ResumoAbsolute datings by luminescence of crystals are successfully used in Quaternary deposits by many researchers in different countries. Nevertheless, these methods are still used few times in Brazil and even are unbelieved by some research groups. The luminescence dating methods are based in theory of interaction of ionizing radiations with the matter, and the age of the sample to be dated is calculated from the concentration of defects induced by ionizing radiations in the matter. For the first time, incident cosmic radiation data measured in Brazil are presented, which are important in age determinations made by these methods. The methodology and interpretation of luminescence data are clearly presented in this paper to help the diffusion of usefulness of these methods.
