Simulation and measurement of X-ray scattered radiation in radiodiagnosis
Abstrak
This work aims to measure the scattered radiation energy spectrum and radiation dose at different positions during radiological diagnosis through the Monte Carlo simulation and experiment. The results show that the average energy of the scattered radiation energy spectrum increases with the increase of the tube voltage and decreases with the increase of the scattering angle, but it changes very little with the measuring distance. It is not unified for the scattered radiation distribution in the space around the water phantom at the same tube voltage, and the exposure to scattered radiation is greater on the side closer to the water phantom or the X-ray tube. This indicates that the radiation exposure is not unified for medical staff in the scattered radiation field. The scattering energy spectrum and dose distribution are helpful to evaluate the scattered radiation exposure and enhance the self-protection awareness of medical staff in practice.
