Abstract

The invention discloses a high-dose yield circumferential irradiation ray tube which comprises a cylindrical supporting base, a plurality of cooling pipelines are arranged at the outer side of the supporting base, a circle of radiation conversion target is arranged at the inner side of the supporting base, and a charged particle emitter assembly and a high-voltage socket are further arranged in the radiation conversion target. A charged particle beam fairing is arranged at the upper end of the charged particle emitter assembly, a shielding fairing is arranged at the lower end of the charged particle emitter assembly, and the high-voltage socket is located between the charged particle emitter assembly and the shielding fairing. By means of the above structures, an irradiation source which is high in dose yield, large in radiation angle, good in radiation uniformity, long in service life and compact in structure can be obtained, a radioactive isotope source is replaced, the hidden dangerof radioactive substance leakage is eliminated, meanwhile, good mobility is achieved, and application of irradiation processing is popularized.

Description

technical field [0001] The invention relates to the technical field of ionizing radiation irradiation equipment, in particular to a high-dose yield circumferential radiation irradiation tube. Background technique [0002] Irradiation processing is to use the physical and biochemical effects produced by the interaction of rays and substances to process substances to achieve the desired goals. At present, irradiation has been applied in a wide range of fields, covering food processing, biological experiment irradiation, material modification, vaccine production, medical equipment sterilization and blood irradiation, etc., which not only promotes scientific research but also achieves great social benefits. economic benefits. [0003] Traditional sources of radiation include radioisotopes and high-energy electron accelerators. Commonly used radioactive isotope sources for irradiation are cobalt source and cesium source, and the activity is generally several thousand to tens of...
