Abstract:

In this study, the values of electron beam energy and dose parameters of a 10 MeV electron accelerator were measured and analyzed in detail in order to optimize the parameters used for equipment detection and improve the existing irradiation processing technology. First, the values of most probable energy and the average energy of the accelerator were estimated using the national standard aluminum lamination method. Then, the optimal penetration depth and depth dose distribution curves of the electron beam in four typical uniform materials of varying densities — PP (Polypropylene) plastic board, decorative low density board, PVC (polyvinyl chloride) foam board, and PVC acrylic board were measured and analyzed. The results demonstrated that the average energy of the electron beam was 9.42 MeV, which is slightly less than the most probable energy of 10.01 MeV, and it was concluded that the average energy is more suitable for the formulation of processing technology. Further, the dose uniformity ratio (DUR) was observed to be inversely proportional to the density of the medium, and their ratio values are 1.2, 1.28, 1.34, and 1.46 for the above four materials. it is opposite to gamma radiation situation. The relations between penetration depth and material density, and dose uniformity ratio and material density, were obtained via the empirical fitting method, which exhibit positive consequence with respect to the formulation and improvement of standardized irradiation processing.

Key words: Electron accelerator, Most probable energy, Average energy, Dose uniformity ratio
