Dose dependence and fading effect of the thermoluminescence signals in γ-irradiated paprika

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

“…Subsequent centrifugation showed clearly two different layers, the organic matter floating and the inorganic material at the bottom of the beaker. The two parts were separated by decantation and the mineral phase was washed several times using CCl 4 in every case (Correcher, Muniz, & Gomez-Ros, 1998). Finally, the samples were dried and stored at room temperature in a desiccator with silica gel in presence of sunlight.…”

Luminescence characterization of a sodium-rich feldspar

“…Both radioluminescence (RL) and thermoluminescence (TL) emissions from mineral phases are usually employed in luminescence dating [1,2], retrospective dosimetry [3], material characterization [4] and detection of irradiated food [5]. Among them, quartz and feldspars are suitable materials, since they exhibit (i) sensitivity to radiation, (ii) high reproducibility of the luminescence response, (iii) good dose-luminescence linearity in the ranges of interest (up to 100 Gy) and (iv) high stability of the luminescence signal after long time of storage [3].…”

Photostimulated luminescence detection and radiation effects on cinnamon (Cinnamomum zeylanicum) spice

“…Although several methods based on changes in chemical, biological and physical properties have been used in order to identify irradiated foods and in particular on cinnamon spice too (Calucci et al, 2003;Murcia et al, 2004;Arvanitoyannis, 2010;Jeong et al, 2014), in this work the thermoluminescence (TL) and photostimulated luminescence (PSL) methods, which are two of the most reliable methods, were employed (Correcher et al, 1998;Sanderson et al, 1989;Khan and Bhatti, 1999;Sanderson et al, 1995). On one hand, the TL is a sensible physical method to radiation detection and it is widely used due to its high precision (EN 1788(EN , 2001.…”
