任何東西都能阻擋像伽馬射線這樣的核輻射。但區(qū)別在于阻擋能力。攔網(wǎng)能力主要由兩個(gè)方面決定
　　Anything can block nuclear radiation like gamma rays. But the difference is blocking power. Blocking capacity is mainly determined by two aspects
　　1)原子序數(shù)
　　1) Atomic number
　　2)材料的密度明顯，材料的密度越大，堵塞能力越強(qiáng)。這個(gè)結(jié)論也可以通過(guò)感覺(jué)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.
　　至于原子序數(shù)，一般原子序數(shù)越高，電阻越強(qiáng)。原因涉及到一些物理知識(shí)。
　　As for the atomic number, the higher the atomic number, the stronger the resistance. The reason involves some physical knowledge.
　　給你一個(gè)簡(jiǎn)短的介紹，希望你能理解。伽馬射線進(jìn)入材料后，一般主要產(chǎn)生光電效應(yīng)、康普頓效應(yīng)。這兩種效應(yīng)的可能性都與塊中的原子數(shù)有關(guān)，原子數(shù)越高，這種效應(yīng)發(fā)生的可能性越大。除了上述兩個(gè)因素外，它還與伽馬射線本身的能量有關(guān)。能量越高，光電效應(yīng)和康普頓效應(yīng)發(fā)生的可能性就越小。穿透性越強(qiáng)的伽馬射線。較弱的勢(shì)壘相當(dāng)于物質(zhì)。至于你的第二個(gè)問(wèn)題，“還有什么已知的東西可以阻擋或反射輻射嗎?”。

　　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?".
　　就像我上面說(shuō)的，任何東西都可以，只要有阻擋的能力就行。鉛的原子序數(shù)是82，是自然界中的。當(dāng)然，防止核輻射的能力更強(qiáng)。高于鉛的物質(zhì)更耐藥。不幸的是，這些物質(zhì)在地球上是稀有的，相對(duì)昂貴(例如，金的原子序數(shù)是79，鉍的原子序數(shù)是83)，而且，更糟糕的是，它們本身通常具有放射性。當(dāng)然，這不如用鉛來(lái)抵擋輻射好。濟(jì)南瑞天主要提供鉛板、鉛錠、鉛磚、防輻射鉛玻璃、防鉛板門(mén)、防鋇砂
　　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
