Results of the examination of the variety of dry plant extracts (Thyme extract, Celery seed extract, Artichoke extract, Citrus aurantium extract and others) by two different detection methods are described. Both PSL and TL methods are presented and discussed. Comparative study based on the analysis of the results obtained by thermoluminescence (TL) and photostimulated luminescence (PSL) measurements delivered the arguments that preselection of detection methods based on model studies is rational to be adapted in analytical laboratories specialized in the detection of irradiated foods.
