Introduction: Glass phosphors are broadly used to determine patient doses in radiation diagnostic and radiotherapy because of their good features, the dose ranges of interest are approximately0.1 -100 mGy for clinical x-ray diagnostics, and 1-5Gy for radiotherapy. Materials and Methods: Borate silica glass samples were prepared using melt quenching technique, XRD analysis confirms that the glass system is amorphous (non- crystalline). TL properties of glass were investigated such as optimum concentration, heating rate, and annealing procedure. The optimum glass samples of 45ZnO-45B 2O3-10SiO2 are used as glass radiation dosimeter. The samples were irradiated using 6MeV and 6MV photon beams in adose range (0.5-4) Gy. Results and Discussion: There is single and wide thermoluminescence glow curve that offering with maximum intensity at about 165 oC. Linear dose-response behavior has been observed in this dose range for both irradiation electron and photon beam. Sensitivity and minimum detectable dose have been found. The sensitivity of 6MeV is 1.7 greater than the sensitivity of 6MV photon energy. Conclusions: The results point out that this glass has the potential to be used as an electron and photon radiation dosimeter.

Beam Damage

Over the past five years it has become evident that radiation damage provides the fundamental limit to the study of blomolecular structure by electron microscopy. In some special cases structural determinations at very low doses can be achieved through superposition techniques to study periodic (Unwin & Henderson, 1975) and nonperiodic (Saxton & Frank, 1977) specimens. In addition, protection methods such as glucose embedding (Unwin & Henderson, 1975) and maintenance of specimen hydration at low temperatures (Taylor & Glaeser, 1976) have also shown promise. Despite these successes, the basic nature of radiation damage in the electron microscope is far from clear. In general we cannot predict exactly how different structures will behave during electron Irradiation at high dose rates. Moreover, with the rapid rise of analytical electron microscopy over the last few years, nvicroscopists are becoming concerned with questions of compositional as well as structural integrity. It is important to measure changes in elemental composition arising from atom migration in or loss from the specimen as a result of electron bombardment.
