The additive dose method for dose estimation in irradiated oregano by thermoluminescence technique

Absorbed‐dose estimation and quality attributes of gamma‐irradiated fresh shiitake mushrooms

“…However, for quantitative identification results, a different approach from the ESR method is needed as TL analysis eliminates radiation‐induced luminescence signals (destructive technique) and the TL response is highly dependent upon mineral contamination (greatly variable) rather than the food matrix . Different approaches reported by D'Oca et al , were adopted with slight modifications and compared to estimate the original absorbed dose for the irradiated fresh mushrooms. Best‐dose estimation results were obtained by the ABD2 (Table ) where a linear fit was most appropriate, as no saturation was observed.…”

“…As TL analysis removed the TL signals, the results upon re‐irradiation were corrected by adding TL 1 intensity. TL 1 , TL 2 , and TL 3 , and TL 4 intensities were used to estimate absorbed doses using linear and polynomial expressions and the back‐extrapolation method , …”

Application of the EN 1788 European standard for the control of saffron, pepper and blends

“…Definitively, these uncontrolled parameters suppose a lack of accuracy and precision in dose evaluation. Nevertheless, in case of irradiation of the whole sample one could successfully employ the additive dose procedure to evaluate the given dose (D'Oca et al, 2007;D'Oca et al, 2009).…”

Detection of Irradiated Food and Evaluation of the Given Dose by Electron Spin Resonance, Thermoluminescence, and Gas Chromatographic/Mass Spectrometric Analysis

“…The weaknesses of the methods are: it lasts a few days; the high values of re-irradiation doses can induce saturation behavior and changes in sensitivity. To improve the method, calibration doses lower than 600 kGy have been successfully used (D'Oca et al, 2009b); this method has, however, the inconvenience that the European protocol cannot be applied, because the irradiation at 1 kGy is not carried out and the TL ratio needed for identification cannot be evaluated.…”
