title: [Is accurate UVA dosimetry in photobiology and photodermatology an illusion?].
abstract: Accurate UVA dosimetry is of primary importance for photobiological research as well as for UVA phototherapy and photochemotherapy. For the former, it is necessary because the success or failure of an experiment can depend on the UVA dose, and for the latter, the carcinogenic risks are dependent upon the cumulative dosage, as is the evaluation of the therapy. Experience has shown that the UVA meters used in different photodermatological and photobiological centers give divergent values when exposed to the same UVA source. One Joule/cm2 does not seem to be the same thing everywhere, and it can vary by as much as 400 p. 100.
