Joint research between Kobe University and Ushio Inc. has provided proof for the first time in the world that direct and repetitive illumination from 222-nm ultraviolet radiation C (UVC), which is a powerful sterilizer, does not cause skin cancer. This suggests that 222-nm UVC is also safe for human eyes and skin. This technology is expected to have a wide range of antibacterial and antiviral applications in medical facilities and daily life.
