With sudden, yet and a massive outbreak of Coronavirus Disease caused by novel coronavirus SARS-CoV-2, the consumers today seems more curious for safety, and thus rushing to buying Ultraviolet lamps to disinfect surfaces at work, commercial place, home, or other such spaces
Now, many justified answers have been provided to all individuals including customers, consumers/retailers by the FDA regarding the use of UV lamps for disinfection, especially during this Pandemic time.
Apart from understanding whether UVC radiation is effective at deactivating this harmful virus, there come few other concerns as well that, how effective UV radiation can be for killing other general viruses. It merely emphasizes on;
Direct exposure: An ultraviolet light radiation is effective for deactivating any virus provided that it is directly exposed to radiation. Therefore, the inactivation of infections on surfaces may not be powerful because of obstructing of the UV radiation by soil, for example, dust, or different pollutants, for example, natural liquids.
Doze & Duration: Many of the UVC lights sold for home use are of low portion, so it might take a longer presentation to a given surface territory to possibly give successful inactivation of a microscopic organism or infection.
In what Other Applications UV Light Is Harmful or Useful?
1. UV Light in Tanning
As we know that sunburn usually occurs as a common cause of excessive exposure to UV light. When our skin gets exposed to UVB rays, it allows natural defense mechanisms to kick in, and produce a pigment known as melanin which absorbs UV light, and spreads it as heat.
The skin goes darker as the body sends melanin into neighboring cells to prevent damage. Thus, the tanning booth uses artificial UV light in lamps that pass electric currents via gas in form of boiled mercury.
2. UV Light in Lamps
There are plenty of manufactured and natural substances that can absorb UV radiation such as; fungi, plants, and synthetic fluorophore. At the point when the UV light is assimilated, the electrons in the material arrive at a higher energy level before returning to their lower level in a progression of more modest advances. With each progression, they discharge part of their assimilated energy as noticeable light.
Fluorescent lights ionize fume in their cylinders, making electrons in the gas radiate photons at UV frequencies. A phosphor layer on the internal side of the cylinder changes the UV light into standard obvious light.
3. UV Light in Photography
Ultraviolet light is also used in photography, usually for scientific, medical, and other purposes, as it uses particular lenses to let UV light undergoes the camera’s lenses.
Nature photographers might use UV photography for capturing patterns in flowers that aren’t usually visible to the human eye. By adjusting cameras, they can only collect the UV light which hits the camera sensor.
What Queries to Consider in Mind While Buying Specific UV Lamp?
When you approach any ultraviolet lamp supplier, then ask them about the product’s safety risk, functions, specifications, health, and instruction availability for use/training information.
Find out if the item produces ozone.
Request what kind of material is viable with UVC sanitization.
Find out if the light contains mercury. This data might be useful if the light is harmed and you need to realize how to tidy up or potentially discard the light.
