The aim of this work is to evaluate the possibility to use double Single Aliquot Regeneration (dSAR) method on polymineral fine grain fractions extracted from historical mortars for Optically Stimulated Luminescence (OSL) dating. The studied samples were collected from the church of Notre Dame de la Place (Bordeaux, France) and from the Saint-Jean Baptiste chapel (Périgueux, France). The research work was aimed at identifying the best experimental conditions related to the InfraRed stimulation time and the Preheating temperature value for a more accurate and precise dosimetric measurements. The results show the fundamental importance of these dosimetric tests for the Equivalent Dose (ED) evaluation.
