New coronavirus control and UV light tester

New coronavirus control and UV light testerAbstract: Under the ravages of new coronaviruses, the irradiation of ultraviolet germicidal lamps can effectively control the virus, but the use of germicidal lamps is inseparable from the ultraviolet intensity detector.During the Lunar New Year in 2020, the outbreak of new coronavirus in my country put the whole country into a high alert state, and government departments also issued a request to the public not to gather multiple people to avoid the continued spread of new coronavirus. During this period, places of entertainment, cinemas, temples, restaurants and other places in the country where people can gather are all closed. Even if the public needs to wear masks on the street due to their daily needs, it is conceivable that the spread of the new coronavirus is How strong is it. Use ultraviolet germicidal lamp to eliminate new coronavirus In a hospital with a large number of people every day, the new coronavirus may have become a hiding place here. The patients diagnosed every day are inside, and the patients who have fever are waiting to be diagnosed. Even if the patients are removed, there are many new coronaviruses on the protective clothing of the doctors and nurses who care for the patients. Even if it does not directly infect healthy people, the new coronavirus will survive in the air for several hours, and it is prone to secondary transmission. Therefore, the ultraviolet sterilization lamp is a sterilization tool that the hospital needs at this stage. Speaking of ultraviolet germicidal lamps, it is actually a low-pressure mercury lamp, which uses low-pressure mercury vapor to be excited to emit ultraviolet rays to kill viruses. The ultraviolet rays that are stimulated cannot be seen by the naked eye. Ultraviolet germicidal lamps also have two wavelengths of ultraviolet light. Generally, ultraviolet light with a wavelength of 253.7nm is used to cause the cross-linking of nucleic acids and proteins to rupture the virus, so that the nucleic acid loses biological activity and causes the death of the virus. The ultraviolet sterilization lamp with a wavelength of 185nm will react to release ozone for sterilization, which is called ozone lamp. However, it is necessary to know whether the ultraviolet sterilization lamp can effectively kill the new coronavirus in the hospital. It is necessary to use an UV light tester to detect the ultraviolet intensity of the sterilization lamp. As long as the intensity reaches the standard, it will continue to effectively kill the new coronavirus.
