Descripción: Thermoluminescence (TL) sensitivity of natural quartz (beaches,paleobeaches and fixed dunes) to Beta and Gamma rays has been studied in a temperature range between 250400C, before and after bleaching by solar irradiation. A first TL glow growth curve was obtained through Beta irradiation of "as found" samples and a second glow growth curve was obtained by bleaching through solar irradiation the TL acquired either through an excitation Gamma dose or through environmental radiation to finally re-irradiate the samples under Beta rays. Experimental results showing the constancy of sensitivity, for doses of until about 10krads, are the basis for a proposal to improve TL dating methodology expanding its present limits.
