x光机主要分为两类，一类是医用的，另外一类是旅游景点、车站、高铁站、快递物流的安检x光机，现在人们称之为行李x光安检机。那么两者有什么区别呢？这个x光机会有辐射危害吗？
X-ray machines are mainly divided into two categories, one is medical, the other is security X-ray machines for tourist attractions, stations, high-speed railway stations, express logistics. Now people call them baggage X-ray security machines. What is the difference between the two? Does this X-rays have radiation hazards?
安检的和医用的x光机原理相同
The security inspection is the same as that of the medical X-ray machine.
x光机不外乎三个部分，一个就是球管，发出x光放射源，x光穿过物质，才能看得到我们肉眼常规普通光线看不到的东西，一定要有球管或者x线。第二，就是要有高压变压器，高压变压器把一般的电压变成高压，然后就提供球管，去产生电子然后再产生x光，这是第二部分。第三部分就是控制器，就说我需要放多少的x光量，要有控制板，所有x光机都逃不出，不管是x光还是CT也一样，尽管它里面结构很复杂，它结构应该是一样的。
X-ray machine is no more than three parts, one is the tube, emits X-ray radiation source, X-ray through the material, in order to see what we can not see in the ordinary light of the naked eye, there must be a tube or x-ray. Secondly, there must be a high-voltage transformer. The high-voltage transformer transforms the general voltage into high-voltage, and then provides a spherical tube to generate electrons and then X-ray. This is the second part. The third part is the controller, that is, how much X-ray I need to put in, with a control board, all X-ray machines can not escape, whether it is X-ray or CT, although its internal structure is very complex, its structure should be the same.
安检x光机辐射量更小
The X-ray radiation of security inspection is smaller.
行李x光安检机的用法就是将行李放入x射线通道内，进行x射线物品，经过转换后将物品的形状和颜色呈现出来，检测完毕后，旅客再拿回自己的行李离开。对物品进行过机检查用的x光机是利用x射线穿过物体而获得x影像，通过计算机处理显示在电脑屏幕上，用以辨认图像、评估物件安全性。原理虽然与医院做人体x检查类似，但安检设备的剂量比人体照射的x光量要少。因为安检的X光机检测的是物品，人过的是安检门，所以安检时人是不被x光机穿透的。而医用x光机需要把人体照射一遍看得很清楚，辐射剂量更大。x射线行李包检查仪为Ⅲ类射线装置，属于低危险射线装置。因此大家不用担心行李x光安检机的辐射问题。
The use of the baggage X-ray security machine is to put the baggage into the X-ray channel, carry out X-ray items, after conversion, the shape and color of the items will be presented, after the detection, the passengers will take back their baggage and leave. The X-ray machine used for checking objects is to obtain X-ray images by X-ray passing through objects, which are processed and displayed on the computer screen to identify images and evaluate the security of objects. Although the principle is similar to that of human body X-ray examination in hospitals, the dosage of security equipment is less than that of human body X-ray. Because the X-ray machine of security inspection detects articles and people pass through security gates, people are not penetrated by X-ray machine during security inspection. The medical X-ray machine needs to irradiate the human body clearly, and the radiation dose is greater. The X ray baggage checker is a type III ray device. It belongs to a low risk radiation device. So you don't have to worry about the radiation problem of baggage X-ray machine.
