Multiple-power multiple-dosage accelerators, rapid examination systems and rapid examination methods thereof

摘要

The disclosure provides a multi-power multi-dosage accelerator. The multi-power multi-dosage accelerator comprises an electron gun configured to provide a first voltage of the electron gun and a second voltage of the electron gun, and an accelerating tube configured to generate a first X-ray having a first dosage and first power according to the first voltage of the electron gun and generate a second X-ray having a second dosage and second power according to the second voltage of the electron gun, wherein the first dosage is a dosage which can be accepted by human bodies and is much less than the second dosage, the first X-ray is used for inspecting a first area where a person is located, and the second X-ray is used for inspecting a second area where goods are located.
