for ordinary home lighting. When ultraviolet lamps must be used for disinfection, direct contact with skin, eyes and ultraviolet radiation should be avoided. In public places, if you encounter ultraviolet disinfection, you should avoid it in time, especially to prevent children with thin skin stratum corneum from accidentally entering the ultraviolet operation area.
After being exposed to ultraviolet rays for a long time, the skin may become cancerous in the future. In medicine, as long as irradiating white mice for 20 minutes, it will produce obvious adverse symptoms. Ultraviolet radiation is damage to internal tissues. If it is just peeling, some medicine can be cured, but the damage to internal tissues must be observed for a long time.
Experts suggest that when using an ultraviolet lamp, there should be no one in the room. The disinfection time is 30 minutes to 1 hour; avoid looking directly at the light source; families must wear protective glasses or sunglasses when operating the disinfection lamp.

46 students worried about carcinogenic under the disinfection lamp. The skin of the restaurant was damaged by ultraviolet radiation during the meal, and 11 of them had abnormal blood, and the doctor said that there was a possibility of cancer.
