Description
The purpose of this study was the dosimetric evaluation of thermoluminescent detectors of calcium sulphate doped with dysprosium (CaSO4:Dy) produced by IPEN compared to the TL response of lithium fluoride doped with magnesium and titanium (LiF:Mg,Ti) dosimeters and microdosimeters produced by Harshaw Chemical Company to clinical photon beams dosimetry (6 and 15 MV) using liquid water and PMMA phantoms. - Highlights: ► Dosimetric study of thermoluminescent detectors of CaSO4:Dy, LiF:Mg,Ti and μLiF:Mg,Ti. ► Clinical (6 and 15 MV) photon beams dosimetry using liquid water and PMMA phantom. ► Linear behavior to the dose range (0.1 to 5 Gy). ► TL response reproducibility better than ±4.34%. ► CaSO4:Dy represent a cheaper alternative to the TLD-100.
