铅玻璃里面含有铅，能够有效的防止辐射，所以多应用在医院等辐射较多的地方。铅玻璃虽然是含有氧化铅，但是其外表看起来是透明的。只是稍微发黄色，但是并不明显。防护玻璃一般指防X射线或γ射线或防中子的玻璃。由于物质对放射性辐射的吸收能力随其含有的金属元素的原子序数的增大而提高，所以防护玻璃都含有较多量的重金属氧化物。例如防X射线玻璃含较多量的PbO、BaO等，防γ射线的玻璃含较多量的PbO、WO3、Bi2O3等。由于γ射线的穿透能力较X射线强得多，所以γ射线防护玻璃的比重和铅当量较X射线防护玻璃高得多。
Lead glass contains lead, which can effectively prevent radiation, so it is widely used in hospitals and other places with more radiation. Although lead glass contains lead oxide, its appearance is transparent. It's just a little yellow, but it's not obvious. Protective glass generally refers to X-ray or gamma ray or neutron proof glass. As the absorption capacity of materials to radioactive radiation increases with the increase of the atomic number of metal elements, the protective glass contains more heavy metal oxides. For example, X-ray resistant glass contains more PbO, Bao, etc., and gamma ray resistant glass contains more PbO, WO3, Bi2O3, etc. Because the penetrating ability of gamma ray is much stronger than that of X ray, the specific gravity and lead equivalent of gamma ray protective glass are much higher than that of X ray protective glass.
和普通玻璃相差不大。对于医院放射科的观察窗来说，用的是我们的ZF3型号铅玻璃，其每毫米含铅量为0.22，但是对于核电站的ZF6或者ZF7来说，由于含铅量高，其颜色也是黄色比较深。
It's similar to ordinary glass. For the observation window of the radiology department of the hospital, our zf3 lead glass is used, and its lead content per millimeter is 0.22. However, for ZF6 or ZF7 of the nuclear power plant, due to its high lead content, its color is also dark yellow.
铅玻璃的主要性能在光学上是清楚的、透明的防护屏蔽而使用的一种具有规定衰减性能的低光学质量的防护玻璃板,其衰减性能每一毫米为0.22mmpb。医用铅玻璃表面涂敷涂料当时，绝关于来说把金属表和条件隔开了，这种维护效果可称为屏障效果。
The main performance of lead glass is clear and transparent protection shield optically. A kind of low optical quality protection glass plate with specified attenuation performance is used, and its attenuation performance is 0.22mmpb per millimeter. When the coating was applied on the surface of medical lead glass, the metal surface was separated from the condition. This kind of maintenance effect can be called barrier effect.
一般玻璃受γ射线辐照后，玻璃着色，透光度显著下降。着色程度跟玻璃的组成和结构有关，也跟辐照剂量有关。玻璃的这种特性，叫做辐照稳定性。高铅玻璃的辐照稳定性较差，辐照着色效应比较明显。但辐照停止后，放置一段时间，颜色可以逐渐消退。如将玻璃加热处理，则褪色作用进行很快，玻璃仍可重复使用。另外，为了提高玻璃的辐照稳定性，可以在玻璃中引入少量CeO2，这样的玻璃受辐照后，透光度下降较小。
After the general glass is irradiated by gamma ray, the glass is colored and the light transmittance decreases significantly. The degree of coloring is related to the composition and structure of the glass, and also to the radiation dose. This property of glass is called irradiation stability. The irradiation stability of high lead glass is poor, and the irradiation coloring effect is obvious. But after the irradiation stopped, the color could fade gradually after a period of time. If the glass is heated, the fading effect will be fast and the glass can be reused. In addition, in order to improve the irradiation stability of the glass, a small amount of CeO2 can be introduced into the glass. After irradiation, the transmittance of the glass decreases slightly.
