(2012) ESR and TL studies of irradiated Anatolian laurel leaf (Laurus nobilis L.), Radiation Effects and Defects in Solids, Volume 167, 2012 - Issue 6, Pages 410-420 .1042-0150http://kurumsalarsiv.tenmak.gov.tr/handle/20.500.12878/253Laurel leaf (Laurus nobilis L.) samples originated from Turkey were analyzed by Electron Spin Resonance (ESR) and Thermoluminescence (TL) techniques before and after gamma irradiation. Unirradiated (control) loreal leaf samples exhibit a weak ESR singlet centered at g = 2.0020. Besides this central signal, two weak satellite signals situated about 3 mT left and right to it in radiation-induced spectra. The dose-response curve of the radiation-induced ESR signal at g = 2.0187 (the left satellite signal) was found to be described well by a power function.Variation of the left satellite ESR signal intensity of irradiated samples at room temperature with time in a long-term showed that cellulosic free radicals responsible from the ESR spectrum of loreal leaves were not stable but detectable still after 100 days. Annealing studies at four different temperatures were used to determine the kinetic behaviour and activation energy of the radiation-induced cellulosic free radicals responsible from the left satellite signal (g = 2.0187) in laurel leaves. TL measurements of the polymineral dust isolated from the laurel leaf samples allowed distinguishing between irradiated and unirradiated samples.enginfo:eu-repo/semantics/openAccessTLLaurel leafDefne yaprağıKineticsKinetikAnnealingTavlamaFood irradiationGıda ışınlamasıElectron spin resonance (ESR)Elektron spin rezonansı (ESR)article167410420Issue 6
