Description

technical field [0001] The invention relates to a simulation device, in particular to a simulation device for simulating human eye lens ray energy deposition. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, people pay more and more attention to their own quality of life and physical health. However, there are occupational hazards of radioactive substances in various types of work in various industries. Improper measures may cause pathological changes due to ionizing radiation irradiating the body. For example, the scope of radiology includes contrast-enhanced examinations of the digestive system, urinary system, blood vessels, and spinal cord, as well as general X-ray irradiation, magnetic resonance, and CT. These examinations and treatments provide the most effective basis for clinicians to make a clear diagnosis and effective treatment And guarantee, but the chances of cat...

Problems solved by technology

[0003] In order to protect the health of occupational personnel and assess the size and risk of radiation dose received, it is necessary to configure radiation monitoring devices in the workplace of radiation workers, and most of the existing radiation monitoring uses ionization chambers In the workplace that needs to be measured, since the head of the human body will scatter the rays in the radiation field to a certain extent, it is difficult to measure the dose of the eye lens more accurately by directly using the ionization chamber for measurement, and its simulation is not high. The accuracy of the measurement results is difficult to guarantee
