AN INTERCOMPARISON OF GLOW CURVE ANALYSIS COMPUTER-PROGRAMS .1. SYNTHETIC GLOW CURVES

Thirteen different computer programs for glow curve analysis are compa red. Eleven programs used a shape of the glow peak based on the Randal l-Wilkins model, but a variety of different approximations for evaluat ing the peak shape was noticed. Twelve programs were able to reproduce the peak areas and activation energies of a synthetic glow curve acco rding to the Randall-Wilkins model simulating a four peaks TLD-100 glo w curve within 6.3%. Four programs of those twelve were able to reprod uce the input values within 0.4%. Clear differences in performance bet ween the programs are due to differences in approximations used in cal culating the glow peak shape.
