From the BBC:
There’s only one type of UV that can reliably inactivate Covid-19 – and it’s extremely dangerous.
“You would literally be frying people,” says Dan Arnold, laughing in disbelief.
Arnold works for UV Light Technology, a company that provides disinfecting equipment to hospitals, pharmaceutical companies and food manufacturers across the UK. Recently, as the global anxiety about Covid-19 has reached extraordinary new heights, he’s found himself fielding some unusual requests.
“We had an enquiry from a private individual about our equipment, saying ‘Well, why can't we just get one of your UV lights and put it up on the exit to the supermarket – people can stand under it for a few seconds before they go in’,” he says.
Among the abundant “health” advice that has been swarming around the internet in recent weeks, the idea that you can disinfect your skin, clothing or other objects with UV light has proved extremely popular – and even been mentioned by the US President.
