What effect will the UV disinfection lamp have for too long disinfection time?
The ultraviolet lamp uses the ultraviolet light emitted by the mercury lamp to achieve the sterilization and disinfection function. The ultraviolet energy radiated by it is relatively large. If there is no protective measure, it is easy to cause great harm to the human body. If the bare skin is irradiated by this type of ultraviolet light, redness, swelling, itching, and scaling will occur in the lighter ones; the more severe ones can even cause cancer and skin tumors. At the same time, it is also the "invisible killer" of the eyes, which can cause inflammation of the conjunctiva and cornea, and long-term exposure may cause cataracts. After prolonged exposure to ultraviolet rays, it may cause skin cancer in the future. In medicine, only 20 minutes of exposure to white mice will produce obvious adverse symptoms. Ultraviolet radiation damages internal tissues. If it is just peeling, apply some medicine to cure it, but internal tissue damage must be observed for a long time. Experts suggest that when using ultraviolet light, there should be no people in the room, and the disinfection time is 30 minutes to 1 hour; avoid looking directly at the light source; households must wear protective glasses or sunglasses when operating the disinfection lamp.
