Dosimetric system on the basis of EPR-spectroscopy with use state primary standards of power of the absorbed dose and Standard of number of the paramagnetic centers

Abstract

This paper presents an overview of the current state of ensuring the measurement uniformity of absorbed dose of ionizing radiation during the treatment of food and agricultural products in Russia. The way of measuring the absorbed dose of ionizing radiation in the range of absorbed doses up to 1 kGy with Primary State Standard GET209-2014 and GET83-2017 is proposed.

Application of the electronic paramagnetic resonance method for detecting radiation-processed food products

“…The alanine dosimetry method is based on the fact that in a number of substances under the influence of radiation, paramagnetic centers are formed, the number of which depends on the radiation dose. The presence and number of such paramagnetic centers is established using electron paramagnetic resonance spectrometer (EPR spectrometers) -devices based on the phenomenon of electron paramagnetic resonance [8].…”
