Embodiment 1

[0036] Such as figure 1 As shown, the present invention provides a method for manufacturing a radiation shield, specifically comprising the following steps:

[0037] S10: Obtain a shielding index, and calculate a first manufacturing parameter of the smallest three-dimensional mosaic molded part based on the shielding index.

[0038] Wherein, the shielding index refers to the index value determined according to the radiation source for judging whether the shielding effect meets the requirements. The shielding index in this embodiment includes but not limited to contact dose rate and site dose rate.

[0039] Specifically, after the shielding index is acquired, the shielding index is calculated by shielding calculation software to obtain the first manufacturing parameter of the smallest three-dimensional mosaic molding. Wherein, the mosaic three-dimensional molded part refers to a three-dimensional molded part whose shape is similar to a mosaic. The first manufacturing paramet...

Embodiment 2

[0051] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that a radiation shield manufacturing device is provided, including:

[0052] The manufacturing parameter acquisition module 10 is configured to acquire the shielding index, and calculate the first manufacturing parameter of the smallest three-dimensional mosaic molding based on the shielding index.

[0053] The radiation shielding body to be verified generating module 20 is configured to make the smallest three-dimensional mosaic molding based on the first manufacturing parameters, and bond all the smallest three-dimensional mosaic moldings to form the radiation shielding body to be verified.

[0054] The verification module 30 of the radiation shielding body to be verified is used to verify whether the physical and mechanical properties of the radiation shielding body to be verified meet the preset conditions through calculation of physical and mechanical properties.

[0055] The cube...

Abstract

The invention provides a manufacturing method and device for a radiation shield. In the method, the use amount of a shielding material is reduced through smallest mosaic cube formed parts, the requirements for light weight and small size of the shield are met, and the shield can be conveniently manufactured through the 3D printing technology. Meanwhile, radiation streaming caused by combined installation of different shields is avoided, the manufacturing process of the shield is simplified, the manufacturing time of the shield is shortened, and the physical and mechanical properties of the shielding structure are improved.

Description

technical field [0001] The invention relates to the field of design and manufacture of a radiation shielding body, in particular to a method and device for manufacturing a radiation shielding body. Background technique [0002] Radiation shielding refers to a radiation protection technology that uses the interaction between radiation and matter to reduce the radiation level in a certain area, thereby reducing the exposure of people and the radiation damage of materials. At present, research on radiation shielding at home and abroad mainly focuses on the development of shielding materials and the optimization of shielding structures to improve the performance of radiation shielding. However, shielding materials and shielding structures have always been a major contradiction in the design and manufacture of radiation shielding bodies, and it is impossible to achieve While satisfying a good shielding effect, it can also have good physical and mechanical properties (hardness, to...
