Modification method suitable for electron accelerator equipment based on cobalt source radiation shielding device

Abstract

The invention provides a transformation method suitable for electron accelerator equipment based on a cobalt source radiation shielding device, comprising the following steps: Step (1): filling the cobalt source water well with building materials, and covering the cobalt source water well with the cobalt source Irradiation room; step (2): the electron accelerator is fixed, and the electron accelerator is fixedly installed on the cobalt source irradiation room or the cobalt source water well in the step (1), and a scanning window is installed at the free end of the electron accelerator ; Step (3): a transmission device is provided on the ground, the transmission device runs through the side wall of the cobalt source irradiation chamber, and the scanning window is aligned with the transmission device. The present invention utilizes the original cobalt The shielding function of the source irradiation device transforms it into the workplace of the electron accelerator, so that the original cobalt source irradiation enterprises can continue to engage in the irradiation processing industry, and solve the transformation problem of the cobalt source irradiation processing enterprises at the lowest cost. The problem of secondary utilization of the cobalt source irradiation device is solved.

Description

technical field [0001] The invention belongs to the technical field of transformation of radiation shielding devices, and in particular relates to a transformation method suitable for electron accelerator equipment based on cobalt source radiation shielding devices. Background technique [0002] The cobalt source radiation shielding device is a place for storing cobalt-60 radioactive sources. It is used to irradiate food, medicine, polymer materials, etc. to achieve the purpose of disinfection and material modification. It is made of steel bars and cement, which can achieve the effect of shielding the gamma rays of the cobalt-60 radioactive source. During use, because the cobalt-60 radioactive source continuously releases rays and decays continuously, the cobalt source irradiation factory needs to purchase it every one to two years. Cobalt-60 radioactive sources are supplemented. For the sake of safety, the supervision and approval of cobalt-60 radioactive sources by the env...

[0002] The cobalt source radiation shielding device is a place for storing cobalt-60 radioactive sources. It is used to irradiate food, medicine, polymer materials, etc. to achieve the purpose of disinfection and material modification. It is made of steel and cement, which can achieve the effect of shielding the gamma rays of the cobalt-60 radioactive source. During use, because the cobalt-60 radioactive source continuously releases rays and decays continuously, the cobalt source irradiation factory needs to purchase it every one to two years. Cobalt-60 radioactive sources are supplemented. For the sake of safety, the supervision and approval of cobalt-60 radioactive sources by the environmental protection department is becoming increasingly strict. In addition, some small and medium-sized cobalt source irradiation devices have certain safety hazards in the irradiation mechanical design. The purchase of cobalt-60 radioactive sources is subject to various restrictions, and even faces the situation of shutting down
