Testing Methods Selection for X-Ray Radiation Performance Index of Micro-Dose X-Ray Transmission Body Scanner

Abstract:

The public security industry standard “General technical requirements for micro-dose X-ray transmission body scanner” (GA 926-2011) was released in March 25, 2011 and was formally implemented in July 1, 2011.The X-ray radiation performance index of micro-dose X-ray transmission body scanner includes Dose Per Inspection and Leakage Radiation Rate. The standard requires that Dose Per Inspection should be tested by ionization dosimeter. However, it doesn't specify which kind of equipment should be used to test Leakage Radiation Rate, and only requires a high sensitivity dosimeter. Therefore it is necessary to synthetically consider numerical features and test accuracy requirements, select appropriate test methods and test equipments. Radiograph Method, Ionization Detection Method, Scintillation Detection Method and Semiconductor Detection Method are analysed and compared from the detection principle, the advantages and disadvantages, I onization C hamber D osimeter was selected to test Dose Per Inspection, Scintillation Detection Method was selected to test Leakage Radiation Rate.
