[en] In the present work some dosimetric characteristics of pellets of Brazilian silicates with Teflon as: actinolite-Teflon, tremolite-Teflon, rhodonite-Teflon and diopside-Teflon were investigated in gamma radiation beams of ⁶⁰Co using the thermally stimulated exoelectronic emission (TSEE) technique. The TSEE response reproducibility did not exceed 20%. The TSEE curves are simple, with a peak at 240 deg. C. The dose response curves show a sublinear behavior between 100 Gy and 20 kGy, and the lower detection limit for the pellets was (2.0±0.4)Gy. These results may be considered satisfactory for applications at high-dose dosimetry
