DELGADO, J.A.; QUESADA, I.; MONTANO, L.M.  and  ANASAGASTI, L.. Safety of UV radiation for autofluorescence diagnosis of skin cancer. Rev. mex. fís. E [online]. 2006, vol.52, n.1, pp.78-83. ISSN 1870-3542.

It has been demonstrated that ex-vivo human skin autofluorescence is different for healthy and diseased tissue. In order to use these results for in vivo clinical applications, it is necessary to guarantee safe levels of UV radiation during skin scanning of patients and protect the eyes from scattered UV radiation coming from the skin surface. One of the goals of this work is to extend maximum limits of exposure to ultraviolet radiation in the spectral region between 315 and 400 nm. We also analyze irradiation levels of typical commercial ultraviolet LEDs and semiconductor lasers for application on skin cancer demarcation. Experimental measurements were not carried out in this paper.
