The main purpose of this work is the developing of sintered composites in order to allow their use as thermoluminescent dosimeters using a simple route to preparation, employing high temperature. The composites were prepared with CaSO4.2H2O doped with EuO3. Initially CaSO4.2H2O was dehydrated in oven at 100°C for 1h. After addition of dopants, glass and homogenization, PVA was incorporated into the compounds to make their compaction easier. The pellets with 6 mm of diameter and 1 mm thick were sintered at 750°C for 6 h. The TL emission curves showed two peaks when the samples were irradiated with beta source (90Sr+90Y) and X-ray. During calibration, TL responses were found to be proportional to the absorbed dose. The results showed that this material can potentially to be used in dosimetry. |
