Abstract

UVC222 nm has germicidal effects with potential clinical applications. However, UVC irradiation is capable of inducing DNA damage like cyclobutylpyrimidine dimers (CPD). Although new devices have emission peaks in the short-wavelength region of UVC (~222 nm), the remaining “collateral” radiation at longer wavelengths could be harmful to human health. We investigated the DNA damage caused by ...
