An intercomparison of glow curve analysis computer programs: Pt. 1

Thirteen different computer programs for glow curve analysis are compared. Eleven programs used a shape of the glow peak based on the Randall-Wilkins model, but a variety of different approximations for evaluating the peak shape was noticed. Twelve programs were able to reproduce the peak areas and activation energies of a synthetic glow curve according to the Randall-Wilkins model simulating a four peaks TLD-100 glow curve within 6.3%. Four programs of those twelve were able to reproduce the input values within 0.4%. Clear differences in performance between the programs are due to differences in approximations used in calculating the glow peak shape. (author)
