The Advanced Radiation Technology Institute (ARTI) introduced an electron beamaccelerator capable of continuous radiation processing in 2018. The instrument can be used forempirical research to industrialize already developed radiation technologies. Radiation processinghas minimum absorbed dose requirements and maximum absorbed dose limits. It is important forradiation accelerators to maintain constant values for the device̓s operating parameters to meetthe absorbed dose required by the product (AAPM 1998). Therefore, an inspection (PerformanceQualification) of the accelerator performance is required, and the operation values of all processesneed to be set so that the absorption dose requirements can be met. To maintain dose requirementsduring the process, the processing variables need to be controlled: electronic energy, beam current,and parameters according to material handling (transfer vehicle speed or survey time), beamwidth, and characteristics of the processing process and conditions of investigation. In this study,the performance test of the electron-ray accelerators presented by the international standards ofISO/ASTM was carried out. Assessments include Electron Beam Energy, Average Beam Current,Beam Size (Beam Spot Size), Spoken Size and Homogeneity (Scan Size and Uniformity of Unit), andMoving Dose Assessment (Uniformity). This allowed individual measurements to be obtained withinthe allowable range for each item specified in ISO/ASTM 51649. Periodic inspection procedures willneed to be established to maintain a constant dose for the devices.
