    为什么铅可以阻挡核辐射?
    来源:http://www.apzhuoyou.com 发布时间:2019-12-30

      任何东西都能阻挡像伽马射线这样的核辐射。但区别在于阻挡能力。拦网能力主要由两个方面决定
      Anything can block nuclear radiation like gamma rays. But the difference is blocking power. Blocking capacity is mainly determined by two aspects
      1)原子序数
      1) Atomic number
      2)材料的密度明显,材料的密度越大,堵塞能力越强。这个结论也可以通过感觉得到。
      2) The density of the material is obvious, the higher the density of the material is, the stronger the plugging ability is. This conclusion can also be felt.
      至于原子序数,一般原子序数越高,电阻越强。原因涉及到一些物理知识。
      As for the atomic number, the higher the atomic number, the stronger the resistance. The reason involves some physical knowledge.
      给你一个简短的介绍,希望你能理解。伽马射线进入材料后,一般主要产生光电效应、康普顿效应。这两种效应的可能性都与块中的原子数有关,原子数越高,这种效应发生的可能性越大。除了上述两个因素外,它还与伽马射线本身的能量有关。能量越高,光电效应和康普顿效应发生的可能性就越小。穿透性越强的伽马射线。较弱的势垒相当于物质。至于你的第二个问题,“还有什么已知的东西可以阻挡或反射辐射吗?”。

      Give you a brief introduction, I hope you can understand. After the gamma ray enters the material, the photoelectric effect and Compton effect are mainly produced. The possibility of these two effects is related to the number of atoms in the block. The higher the number of atoms, the greater the possibility of this effect. In addition to the above two factors, it is also related to the energy of gamma ray itself. The higher the energy, the less likely the photoelectric effect and Compton effect will be. The more penetrating the gamma rays are. A weaker barrier is equivalent to matter. As for your second question, "is there anything else known to block or reflect radiation?".
      就像我上面说的,任何东西都可以,只要有阻挡的能力就行。铅的原子序数是82,是自然界中的。当然,防止核辐射的能力更强。高于铅的物质更耐药。不幸的是,这些物质在地球上是稀有的,相对昂贵(例如,金的原子序数是79,铋的原子序数是83),而且,更糟糕的是,它们本身通常具有放射性。当然,这不如用铅来抵挡辐射好。济南瑞天主要提供铅板、铅锭、铅砖、防辐射铅玻璃、防铅板门、防钡砂
      As I said above, anything can be, as long as there is the ability to block it. The atomic number of lead is 82, which is the highest in nature. Of course, the ability to prevent nuclear radiation is stronger. Substances higher than lead are more resistant. Unfortunately, these materials are rare and relatively expensive on earth (for example, gold has an atomic number of 79, bismuth has an atomic number of 83), and, worst of all, they are usually radioactive in themselves. Of course, it's not as good as using lead to protect against radiation. Jinan Ruitian mainly provides lead plate, lead ingot, lead brick, radiation proof lead glass, lead plate door and barium sand
