PROBLEM TO BE SOLVED: To eliminate moving a dubious object by holding an irradiation part body of an X-ray generator to a holding body in a manner to be movable up and down, moving the irradiation part body down over the holding body when the holding body is placed on the ground, and irradiating X rays from near a surface of the ground. SOLUTION: An X-ray generator 2 of an electronic linac type has a voltage capacity of, e.g. approximately 950 keV, and is provided with an irradiation part body 4, a holding body 5, a magnetron 6 and a power supply box and operator panel 7 separately from each other. The irradiation part body 4 is held to the holding body 5 in a manner to be movable up and down, can move down to near a ground surface, and preferably can irradiate X rays from within approximately 2 cm of the ground surface. When a body 10 to be inspected is left as a dubious object on a road, the X-ray generator 2 is set to one side of the body 10 and a line sensor type X-ray detector 3 is set to the other side. The irradiation part body 4 can independently move to near the ground surface, and therefore X rays can be radiated from near the ground surface. The need of manually moving and contacting the body 10 is eliminated accordingly.
