The Ultraviolet (UV) disinfection tower will disinfectant high infection-prone areas more rapidly and make them chemical-free. The name of the equipment is 'UV blaster.' It is mainly used for rapid and chemical-free disinfection of COVID-19 infection-prone areas. The equipment named UV Blaster is a UV-based area sanitizer designed and developed by the Laser Science & Technology Centre (LASTEC). LASTEC is a Delhi based premier laboratory of DRDO and has grown it with M/s New Age Instruments and Materials Private Limited, Gurugram.
Uses of UV Blaster:
It is used for top tech surfaces like equipment, computers, and other gadgets in laboratories and offices that aren't suitable for disinfection with chemical methods. It will also be useful for those areas where there is a large flow of people, including airports, shopping malls, metros, hotels, factories, offices, etc.
What is it made of?
The equipment has six lamps, each with 43 watts of UV-C power at 254 nm wavelength for 360-degree illumination. It can also be remotely operated through a laptop/mobile phone by using a wifi link. According to the Defence Ministry, the disinfection time is about 10 minutes for almost a room of 12X12 feet dimension and 30 minutes for 400 square feet area by positioning the equipment at different places within the room. Additionally, on an accidental opening or human intervention, the sanitizer switches off. It has a safety feature, the key to arm operation.
What is Ultraviolet (UV) radiation?
Ultraviolet light is a type of electromagnetic radiation. It has shorter wavelengths than visible light.
Sources:
The source of UV radiation is the Sun. It is subdivided into UV-A, UV-B, and UV-C. UV-A rays have the longest wavelengths, whereas UV-B and UV-C rays have the shortest wavelengths. UV-A and UV-B rays are transmitted through the atmosphere. The ozone layer absorbs all UV-C and some UV-B rays. Therefore, most of the UV rays that you may come in contact with are UV-A with a small amount of UV-B. Both UV-A and UV-B rays can cause damage to the skin. The short-term overexposure causes sunburn, while premature aging and skin cancer is a side effect of prolonged UV exposure. Exposure to UV-B rays increases the danger of DNA and other cellular damage in living organisms.
Wrap up:
To fight against COVID-19, it is essential to remove an infection from the surface of the objects, and the UV disinfection tower 'UV Blaster' will help to do the same.
