Abstract: 

All of the ultraviolet wave radiations, including UVA can alter the immune system of the skin. Scale cells cancer of the skin and malignant melanoma are caused by UVA radiation, but researchers insist more on the carcinogenetic effect of UVB spectrum. UVB spectrum is produced from the sun, sodium vapor lamp and electric and welding radiation of metal electrodes. In this study, the effect of UV produced from the metal electrodes on the skin and ear of one month and two months years old Blab/c mice during 25, 50 and 100 hours exposure time have been investigated. The results show that UV irradiation from welding decrease the number of hair follicles. Also increase in epidermis thickness and external and internal epidermis of ear is significant in one month and two months years old mice. The other skin layers in the same ages show alternate changes in different exposure times. It may be concluded that the incerase in epidermis thickness under UV radiation caused by welding can induce skin cancer and decrease of hair follicles may increse pathological risk of the skin.
