Long-term UVB and UVC irradiation can increase the skin cancer risk the researchers insist more on the carcinogenetic effect of UVB, but scale cells cancer of skin and malignant melanoma are caused by UVA radiation. Regard to broad use of UV (260nm) lamps in laboratory hoods, it is necessary to study the effect of UVC (260 nm) radiation on the skin. In this study, the effect of UVC radiation with wavelenght 260 nm on the skin and ear of one month and two months old Balb/c mice during 25, 50, and 100 hours exposure time have been investigated. The results show that UV (260nm) radiation increases the epidermis thickness. The other skin layers in both ages show alternate changes in different exposure times. Also, it may be concluded that the increase in hair follicles is not significant.
