This study aimed to evaluate the ultraviolet-C (UVC) effects of radiation on the skin of Wistar rats and its impact on blood parameters. Forty adult rats were used, divided into a control group and three experimental groups exposed to artificial UVC (254 nm) radiation for 8, 16, and 24 days, 8 hours per day. Transmission electron microscopy results showed progressive damage to skin cells with increasing exposure time, including: nuclear envelope irregularities, mitochondrial swelling, increased melanin granule accumulation, keratinocyte and collagen filament disruption, and widening of cell junctions. In addition, blood analysis revealed significant changes in blood parameters: decreased hemoglobin and red blood cell (RBC) levels with longer exposure, as well as changes in white blood cell (WBC) levels, with statistical significance at p < 0.05. These results confirm the harmful effects of UVC radiation on the skin and blood, and reflect the relationship between exposure duration and biological changes, highlighting the importance of taking precautionary measures when using UVC radiation industrially.
