This paper gives a full mathematical description of the kinetics expressions used in thermoluminescent isothermal decay experiments. The corresponding equations have been slightly modified considering the peak intensity at the maximum (I-M) instead of the peak area Phi as proportional to absorbed dose, given normally in isothermal decay equations. The isothermal decay method was applied to the principal glow peaks of two different phosphors: LiF:Mg,Cu,P+PTFE, using first- and second-order kinetics, and BaSO4:Eu + PTFE, using second-order kinetics.
