EFFECT OF HEATING RATE ON NONLINEARITY OF DOSE RESPONSE IN TL BY KINETICS MODEL

EFFECT OF HEATING RATE ON NONLINEARITY OF DOSE RESPONSE IN TL BY KINETICS MODEL 1 corresp first-author Department of Physics,Zhongshan University, Guangzhou 510275, China Department of Physics,Zhongshan University, Guangzhou 510275, China 1 Department of Physics and Materials Science, City Polytechnic of Hong Kong Department of Physics and Materials Science, City Polytechnic of Hong Kong The general-order kinetics model of thermoluminescence is used to study the effect of heating rate on the nonlinearity of dose response in thermoluminescence. The results show that when we consider the dose dependence of the maximum intensity of the glow peak, the effect of the heating process on dose response is supralinear when the order of kinetics b > 1, and this effect is enhanced with the increase in heating rate.
