This technology is not a new technology, because it is directed against ultraviolet radiation of various bacteria.
Mexico City (apro). -Julio César Molina, head of the Laboratory of Lighting Technology Center of the Autonomous University of Guadalajara (UAG), and his team developed a lighting device called UVC that can eliminate 99.9% of the coronavirus space in a closed state .
However, the World Health Organization (WHO) guarantees that this light is ultraviolet radiation and is carcinogenic.
?? The main way of infection is through the air. “Many of us think this is caused by the surface, but research ensures that the air is the air that carries SARS-CoV-2 from one place to another,” Molina said in an interview with El Universal.
The lighting is developed by Construlita and can be used for SARS-CoV-2 and other pathogens, bacteria and microorganisms, such as Legionella, Pneumophila, Paradysteria, Staphylococcus albicans, Streptococcus, Pseudomonas aeruginosa and Typhimurium, etc.
According to Molina, he got help from the Autonomous University of Guadalajara (UAG) and relied on similar work prepared by Boston University. Therefore, they simulated the mist sprayed from the patient through the nebulizer system, and through the use of lighting can verify that it has been eliminated.
Heinz-JörnMoriske, executive director of the Indoor Air Hygiene Committee of the German Environment Agency, believes that the current state of research on this topic is a key point, because there is almost no data on the use of UVC for air disinfection.
?? How big is the room? How often does the air pass through the UVC lamp? What is the radiant intensity of each lamp? All of this has a great influence on how much damage you have to the bacteria in the room. He pointed out that, given that the air circulation between buildings varies from room to room, and even from corner to corner, it is difficult to generalize what is gained from laboratory scientific research.
For Molina engineers, the product has two lighting systems: general lighting system and ultraviolet lighting system. When integrated, it can be easily placed in schools or hospitals without any obstacles.
is it safe
This technology is not a new technology, because it is directed against ultraviolet radiation of various bacteria. It is divided into UVA (long wave), UVB (medium wave) and UVC (short wave), and in addition to irritating the skin and eyes, they are also considered by the WHO as possible human carcinogens.
?? However, at the end of September last year, researchers at Hiroshima University discovered that a certain amount of ultraviolet (UVC) can eliminate SARS-CoV-2 within 30 seconds without putting people at risk? Universal Publishing Company cited the “American Journal of Infection Control.”
In other countries/regions, this technology is called short-wave ultraviolet (UVC) lamps. Moreover, it can resist bacteria in water and air, and because people know that it can be spread through aerosols in the air, UVC disinfection has once again attracted the attention of the industry.
The German Federal Environment Agency is concerned about the use of this technology, which has not been recommended by the Robert Koch Institute or the Federal Ministry of Environment, which is responsible for disease control and prevention in the country.
However, some people have used these lights in their homes and they have been sold by companies such as Signify in the Netherlands.
Signify UVC expert Christian Goebel admitted: “In Europe, people have more concerns about how to use technology safely.”
If people in the room turn on these devices for any reason and the lights are still on, it may cause severe burns to the skin and eyes. Heinz-JörnMoriske, the German Environment Agency.
