    铅板能帮助人体抵挡多少辐射?
    来源: 发布时间:2020-01-06

      现在各医院的放射科、化工厂等处都有较大的辐射,铅板是他们的必备产品,一般采取屏蔽保护和距离保护两种原则。屏蔽是使用原子序数高的材料。在这里,我们经常使用铅板或含铅材料作为吸收不必要的x射线的材料。距离保护是指利用x射线照射量与距离平方成反比的原理,通过增加x射线源与人体的距离来减少照射量。通常从x射线管到人体的x射线,有一次射线和二次射线两种,二次射线是一次射线照射穿透其他物质的过程,其能量比一次射线小,影响较大。通常用x光管壳、遮光管和光圈、滤板、荧光屏后面的铅玻璃、铅屏、铅胶圈、铅手套和墙、来屏蔽保护。增加人体与x射线源之间的距离是一种简单而有效的距离保护方法。
      At present, the radiology department and chemical plant of each hospital have large radiation. Lead plate is their necessary product. Generally, shielding protection and distance protection are two principles. Shielding is a material with high atomic number. Here, we often use lead plates or lead-containing materials as the best materials to absorb unnecessary X-rays. Distance protection refers to the use of the principle that the X-ray exposure is inversely proportional to the square of the distance to reduce the exposure by increasing the distance between the X-ray source and the human body. Generally, there are two kinds of X-ray from X-ray tube to human body, one is primary ray and the other is secondary ray. Secondary ray is the process of primary ray penetrating other substances, its energy is smaller than primary ray, and its influence is greater. Generally, X-ray tube shell, light shielding tube and diaphragm, filter plate, lead glass behind the fluorescent screen, lead screen, lead rubber ring, lead gloves and walls are used for shielding protection. Increasing the distance between human body and X-ray source is a simple and effective distance protection method.
      更有效的射线防护材料主要有两种:一种是铅板,一种是硫酸钡。
      There are two kinds of most effective radiation protection materials: one is lead plate, the other is barium sulfate.
    射线防护器材
      铅板是指由金属铅轧制而成的板。铅板具有较强的耐腐蚀、耐酸碱、耐酸环境施工、医用辐射防护、x射线室、CT室辐射防护、重量、隔音等诸多方面,那么铅板辐射防护的原理是什么呢?
      Lead plate refers to the plate rolled from metal lead. Lead plate has strong corrosion resistance, acid and alkali resistance, acid resistant environment construction, medical radiation protection, X-ray room, CT room radiation protection, weight, sound insulation and many other aspects, so what is the principle of lead plate radiation protection?
      1. 穿透力弱,一张纸就能堵住;铅板可完全阻挡,保护辐射焦点不被误食,污染皮肤。
      1. The penetration is weak, and a piece of paper can be blocked; the lead plate can be completely blocked to protect the radiation focus from being eaten by mistake and polluting the skin.
      2. 线、介质穿透性强,一般铅板可以阻挡绝大多数射线,但通常在保护射线时加一层较低的原子序数屏障,以免产生轫致辐射。
      2. The wire and medium have strong penetrability. Generally, the lead plate can block most of the rays, but a lower atomic number barrier is usually added to protect the rays to avoid bremsstrahlung.
      一定厚度的铅板可以阻挡一定比例的辐射强度,辐射强度随铅板厚度的增加呈指数递减,理论上不可能完全阻挡。
      A certain thickness of lead plate can block a certain proportion of radiation intensity. The radiation intensity decreases exponentially with the increase of the thickness of lead plate, which is impossible to block completely in theory.
