Description

Technical Field

[0001] The utility model relates to the technical field of nuclear radiation detection, in particular to an attenuation-suppressed equivalent penetration simulation device. Background Art

[0002] Nuclear accident emergency response scenarios are not only high-dose, high-radiation nuclear contaminated sites, but also have special disposal environments, diverse accident types, complex source term mechanisms, and transient and changeable situations. They are multidimensional, dynamic, and harsh. The use of real nuclear radiation sources has high thresholds and great difficulty in creation, and is prone to cause radiation hazards to personnel and the environment. Therefore, the use of equivalent construction technology is a feasible way to solve this problem.

[0003] α particle 、β particle 、c Rays are the three most common types of radioactive rays. They have different penetrating abilities in the same medium, so the variation of their radiation energy in the air with distance is also different. The type and thickness of shielding materials have a great impact on their attenuation effect. These differences are mainly determined by the physical properties of radiation and the atomic structure of shielding materials. Among them: α particle, α The particles are composed of two protons and two neutrons, with a charge of +2. They have a large mass and a high charge, resulting in a high interaction strength with matter. Usually, thick shielding materials are not required, and paper, skin, and even a few centimeters of air can effectively block α particle. β particle, β The particles are high-speed electrons or positrons with an electric charge of -1 or +1. β Particle penetration ability α Particles are strong, but c The rays are weak and require thicker shielding materials, such as plastic, glass or light metal. The thickness of the shield is usually between a few millimeters and a few centimeters. β As particles penetrate the material, they interact with the electrons, causing their energy to decay. The effectiveness of the shielding depends on the thickness and density of the material. c ray, c Rays are a type of high-energy electromagnetic radiation that has no mass or charge. c The penetrating power of the radiation is very strong, and it can penetrate several centimeters or even meters of concrete or metal. It is necessary to use high-density materials, such as lead or tungsten, to effectively shield it. The shielding thickness is usually thicker than the shielding β The particles are much thicker, c The rays interact with matter mainly through the photoelectric effect, Compton scattering and electron pair effect. High-density materials can absorb or scatter gamma rays, thereby reducing their energy.

[0004] In order to provide practical training for employees in the nuclear industry or radioactive working environment and enhance their understanding of shielding strategies, it is used for users to understand the physical principles of nuclear radiation shielding, the selection criteria of shielding materials, and experimental modes. Users can verify the realization of the expected attenuation effect by selecting shielding materials and shielding thickness, as well as composite shielding structures with multiple layers of different materials according to the type and energy of radiation and the required safety level.

[0005] Therefore, it is necessary to provide an attenuation-suppressed equivalent penetration simulation device that can simulate the radiation attenuation effects under different shielding materials and thicknesses for experimental and educational purposes, simulate the interaction between radiation and shielding materials without using real radioactive materials, and provide a safe and flexible attenuation-suppressed equivalent penetration simulation teaching and research tool.

[0008] Preferably, each shielding block is provided with a text prompt label, including information on the shielding material type and shielding thickness equivalent to the shielding block.

[0009] Preferably, the shielding blocks are made of shielding materials, and each shielding block corresponds to a shielding material selected from the group consisting of paper, leather, plastic, glass, aluminum, lead, tungsten, concrete, boron carbide, water, polyethylene, lead-bismuth eutectic, bismuth, and steel.
