Problems solved by technology

Taking neutron shielding material and gamma ray shielding material as an example, adding 40% each, the total addition amount is 80%, which will greatly reduce the tensile strength, bending strength and softness of the material. In order to achieve better tensile strength, Bending strength and flexibility, the amount of shielding material added should not be very high, and high shielding efficiency cannot be achieved

Abstract

The invention discloses a multilayer radiation-protective glove, formed by overlapping gamma-ray shielding layers and neutron shielding layers; the gamma-ray shielding layers are made from, by weight: 40-60% of rubber latex, 5-10% of a compounding agent, and 30-70% of gamma-ray protective material by mixing and glove mold soaking, adding up to 100% by weight; the neutron shielding layers are made from, by weight: 40-60% of rubber latex, 5-10% of a compounding agent, and 30-70% of neutron protective material by mixing and glove mold soaking, adding up to 100% by weight. The invention also discloses a manufacture process of the multilayer radiation-protective glove. Comprehensive neutron and gamma-ray protection can be provided by the glove, and the glove is good in flexibility and suitable for wearing.

Description

technical field [0001] The invention relates to the field of radiation protection, in particular to the field of comprehensive protection products for gamma rays, X-rays and neutrons, and specifically refers to a multilayer radiation protection glove and a manufacturing process thereof. Background technique [0002] The research and processing of nuclear materials are usually carried out in places with complex radiation environments, where there may be various rays such as α, β, γ, X-rays and neutrons, and γ, X-rays and neutrons have strong penetrating power. Neutron sources are often accompanied by gamma radiation. For example, radionuclide neutron sources and reactor neutron sources are also gamma radiation sources, but their strengths are different. And when neutrons interact with targets, shielding materials and other objects, they will also produce captured gamma radiation. Therefore, it is necessary to consider the comprehensive protection of neutrons and gamma rays. ...
