EPR studies of the free radical kinetics in γ-rays irradiated Pleurotus ostreatus oyster mushrooms

Identification and Characterization of Gamma‐Irradiated Dried Lentinus edodes Using ESR, SEM, and FTIR Analyses

“…The results showed a little effect up to 75 °C on radiation‐induced ESR signals (Figure 4); however, a drastic effect was observed for the samples treated at 100 °C providing a significant decline in the overall ESR signal intensity with complete eradication of radiation‐specific signals ( g = 20005 and g = 1.9911). Bercu and others (2011) also reported a decline in the ESR signal intensity following thermal treatment of irradiated Pleurotus ostreatus muhroom samples. Yordanov and Gancheva (2000) studying irradiated samples of plant origin, also experienced a significant decline in ESR signals upon heat treatment.…”

Detection of irradiated frog (Limnonectes macrodon) leg bones by multifrequency EPR spectroscopy

“…The numerical values of thus normalised spectrum amplitudes plotted versus the absorbed dose and reproduced in Fig. 5, are better described by a saturation exponential function (Bercu, Negut, and Duliu, 2011):…”

“…After each treatment, the sample was cooled in a metallic pot containing water and ice. More details concerning thermal treatment could be found in Bercu, Negut, and Duliu (2011). Thermal stability was investigated by an isothermal annealing at 100°C, the time of exposure increasing progressively to 75 min.…”
