摘要：
Brazilian fluorite-based dosimetric pellets were X irradiated at -170-degrees-C to record simultaneously TL and TSEE glow curves at a heating rate of 1-degrees-C per 6 s. A close relationship between TL and TSEE was observed for all the peaks from -170 to 400-degrees-C. The effect of high dose and high exposure rate on dosimetric pellets was studied by irradiating them with a 21 MeV electron beam from a linear accelerator. TL due to NaCl used as agglutinant arises for exposures equivalent to 2.58 kC.kg-1 in the form of a sharp glow peak at 225-degrees-C, when CaF2 glow peaks are saturated or decreasing due to radiation damage. Emission spectra of dosimetric pellets were obtained for three TL peaks in the range RT to 350-degrees-C. They are different from peak to peak, indicating that some trapping centres are spatially associated with recombination centres.
