Background/Methods: Transmission of 362 nm ultraviolet A radiation (UVA) through epithelium of oral mucosa and skin epidermis was compared in rat and man. The transmitted irradiance was measured by means of a radiometer. Results: In man, significantly ( P <0.01) greater transmittance (2.8‐fold) was observed in skin compared to buccal mucosa. In rat, no significant differences were found. Conclusion: In different species and different types of epitheliae, separate studies are needed for the evaluation of UVA transmission.
