Repetitive irradiation with 222nm UVC shown to be non-carcinogenic and safe for sterilizing human skin

Joint research between Kobe University and Ushio Inc. has provided proof for the first time in the world that direct and repetitive illumination from 222nm ultraviolet radiation C (UVC), which is a powerful sterilizer, does not cause skin cancer. This suggests that 222nm 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. The research group consisted of members from the Division of Dermatology in the Department of Internal Related at Kobe University’s Graduate School of Medicine (Professor NISHIGORI Chikako, Associate Professor KUNISADA Makoto, graduate student YAMANO Nozomi et al.) and Ushio Inc. https://www.eurekalert.org/pub_releases/2020-04/ku-riw040720.php
