Ray radiation and neutron radiation protection material and preparation method thereof

Abstract

The invention relates to the technical field of anti-radiation materials. The invention further discloses a ray radiation and neutron radiation protection material. The material comprises 20-30 partsof synthetic polyester, 5-8 parts of barium powder, 4-6 parts of bismuth borate, 4-8 parts of tungsten ore powder, 2-4 parts of barium sulfate, 10-16 parts of resin, 8-10 parts of tungsten ore powder,4-8 parts of a light element material, 2-4 parts of a lithium-containing material, 4-6 parts of boric acid, 6-10 parts of modified silicone rubber and 3-5 parts of an adhesive. Heavy elements of barium powder, tungsten ore powder and lead powder are arranged, according to the present invention, by arranging the light element material and the lithium-containing material, the slow neutrons can be well absorbed so as to achieve the good neutron protection effect, such that the good protection effect on the ray radiation and the neutron radiation is provided, and the good radiation resistance isprovided.

Description

technical field [0001] The invention relates to the technical field of radiation protection materials, in particular to a ray radiation and neutron radiation protection material and a preparation method thereof. Background technique [0002] X-rays are a photon flow produced by high-speed electrons hitting solids. Usually X-rays are generated by ray devices, and some devices that generate electron beams also generate certain X-rays. X-rays include bremsstrahlung and marking radiation. Neutrons are mainly produced by nuclear reactions, and their mass is slightly greater than that of protons. Neutrons are uncharged, and free neutrons are stable. Its half-life is about 11.0 minutes, and it undergoes β-decay with a maximum energy of 0.785 MeV. Using a radioactive source and a certain target substance, by means of (a, n) or (r, n) reaction, or hitting the target substance with high-energy particles in an accelerator, or fission of fissile substances in a reactor and some transura...

Problems solved by technology

[0003] Most people generally have weak awareness of protection against ray radiation and neutron radiation. The protection of ray and neutron radiation plays a vital role in people's safety. In some places with high radiation, people generally wear protective clothing, but a single protection The effect will have great limitations, and it cannot meet the protection requirements of radiation radiation and neutron radiation at the same time, so we propose a radiation protection material for radiation radiation and neutron radiation and its preparation method
