Animal organ radiation dose evaluation method for particle external irradiation experiment

Abstract

The invention relates to the field of radiation protection, and provides an animal organ radiation dose evaluation method for a particle external irradiation experiment. The method comprises the steps of obtaining an organ dose conversion factor by utilizing an experimental animal digital model and particle transportation simulation calculation, and then measuring air kerma kinetic energy to perform organ radiation dose evaluation. The problem that the organ dose is difficult to directly measure is solved, and the technical effect of improving organ dose evaluation convenience and accuracy is achieved.

Description

technical field [0001] The invention relates to the technical field of radiation protection, and relates to a method, a device, an electronic device and a computer-readable storage medium for evaluating the radiation dose of an animal organ in a particle external irradiation experiment. Background technique [0002] With the in-depth study of the biological effects of ionizing radiation, researchers have found that the average dose of the whole body cannot meet the needs of the evaluation of biological effects; and the relationship between the biological effects of ionizing radiation and the dose is an important theoretical basis for radiation protection, that is, the medical treatment of radiation damage. Therefore, researchers usually use experimental animals (mice, rats, monkeys, etc.) to study the relationship between organ radiation dose and biological effects under particle external irradiation conditions. However, since radiation detectors cannot be placed directly in...

Problems solved by technology

[0004] 1) It is necessary to make an equivalent phantom, which is time-consuming and laborious, and increases the cost of testing;

[0005] 2) The existing equivalent phantom has a simple geometric structure, which is only a cube or cylinder composed of a single substance (water or equivalent plastic), and there are no various organs and tissues in the phantom; therefore, the anatomical shape of each organ and tissue cannot be reflected The measurement results cannot accurately reflect the size and change law of the radiation dose of the organ;

[0006] 3) The measurement cycle is long and the measurement steps are cumbersome, resulting in low measurement efficiency
