چکیده انگلیسی
This research describes preliminary investigation of some radiation dosimetry characteristics of commercial dysprosium fluoride powder. The as-received aliquot has strong thermoluminescence (TL) emission with one sharp peak at â¼234 °C. The TL characteristics have been examined under excitation of gamma (γ) doses in the range 1 Gy-50 kGy from a 60Co gamma source. The dose response was linear up to 100 Gy and a sub-linear response was observed at higher doses. The TL signal is observed to remain stable for aliquots irradiated to γ-doses in the range 1-10 Gy over one month storage period in dark at ambient temperature and humidity conditions. This paper recommends using DyF3 in doping of TL materials which may be promising for future dosimeter development.
