Abstract
The use of rare earths (TR) as dopant of materials has supplied the development of advance materials for many applications such as optical markers, special alloys, semiconductors, as well as radiation dosimetry. The doped rare earth calcium sulfate (CaSO4:TR) is the most studied, and CaSO4:Dy is used as thermoluminescent dosimeters for radiation dosimetry of beta, gama, X, electron, clini…
