摘要

The lead shield (1) of a betatron (2) in x-ray generator for x-ray test equipment for the safety checking of objects, comprises four shielding parts (7, 8, 9, 10), of which two parts are semi-cylindrically formed and are provided with recesses (11) in their lateral surfaces. The shielding parts with their lateral surfaces are arranged in corresponding recesses of the remaining shielding parts, so that the recesses in the lateral surfaces form air channels between the semi-cylindrical parts and the remaining parts. The lead shield (1) of a betatron (2) in x-ray generator for x-ray test equipment for the safety checking of objects, comprises four shielding parts (7, 8, 9, 10), of which two parts are semi-cylindrically formed and are provided with recesses (11) in their lateral surfaces. The shielding parts with their lateral surfaces are arranged in corresponding recesses of the remaining shielding parts, so that the recesses in the lateral surfaces form air channels between the semi-cylindrical parts and the remaining parts. The parts are formed and arranged to each other with regard to their cross section in rotational symmetrical manner. The air channels in two of the remaining parts connect the recesses in the lateral surfaces of the semi-cylindrical parts with the surroundings. The shielding part with their intersecting planes bears on opposite front sides of an external yoke of the betatron. The intersecting planes of the shielding parts are so large than the front sides of the external yoke. An independent claim is included for x-ray test equipment for the safety checking of objects.
