Modeling and experimental research of the processes of radiation damage formation in the interaction of gamma quanta flows and relativistic electron beams with solution of organic dyes

TL;DR

This study models and experimentally investigates how gamma rays and electrons cause radiation damage in organic dye solutions, revealing that electrons are significantly more destructive than gamma quanta.

Contribution

The paper develops a model and conducts experiments to compare radiation damage effects of gamma rays and electrons on organic dye solutions.

Findings

Electrons cause four times more dye molecule destruction than gamma quanta.

Simulation and experimental results are consistent.

Electron passage through tungsten layers was effectively modeled.

Abstract

The processes of interaction of an aqueous solution of methylene blue (MB) organic dye ($C_{16}H_{18}N_{3}SCl$ ) with gamma quanta and electrons have been investigated. A model has been developed, and the passage of electrons with an energy of 15 MeV through tungsten layers with a thickness of 1...8 mm has been simulated. A number of experiments were carried out on the basis of the simulation results. Analysis of the calculated and experimental data showed that one incident electron destroys 4 times more dye molecules than one incident gamma-quantum.
