Kobe University-Ushio Inc. Joint Study Finds Repetitive Irradiation with 222 nm UV-C Does Not Cause Skin Cancer

Oude Meer, The Netherlands (April 2020) – Ushio Inc. (TYO: 6925; headquarters in Tokyo, Japan) and a research group from the Division of Dermatology, Department of Internal Medicine, Graduate School of Medicine, at Kobe University (Professor Chikako Nishigori, lecturer Makoto Kunisada, graduate school student Nozomi Yamano, et al.), have demonstrated a world first via animal experimentation that repeated irradiation of 222 nm ultraviolet radiation (UV-C) with high disinfection capabilities does not cause skin cancer, suggesting that it is safe for exposure to human skin and eyes.  This technology is expected to be utilised in a wide range of antibacterial and viral inactivation applications in the medical field, as well as many opportunities for use in daily life.
