ELECTRON PARAMAGNETIC RESONANCE SIGNAL IN WHEAT SEEDS INDUCED BY LOW-ENERGY ELECTRON BEAMS
Abstract and keywords
Abstract (English):
The use of radiation processing of food and agricultural products entails the need to control the values of the applied doses. This work shows the possibility of using EPR spectrometry for dosimetry monitoring of wheat samples irradiated at the URT-0.5 (0.5 MeV) electron accelerator. The general view of the spectra of the radiation-induced EPR signal is presented, its time kinetics is studied. The dependences of the EPR signal intensity on the value of the absorbed dose are obtained.
