Abstract

Silica gels were prepared by the sol-gel method containing varying amounts of Fe. The gels were irradiated with γ-ray doses in the range from 0.3 to 11.5 kGy. The thermoluminescent response was characterized before and after irradiation. When the samples were irradiated in the range 0.3 to 1.0 kGy, no thermoluminescent response was detected. However, when the samples were irradiated in the range from 1.0 to 11.5 kGy, they showed a clear thermoluminescent behavior and a linear dose–response relationship over the whole irradiation range, opening up the possibility of employing this system as a radiation dosimeter.
