Title: Nanocrystalline BaSO{sub 4}:Eu For Dosimetry of Proton Beams

Abstract

Nanocrystalline BaSO{sub 4} doped with Eu, was prepared by the Chemical Co-precipitation method. The particle size was calculated by the broadening of the XRD peaks using Scherrer's formula with particle size around 45 nm. Samples in the form of pellets were irradiated by 150 MeV proton beam with dose range of 0.1 Gy to 325 Gy. Thermoluminescence (TL) glow curves of the irradiated samples were recorded and studied. It has been found that there are two prominent TL glow peaks at 460 K and 495 K. The TL response is sublinear below 1 Gy, linear in the range 1 Gy to 200 Gy and then becomes supralinear for higher doses. The wider linear TL response of nanocrystalline BaSO{sub 4}:Eu and low fading makes it a superior candidate as a dosimeter to be used for detecting the doses of protons for its various applications in the field of space, therapy and research.
