The effect of heating rate on the dose dependence and thermoluminescence characteristics of CaSO4: Dy (TLD-900)
چکیده انگلیسی


• The effect of heating rate on the dose dependence of TLD-900 has been investigated by using f(D) function at different linear heating rates.
• The experimental results have shown that the linearity of the main dosimetric peak continues nearly up to 100 Gy at heating rates of 3 oC/s and 5 oC/s.
• The peak temperatures are shifted higher temperatures as the heating rate increases.
• The integrated peak area of the curves decreases by about 50% as the heating rate increases.

CaSO4: Dy (TLD-900) is a well-known phosphor for radiation dosimetry using thermoluminescence. In the given study, the effect of heating rate on the dose dependence and thermoluminescence characteristics of TLD-900 has been investigated by using the dose response function f(D) at different linear heating rates. It was observed that, the peak temperature of the main dosimetric glow peak (P2) shifts to higher temperature sides and the integrated peak area decreases by about 50% as the heating rate increases due to thermal quenching.
