title: Transmission of UVA radiation through epithelium of oral mucosa and skin in rat and man.
abstract: 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.
  
  
  CONCLUSIONS
  In different species and different types of epitheliae, separate studies are needed for the evaluation of UVA transmission.
