Resumo
The dosimetric properties of sand from Brazilian beaches have shown to be useful for high-dose dosimetry. The thermoluminescent (TL) and electron paramagnetic resonance (EPR) techniques were utilised, and the sand samples were recently studied
in relation to their main dosimetric properties. The EPR signal at g = 1.999 grows significantly in function of the absorbed
dose, and the TL peaks appear at 110 and 170ºC. However, these sand samples present a post-irradiation thermal decay at
room temperature, which is a problem for dosimetric procedures. In this study, sand samples have been studied in relation to
different thermal treatments. Post-irradiation treatments were performed at 50ºC up to 230ºC.
