Investigation of dosimetric and thermoluminescence properties of CaF2:Mn (TLD-400)

The additive dose (AD), Tm(Ea)?Tstop, repeated initial rise (RIR), peak shape (PS), and computerized glow curve deconvolution (CGCD) methods were used to analyze the thermoluminescent (TL) dosimetric glow peak of CaF2:Mn after ß- irradiation between the dose level D=0.015 Gy and D=110 Gy. The activation energies found with the IR and PS methods yield very close values after the cleaning of low temperature satellite peaks from the dosimetric glow peak by increasing stopping temperature in the Tm?Tstop experiment. The influence of heating rates on the response of dosimetric glow peak of CaF2:Mn was also studied by the peak height and peak area methods using CGCD technique. It was observed that the peak intensities and total area of glow peak decrease continuously with increasing heating rate.Another dosimetric characteristic which is the dose response of this peak was also examined by peak height and area methods.
