Abstract
- In recent years, the measurement of X-rays has attracted much attention. Especially in the aspects of environmental monitoring, radiation protection, and radiation therapy, to obtain more accurate measurement values, it is necessary to set up a corresponding reference device to trace the magnitude. This paper aims to establish a 350–450 kV wide spectrum and high air-kerma rate X-ray radiant mass. First, the Monte Carlo simulation was used to simulate the establishment of a model of the light engine, and the energy spectra of different tube voltages and different additional filters were calculated to obtain the average photon energy. Then the average photon energy was compared with the extrapolated average photon energy so that the deviation was within ±5%. Finally, half-value measurements are made on additional filters that meet the requirements. [ABSTRACT FROM AUTHOR]
