Description
Technical Field
The invention relates to the field of radiation protection articles, in particular to medical radiation protection clothing.
Background
In recent years, with the continuous development of modern science and technology, various high-energy rays are widely applied to various fields of military, communication, medicine, daily life and the like, which directly results in the increase of the annual collective effective dose of radiation dose worldwide. However, the high-energy ray radiation with overdose can cause harm to human body, damage organs and tissues of human body, and serious diseases and death even result. For this reason, image quality and radiation safety protection are becoming more and more of a general concern, and radiation protection has become an integral part of modern medicine. In order to protect the health of various people, protective articles are needed to shield various rays and microwaves. In real life, many workplaces need to use a radiation field source, and the radiation field source can emit radioactive electromagnetic waves or particles in a ray form, such as X-rays, alpha rays, beta rays, gamma rays and the like, and some examination devices used in places such as radiology departments, operating rooms and the like of hospitals have the radiation field source. People working or moving in these places need to be protected to a certain extent, and the protection means adopted at present are generally that the people wear radiation protection clothing. The radiation-proof clothes on the market at present are mainly radiation-proof lead clothes, the patterns of the radiation-proof lead clothes are aprons, and the radiation-proof lead clothes which are made of lead which is one of the radiation-proof lead clothes is mainly used for shielding electromagnetic radiation, so that the radiation-proof lead clothes can protect medical staff working in a radiology department of a hospital, patients needing X-ray irradiation, laboratory staff, industrial radiation environment construction units and staff working in a nuclear industrial radiation environment. Of course, the application range of the radiation-proof lead garment is not limited, and if the radiation-proof lead garment is used as a pregnant woman radiation-proof garment, electromagnetic radiation is mainly shielded, so the radiation-proof lead garment is widely applied to workplaces with radioactive substances, and the lead-containing radiation-proof garment can prevent ionizing radiation.
Although the radiation protection clothing is made of metal fibers doped with lead, the formed radiation protection lead clothing can be as soft as common clothing because lead is the main material of the radiation protection clothing. However, because the density of lead is large, the unavoidable radiation-proof lead clothes are mostly heavy and have poor air permeability, and generally, if the lead clothes are worn by a patient or a accompanying person for a short time, the lead clothes can be overcome, but if the lead clothes are worn by medical staff or pregnant women for a long time, the lead clothes bear a certain load and have the defect of poor air permeability, so that the lead clothes are really uncomfortable to wear for a long time.
Currently, there are also some studies in the related industry on lead-free or lead-free X-ray radiation protection materials. For example, the radiation protection and nuclear safety medicine institute of Beijing university and Chinese disease prevention and control center cooperate to develop lead-free X-ray shielding rubber materials and protective clothing by using mixed lanthanoid elements and compounds thereof as shielding agents. Polypropylene is used as a matrix, powder containing lead and barium is used as a shielding agent, and after mixing granulation, the X-ray-proof composite fiber and the non-woven fabric are prepared by melt spinning, and the X-ray protective clothing is prepared by the method. The radiation-proof fabric and the whole body radiation protective clothing are developed by taking modified polyethylene and polyvinyl chloride as shielding fabrics and tantalum metal as a shielding interlayer between the two fabrics, wherein the A-type protective clothing can effectively protect X rays and Y rays, and the B-type protective clothing is provided with an inner layer and an outer layer and is made of lead-free radiation protective materials. Natural rubber, vulcanization inhibitor and 3 metal shielding materials (W, bi and Sn with particle size of 1.0-35 mu m) with different atomic numbers are adopted for common research by Hubei Hua strong science and technology Co-Ltd and China radiation protection institute, the materials are added into a mixing roll for mixing, rubber is filtered, the mixed rubber and sulfur are subjected to open mixing on an open mill and then are subjected to rubber discharging, and finally the mixed rubber is subjected to calendering molding on a three-roll calender to prepare the radiation protection composite material. Although the radiation-proof composite material is low in lead or lead-free, rare metal materials and various materials are basically used, and most of the X-ray protection materials at present depend on the materials to absorb X-rays so as to reduce transmission for protection in principle. The manufacturing cost is high, the manufacturing process is complex, and recycling is difficult, so that practical popularization and application are limited to a certain extent.
In view of the above, the present inventors have made intensive studies to solve the above-mentioned drawbacks of the prior art.
