摘要： The disclosure provides a method for measuring X-ray energy of an accelerator in an inspection system. the method comprises: building a database comprising correspondence between half-value layer (HVL) and energy under a predetermined condition; measuring HVL for X-rays of the accelerator in the inspection system on line under the same predetermined condition; and comparing the measured HVL with the HVLs in the database comprising correspondence between HVL and energy to determine the X-ray energy of the accelerator. The method is applicable to a large-scale container/vehicle inspection system for measurement of X-ray energy/HVL of the accelerator so as to acquire source state of the inspection system in real time.
