With the rapid development of science and technology, the use of radiation and isotopes in medical diagnosis and treatment is more and more extensive, and the diagnostic and treatment equipment of Radiology and nuclear medicine are updated more and more quickly. But the diagnosis and treatment of these radioactivity is a kind of destructive means. The construction technology is an important part of radiation protection, starting from the materials of radiation protection.
The mechanical equipment of radioactive source in the hospital includes: X-ray photography (photographing), fluoroscopy machine, gamma knife, CT machine, molybdenum palladium machine, dental film machine, i132, C-arm, electron accelerator, etc. These mechanical high-speed charged particles include alpha particles, beta particles, protons, and uncharged particles include neutrons, X-rays and gamma rays, which will cause harm to human body. Therefore, the use of radiation protection materials and radiation protection articles to prevent radiation harm is one of the important methods and effective means to protect human body.
Method / step
Radiation protection materials are made of various types and materials. It is very important to select high-quality radiation protection raw materials and experienced radiation protection engineering team for relevant decoration, whether it is public hospital radiology department or private dental hospital, dental clinic, pet hospital, X-ray room, CT room, Dr room, operating room, etc. mechanical equipment room with radiation source needs the third according to national requirements It can only be operated after passing the inspection of fangvocational Prevention Institute. In order to avoid unnecessary troubles caused by unqualified testing, it is better to choose better radiation proof raw materials and experienced radiation proof engineering construction team. Generally, companies that do radiation proof materials or radiation proof engineering have test reports of raw materials and review them once a year. This can be referred to when purchasing relevant radiation proof materials. Commonly used anti radiation materials are: lead plate, barium sulfate, lead door, lead glass, lead screen, lead room, lead box, lead rubber, anti radiation clothing, etc.
The radiation protection building design should be paid attention to in the radiation protection decoration of the hospital. The decoration of six walls, doors and windows in the equipment room of the radiology department is an important radiation protection project. Note: the area of the machine room shall not be less than 24 square meters for ordinary X-ray machines (including radiography, fluoroscopy, Cr, Dr, gastrointestinal), 36 square meters for double bed double tube machines, and 30 square meters for CT machine room. The wall uses 24 brick wall (the wall is coated with composite protective materials such as sulfuric acid barium sand concrete) or 37 brick wall, and the floor can be protected in the same way (if it is the lowest floor, radiation protection can no longer be applied). If the area of CT machine room is enough, 37 brick walls shall be used for walls, and barium sulfate concrete or lead plate shall be used for radiation protection for roof. The amount of lead equivalent needed to be done in various computer rooms is determined by the kilovolt emitted by the radioactive source.
The main material for anti radiation treatment of wall - barium sulfate protective coating is mainly composed of barium sulfate, also known as barite, which is a very good protective material for high-energy ray protection. It is an important barium bearing mineral, with the advantages of strong chemical inertia, good stability, acid and alkali resistance, large density, moderate hardness, high specific gravity, high whiteness, and the ability to absorb harmful rays (X-ray and y-ray), It has glass luster, non-magnetic and non-toxic. Barium sulfate has the advantages of strong chemical inertia, good stability, acid and alkali resistance, moderate hardness, high specific gravity, high whiteness, and can absorb harmful rays. It is a kind of material with environmental protection function, which has the advantages of multiple low, convenient construction and long service life. Barium sulfate has the performance of absorbing X-rays. Barium sulfate cement mortar is a kind of The content of BaSO4 should be no less than 80%. Barite is used to make barium cement, barite mortar and barite concrete, instead of metal lead plate to shield nuclear reactor and build scientific research, hospital radiology, Stomatology, X-ray room, CT room, Dr room, pet hospital, industrial nuclear radiation X-ray proof building and door protection: it is made of a special density plate and lead plate, stainless steel or aluminum plastic plate that can prevent radiation. The door is called lead door, lead plate door, radiation proof door, ray protection door, ray shielding door, which is divided into manual open type and electric push-pull type. The lead protection doors produced by regular manufacturers are generally made by one-time machine pressing, while some informal small workshops press the lead plate and density plate together by hand, so in the process of pressing, the lead plate and density plate are not firmly pasted, and the lead plate on the density plate is uneven, which will directly affect the protection of the lead protection door against radiation, and in the later stage Lead protective door may sink after being used for a period of time. There are also lead protection doors, which belong to special protection doors. Different from our household doors, the weight of lead protection doors is relatively heavy. Therefore, when installing, it needs a very professional and experienced master to install them. Otherwise, it is easy to cause many problems such as door deformation, sinking, open stuffing and so on. Window protection: a special type of glass (lead glass) is used for the radiation protection observation window of the equipment room or industrial flaw detection in the radiology department of the hospital. There are many specifications of lead glass. The specific specifications to be used should be determined according to the kilovolt emitted by the radiation source in the radiology room.
