چکیده انگلیسی
Thermoluminescence (TL) curve recorded after gamma-irradiation at room temperature of Mn2+Mn2+-doped MgF2MgF2 phosphor shows TL peaks at 91, 147, 200, 235 and 295∘C. The 147∘C peak was tentatively attributed to the F centres recombination with hole centres trapped in the neighbourhood of the Mn2+Mn2+ impurity. This peak shows a good stability (low fading) and has been used to characterise the TL phosphor dosimetric properties. TL dose dependence has shown a good linearity in the range from 0.2 to 10 mGy, which makes it suitable for personal and medical dosimetry. The TL curves recorded after gamma rays or particles irradiation are similar, which suggests the possibility to use the phosphor also for particle detection.
