Investigation of the effect of heating rate on the dose dependence of tl glow curves of Li2B4O7: Mn (TLD - 800)

In this study, the effect of the heating rate on the dose dependence of TL glow curves of Li2B4O7: Mn (TLD-800) have been investigated by using the supralinearity function, f(D). The dose response functions have been evaluated at different linear heating rates between 1 oC/s and 20 oC/s. The results of this study have showed that, the main peak shows high linear behaviour at linear heating rate of 3 oC/s and 4 oC/s. Also the peak temperatures of all peaks are shifted higher temperatures and the integrated peak area of the curves decreases by about 65 %. as the heating rate increases as expected in theory because of the thermal quenching effect.Keywords: Li2B4O7: Mn (TLD-800), f(D), thermal quenching.
