Abstract

The invention provides a medical anti-radiation material. The anti-radiation material is of a multilayer structure and comprises an anti-radiation layer, a buffer layer and a protecting layer, wherein the anti-radiation layer is formed by melting and mixing fine lead-copper-alloy powder and coumarone resin; the buffer layer is produced by bamboo carbon fibers; the protecting layer is a textile material containing superfine zinc oxide particles. The medical anti-radiation material has the advantages that medical anti-radiation material has a good resisting effect on harmful radiation caused by radioactive treatment equipment and is good in anti-radiation effect due to the fact that radiation harm is resisted by various materials in a staged and graded manner, and the medical anti-radiation material is good in toughness and can be cut into an anti-radiation garment or can be used in diversified anti-radiation devices.

Description

technical field [0001] The invention relates to the technical field of medical radiation equipment protection, in particular to a medical radiation protection material. Background technique [0002] With the continuous improvement of medical testing technology and treatment technology, the diagnosis rate and treatment rate of some malignant diseases have been significantly improved, but the use of some radioactive instruments will also cause harm to normal tissues, such as when a patient goes to the hospital When seeing a doctor, performing diagnosis and development, such as receiving X-rays, CT, PET, isotope therapy and other equipment for diagnosis and receiving certain exposures, these radiations themselves are harmful to a certain extent, but the degree of harm is closely related to the frequency of use. For example, the radiation dose of a bone density examination is 1 microsievert (μSv), a chest X-ray is 100 microsieverts (μSv), a whole body CT is 10,000 microsieverts ...
