Researchers from the United Kingdom’s Cranfield University used computerized simulations to demonstrate how comparatively safer far UVC radiation can be in disinfecting a room.
They consider this new information to be the secret to effectively eliminating aerosols contaminated with Covid-19, notably in enclosed spaces such as a clinic, a hospital room, an office, even a classroom.
The research that was published in Scientific Reports Journal says that a low dosage of UVC can boost the sterilization rate by a whopping 50% to 80% in comparison to an enclosed space’s ventilation alone. They also said that unlike common UVC – which also effectively eliminates microorganisms but poses a danger to humans – far-UVC is harmless to us.
The co-author of the research from Cranfield University, Liang Yang, said: “It is not always possible to socially distance in indoor environments, the chance of spreading the virus through aerosols contaminated with coronavirus increases.”
“This study has demonstrated that far-UVC can be a safer and more economical alternative in mitigating Covid-19,” said Yang.
The researchers also recognized the efficiency of far-UVC, which is comparable to N95 masks in an inadequately ventilated environment.
“With comprehensive and precise fluid dynamics modelling, we tracked and eradicated the contaminated aerosols,” explained Yang.
Yang’s co-author, Kirk Atkinson from Canada’s Ontario Tech University, said: “Imagine sterilization in just a simple flick of a light switch. That’s our main goal.”
“The government and businesses everywhere are investing substantially in ventilation. While ventilation by itself is not as effective in eliminating the virus. In comparison, far-UVC is more inexpensive to implement,” said Atkinson.
