X-ray conversion target

Abstract

The present invention discloses an X-ray conversion target comprising a panel and a base. The middle parts of the panel and the base are provided with openings along the length directions. The openings between the panel and the base are fixedly provided with a bombardment plate. Through installing the X-ray conversion target under an accelerator scanning window, the X-ray conversion target is bombarded by electron beams, and thus an X ray is obtained. Since the X ray has high penetrability, when a penetration requirement can not be satisfied by electron accelerator electronic irradiation, an X-ray irradiation product is obtained through bombarding the X-ray conversion target by the electron beams, and existing cobalt-60 radioactive source irradiation can be replaced.

Description

technical field [0001] The invention relates to an X-ray conversion target, in particular to a conversion target for generating X-rays by high-energy electron beam bombardment, and belongs to the technical field of radiation processing. Background technique [0002] Electron accelerator irradiation in traditional technology uses high-energy electron irradiation products produced by electron accelerators to modify products. [0003] For high-density irradiated products, cobalt-60 radioactive isotopes are currently used. Cobalt-60 radioactive sources are widely used in almost all walks of life. In agriculture, they are often used for radiation breeding, stimulation of production, radiation control of pests and food Irradiation preservation and preservation, etc. However, as a radioactive isotope source, cobalt-60 has a half-life of 5.27 years, which means that the radioactive source is decaying regardless of whether it is in production or not. Therefore, the radioactive sourc...

AI Technical Summary

Problems solved by technology

However, as a radioactive isotope source, cobalt-60 has a half-life of 5.27 years, which means that the radioactive source is decaying regardless of whether it is in production or not. Therefore, the radioactive source must be recharged or increased every year to maintain the original irradiation capacity. , the current increase price is very expensive, almost more than 30% of the annual output value, the worse the benefit, the higher the cost

[0004] Cobalt-60 radioactive sources are prevented from being irradiated in the irradiation room in the form of source rods, blocks, etc. When not in use, the radioactive source is lowered down to the well by a lift, and a safe depth is ensured to ensure the personal safety of personnel entering the irradiation room. However, there have been many source card accidents in China due to elevator failures. Due to the radiation of the radiation source, personnel cannot directly repair it. The radiation source continuously radiates rays in the irradiation room, causing the product to be overheated and burned, and related facilities in the irradiation room burned. and other serious accidents

There have also been many incidents of loss of radioactive sources in China, causing considerable impact
