USA Today: One technology that could be implemented to disinfect heavy-traffic areas on cruise ships is far-UVC light. Far-UVC light has the capability to scramble the genetic material of viruses such as coronavirus, effectively sanitizing the air, surfaces or even people.
“Ultraviolet light in general has been used to kill bacteria and viruses for a very long time,” David Brenner, director at the Columbia University Center for Radiological Research, told USA TODAY. It’s been known to kill bacteria and viruses for the last century and for the last two to three decades has been used to disinfect surgical theaters or hospital wards.
“It’s being used in the MTA here in New York, in the wee hours between 1 a.m. and 5 a.m. when the MTA is closed down,” he added, referencing the Metropolitan Transportation Authority public transit vehicles and some fixed locations being sanitized with UV light. “It’s been in use to kill viruses and sterilize locations when people aren’t around, which is not ideal because even if you have a sterilized location at 9 o’clock in the morning and people start coming in, they’re potentially gong to contaminate.”
