| Abstract: | Nanocrystalline Ba0.97Ca0.03SO4
doped with Eu, was prepared by the chemical co-precipitation method. The
formation of the compounds was confirmed by XRD. The particle size was
calculated by the broadening of the XRD peaks using Scherrer’s formula. The
particle size was found to be around 45 nm. Samples in the form of pellets were
irradiated by 150 MeV proton beam. Thermoluminescence (TL) glow curves of the
irradiated samples were recorded and studied. It has been found that there is a
prominent TL glow peak at 498 K with a small shoulder at around 465 K. The TL
response is linear in the range 0.1-150 Gy and then saturates for higher doses.
The wider linear TL response of nanocrystalline Ba0.97Ca0.03SO4:
Eu and low fading makes it a good candidate as a dosimeter to be used for
detecting the doses of protons which are commonly being used in proton therapy
for the treatment of cancer. |
