| Resumo : | 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 100ºC 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 750ºC 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. |
