Abstract:

The research objective is to study the radiation dose quantification possibility of a cooled fish.

The researchers processed the bone tissue samples (BTS) of the cooled trout with ionizing radiation doses of 3, 9 and 10 kGy. They conducted studies using portable automated ESR spectrometer of the Labrador Expert X type, developed by LLC “Spektr” with the assistance of the Natural Sciences Institute of the Ural Federal University named after the first President of the Russian Federation B.N. Yeltsin. The developed determination technique of the radiation dose in bone tissue by calculating the amplitude, width and ESR spectrum peak area allows to calculate the radiation dose (permissible variation of the amplitude, width and signal area at the level of ± 4% and D > 1) for rainbow trout to a high degree of accuracy (P ≤ 0.05): while irradiating with the 3 kGy dose, the amplitude is 3.28 e-5, the width is 10,81 G, the peak area is 1,367 e-4; while irradiating with the 9 kGy dose, the amplitude is 4.29 e-5, the width is 8,6 G, the peak area is 1,380 ± 0,00083 e-4; while irradiating with the 10 kGy dose, the amplitude is 3.88 e-5, the width is 11,78 G, the peak area is 1,558 e-4.
