Abstract

The gamma ray radiator includes casing, outer shielding block, inner shielding block, source switch, small screw bolt on the outer shielding block, one set of radioactive sources in fan distribution aligned to the collimator and installed in one end of the small screw bolt inserted into the inner shielding block, source switch inside the inner shielding block and with upper notch, and source switch track matching with the track holder in the casing to make the radioactive sources possess two positions of shield state and work state. The present invention uses U-238 as main shielding material and W-95 as auxiliary shielding material. The gamma ray radiator has small volume, light weight, cast iron casing to prevent the small dosage radiation of U-238 and base of the radiator. The present invention has translated source switch acting as the shielding door normally.

Description

technical field [0001] The invention relates to a gamma ray radiation device. Background technique [0002] Radiotherapy equipment requires high-dose radiation to treat functional diseases, but requires the equipment to be as small as possible, as light as possible, and as large as possible for the treatment space. Due to the traditional structure and shielding materials of the current radiation devices, they are generally bulky and heavy. Therefore, the miniaturization of radiation devices and the high dose of radioactive sources have become a problem that must be solved by existing equipment. Contents of the invention [0003] The object of the present invention is to provide a gamma ray radiation device, which can achieve small volume and light weight of the radiation device. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] According to this, the outer shielding block, inner shielding block and power switch...
