When the COVID-19 pandemic emerged in early 2020, ultraviolet radiation became one of the go-to methods for preventing the spread of the SARS-CoV-2 virus, along with facemasks, hand sanitizer and social distancing.
The problem: There was little research showing what UV dosage kills the virus. What wavelength? How long? And could UV systems be installed in public places such as airports, bus stations and stores without causing long-term damage to people?
In a newly published study, researchers from Binghamton University’s Thomas J. Watson College of Engineering and Applied Science answer many of those questions and lay the foundation for health standards about what offers true disinfection.
The paper, titled “Systematic evaluating and modeling of SARS-CoV-2 UVC disinfection” and published in Scientific Reports, is written by Distinguished Professor Kaiming Ye, chair of the Department…
