Identification and Dosimetry of Irradiated Pistachio (pistacia Vera L.) Using EPR
Radiation effects and defects in solids(2022)
摘要
In the current study, the EPR signal of both gamma-irradiated shell and kernel of the pistachio is recorded and investigated. The spectrum properties, microwave power dependency of signal intensities, short- and long-term temporal dependencies, and other significant factors are studied. This investigation was done on how varying radiation doses (0-10 kGy) affected the reactions of pistachio shells and kernels. The time dependence of the radiation-induced signal intensity of pistachio showed that the maximum intensity reached about 98.75% and 67% of its original value for shells and kernels, respectively, after the first six hours. These results indicate that EPR is an effective tool for gamma-irradiated pistachio identification and dosimetry, whether employing pistachio shells or kernels.
