    在医院或者科研部门的放射科都用--铅玻璃做为视察窗,是因为铅玻璃即防辐射又透明。那样铅玻璃的主要成分是什么?它又是怎样防辐射的呢?
    Lead glass is used as an inspection window in the radiology department of a hospital or scientific research department because it is both radiation-proof and transparent. What is the main ingredient of lead glass? How does it prevent radiation?
    铅玻璃防护采取屏蔽防护和距离防护原则。屏蔽防护是指使用原子序数较高的物质,常用铅或含铅的物质,作为屏障以吸收不必要的x线。距离防护是指利用x线曝射量与距离平方成反比这一原理,通过增加x线源与人体间距离以减少曝射量。
    Lead glass protection adopts shielding and distance protection principles. Shielding protection refers to the use of a substance with a higher atomic number, usually lead or lead-containing substances, as a barrier to absorb unnecessary x-rays. Distance protection refers to the use of the principle that X-ray exposure is inversely proportional to the square of the distance, by increasing the distance between the X-ray source and the human body to reduce the amount of exposure.
    射线穿透人体将产生一定的生物效应。若接触的x线量过多,超过容许曝射量,射线防护涂料工程量,就可能产生放射反应,甚至产生一定程度的放射损害。然而,如x线曝射量在允许范畴内,射线防护涂料施工,--铅玻璃正常影响极小。众人无须由于辐射而回绝必要的x光和ct审查,更无须为此连医院的放射科的区域都不敢进。

    射线防护器材
    Radiation penetrates the human body to produce certain biological effects. If too much X-ray exposure exceeds the allowable amount of exposure, the amount of radiation protection coating engineering, may produce radiation reaction, and even produce a certain degree of radiation damage. However, if X-ray exposure is within the allowable range, the normal effect of lead glass on the application of protective coating is minimal. People do not have to reject the necessary X-ray and CT examinations because of radiation, nor do they even dare to enter the radiation section of the hospital.
    射线防护涂料的主要成分为硫酸钡,硫酸钡也叫重晶石,是高能射线防护很好的防护材料,是一种重要的含钡矿物,具有化学惰性强、稳定性好、耐酸咸、密度大、硬度适中、高比重、高白度、能吸收有害射线(x射线和y射线)等优点,是一种具有环保功能的材料,具有成倍低,施工方便,使用寿命长等优点!
    Barium sulfate, also known as barite, is a good protective material for high-energy radiation protection. It is an important barium-bearing mineral with strong chemical inertia, good stability, acid and salt resistance, high density, moderate hardness, high specific gravity, high whiteness, and the ability to absorb harmful rays (x-ray and y-ray). Advantages, is a kind of environmental protection function of the material, with double low, convenient construction, long service life and other advantages!
    射线防护材料基本特点:
    The basic characteristics of radiation protection materials are:
    1、射线防护涂料有阻挡x射线的作用,而且又具有吸收散射线和轫致辐射之功能。
    1. The X-ray protective coating has the function of blocking X-ray and absorbing scattering rays and bremsstrahlung radiation.
    2、射线防护涂料施工简便、粘结牢靠、无腐、无毒、无味,不龟裂、不脱落,强度可达20年以上。
    2. The X-ray protective coatings are easy to apply, reliable, non-corrosive, non-toxic, tasteless, non-cracking, non-peeling, and have a strength of more than 20 years.
    3、射线防护涂料成本低、不需日后维护、物理性能稳定。
    3, the radiation protection coating is low in cost, no need for future maintenance, and stable in physical performance.
    4、射线防护涂料减少了辐射折反射和电离空气几率,从而有效降低散射强度和有害气体浓度。
    4. Radiation protection coating reduces the probability of radiation catadioptric reflection and ionizing air, thus effectively reducing the scattering intensity and harmful gas concentration.
