Resumo
Several kinds of silicates have demonstrated their usefulness as radiation detectors for
high dose dosimetry. In this work, oyster shell powdered samples were tested for high
doses using the thermoluminescence (TL) and thermally stimulated exoelectron
emission (TSEE) techniques. Pellets were obtained from the oyster shell powder mixed
with Teflon followed by a sinterization process of thermal treatments of 300°C/30min
and 400°C/1.5h. The TL glow curves showed two peaks at 110 and 220°C, and in the
TSEE case, two peaks at 120 and 180°C. The main dosimetric properties were studied:
reproducibility, dose-response curves and lower detection limits. The preliminary
results showed the potential use of the studied material as radiation detectors.
