    射线防护材料由射线吸收物质和载体材料所构成,射线防护材料包括:金属材料,通用的建筑材料,软质材料,透明材料,中子防护材料,下面给大家一一来介绍具体有哪些。
    Radiation protection materials are composed of radiation absorbing materials and carrier materials. Radiation protection materials include: metal materials, general building materials, soft materials, transparent materials, neutron protection materials. What are the specific materials?
    金属材料:如铅、铁、钨、铜等,原子序数高,密度大,防护性能好
    Metallic materials: such as lead, iron, tungsten, copper, etc., with high atomic number, large density and good protective properties.

    射线防护器材
    通用的建筑材料,如混凝土、砖、土、硫酸钡、射线防护板等
    General building materials such as concrete, brick, earth, barium sulfate, radiation protection board, etc.
    软质防护材料:铅橡胶、钨橡胶等
    Soft protective materials: lead rubber, tungsten rubber, etc.
    透明防护材料:铅玻璃、有机铅玻璃、水等
    Transparent protective materials: lead glass, organic lead glass, water, etc.
    中子防护材料:石蜡、水、聚乙烯、木板、硼砂等富含氢元素的材料
    Neutron protective materials: materials rich in hydrogen, such as paraffin, water, polyethylene, wood, borax, etc.
    从上面介绍的防护材料来看,大部份材料都是以铅为主,具体的产品比如铅门、铅玻璃等,这是因为同其它金属材料比,铅具有很强的防腐蚀,耐酸碱,易加工,价格便宜等优点,从防护的角度看铅的原子序数大,密度大,能起到更好的射线屏蔽和阻挡的效果。所以选用铅做为射线防护是非常理想的材料,唯一不足的是铅本身对人体是有害的。
    From the above mentioned protective materials, most of the materials are mainly lead, specific products such as lead doors, lead glass, etc., this is because compared with other metal materials, lead has a strong corrosion resistance, acid and alkali resistance, easy processing, low price and other advantages, from the protection point of view of lead atomic number, density, energy. It has better effect of shielding and blocking. Therefore, the use of lead as a radiation protection material is very ideal, the only shortcoming is that lead itself is harmful to human body.
