Banyumas Library and Archive Agency in Central Java creates book steriliser with ultraviolet light
The machine called the Dropbox, sterilizes books with UV light, thought to be able to kill viruses contained in the droplets in the air. Shaped like a filing cabinet, the Dropbox consists of six drawers, each fitting 14 books. The books are warmed for 24 hours at 40 degrees Celsius and exposed to UV rays for 10 minutes. The books are arranged so that each receives an equal amount of radiation.
