Can ULTRAVIOLET light really Kill the novel coronavirus?

The first trending search of 2020 was undoubtedly the novel coronavirus

 

It brings us panic, but also promotes scientific progress and disaster response ability

 

During this period, we frequently heard a word - ultraviolet disinfection

Can ULTRAVIOLET light really Kill the novel coronavirus?

 

 

 

According to the popular knowledge about coronavirus published on the website of the Chinese Center for Disease Control and Prevention

 

The novel coronavirus is sensitive to organic solvents and disinfectants. 75% alcohol, ether, chloroform, formaldehyde, chlorine-containing disinfectants, peracetic acid and ultraviolet light can inactivate the virus

 

So ultraviolet light does kill the new coronavirus

 

Ultraviolet ray to kill bacteria kill virus, kill some microorganism effect is remarkable, especially to some bacteria and virus in the air are have killing effect

 

Therefore, it is very lethal to the new coronavirus. Generally, hospitals use ultraviolet light to disinfect.

 

In recent years, professional research on the application of ultraviolet home, ultraviolet sterilizing lamp, ultraviolet sterilizing rod and other products have been published, and have been widely used in this epidemic

The main working principle of ultraviolet products is to use the ultraviolet light released to inactivate bacteria and viruses, so as to achieve the effect of sterilization

 

Because DNA or RNA will strongly absorb ultraviolet light, and lead to DNA/RNA strand break, making bacteria or viruses inactive

Improper use of ultraviolet light is also easy to cause damage to people's body. Let's take a look at what to watch out for:

 

Precautions for use of UV products

 

1. Avoid direct contact with the human body. Ultraviolet radiation will damage the DNA in cells and cause damage to the human body

 

Most uv products contain the function such as induction of delay start, human body, which has achieved the protection to the body

 

 

 

2. When disinfecting the surface of articles with ultraviolet light, the irradiation surface should be directly irradiated by ultraviolet light, and sufficient irradiation dose should be achieved; People should not be exposed to ultraviolet light sources

 

So as not to cause damage. When the ultraviolet lamp is working, it is necessary for people and livestock to leave, and some items that are not suitable for ultraviolet radiation need to be covered effectively

 

 

 

3. Uv lamp disinfection should be combined with the indoor space to choose the appropriate UV lamp power, and then with the corresponding time (about half an hour).

 

 

 

4, ultraviolet disinfection lamp is to use ultraviolet light to kill including pathogenic microorganisms lamps, where the surface of the object contaminated by pathogenic microorganisms, water and air, can be used ultraviolet disinfection

 

The ultraviolet disinfection lamps used in China have high radiation intensity, more remote disinfection and sterilization effect, when used, must be used in the state of no one, to avoid the human eye and skin for a long time
