Radiation protection door manufacturing method and system

Abstract

The invention provides a radiation protection door manufacturing method and system. The method comprises the steps of (1), measuring the size of a pre-installed door body, preparing a substrate with the same size, uniformly placing nuclear radiation sensors on the substrate, and testing the nuclear radiation intensity of a pre-installation position of the door body; (2) calculating the lead wall thickness required by the corresponding position of each nuclear radiation sensor according to the nuclear radiation intensity information measured by the nuclear radiation sensors, and taking the leadwall thickness as thickness unit information; (3) completing virtual modeling of an added plate according to the thickness unit information, and constructing a mold corresponding to the added plate according to the virtual modeling of the added plate; and (4) manufacturing the added plate by using the mold, and combining the added plate with the substrate to form a radiation protection door. According to the radiation protection door manufacturing method and the system, the thickness specification of the protection door can be adjusted according to the actual density degree of radioactive rays in the environment, and accurate protection is achieved.

Description

Technical field [0001] The invention belongs to the technical field of radiation protection equipment, and specifically relates to a method and system for manufacturing a radiation protection door. Background technique [0002] Since its discovery, radioactive materials have been widely used in various fields, such as medicine, energy, or military industry. The transportation, production or storage of radioactive materials must be protected as a whole. Not only must the walls be able to prevent radiation leakage, but also the doors To be protected, large military units or radioactive material experimental laboratories must use protective doors to achieve the purpose of radiation isolation. The protective doors generally use very thick lead plates as materials, mainly because lead plates have radiation shielding effect. [0003] However, there is a problem in the long-term use of the protective door: Because the protective door is very heavy and has a large inertia, each time the d...

Problems solved by technology

[0003] However, there is a problem in the long-term use of the protective door: because the protective door is very heavy and has a large inertia, every time the door is opened or closed, it is easy to cause damage to the contact surface of the wall and the protective door, and it is difficult to close the door manually. Driven to close the door, there are some limitations in the way of use, the weight of the protective door is several tons, the stability of the protective door movement and the sealing of the protective door and the door frame are also very important, otherwise radiation leakage will easily occur, and the radiation protection effect will be great At a discount, the bottom of the current protective door uses rollers to contact the guide rail, but it cannot guarantee a good seal between the ground of the protective door and the surface of the guide rail

[0004] The current protective doors are basically solid thick lead plates. It is very difficult to transport the protective doors when leaving the factory, and different environments have different requirements for the thickness of the lead plates. Now the protective doors are shipped from the factory, the thickness cannot be changed, and the actual radiation in the environment cannot be changed. Adjust the thickness specification of the protective door according to the degree of density, and there are limitations in use
