Resumo The CaSO4:Dy is a good thermoluminescent dosimeter because of its high sensitivity and low cost. With graphite in the pellets it is possible to reduce the energy dependence. the sensitivity and energy dependence of the different thicknesses of CaSO4:Dy pellets was studied with different amounts of graphite. the results have shown the optimal quantity of the graphite and the appropriate thickness of the pellets that can be used in dosimetry of beta field, photons or both simultaneously.
