Computerized glow curve deconvolution applied to high dose (102-105 Gy) TL dosimetry

First order kinetic analysis is applied in a computerized deconvolution technique to the thermoluminescence (TL) glow curve of LiF:Mg, Ti (TLD-100) over the dose range 1-105 Gy. The computer routine, based on a nonlinear least-squares method, is capable of simultaneously deconvoluting as many as eight overlapping glow peaks (24 independent parameters). The ability to separately follow the dose response of the high temperature glow peaks is shown to extend the usefulness of TL dosimetry to 105 Gy and beyond. (orig.)
