Radiation protection equipment manufacturers suggest that the damage of radiation to human body is mainly due to the characteristics of X-ray - biological effects. After X-ray irradiation, a series of changes can take place in tissue cells and body fluids. The cells in tissue are inactivated by ionizing radiation, which causes radiation damage mainly in hematopoietic tissue.

X线从一发现就被用于医学检查。在计算机技术和射线探测器件飞速发展今天，X线影像检查设备日新月异。隔室摇控透视、胶片摄影、计算机断层摄影(CT)、计算机射线摄影(CR)、直接数字射线摄影(DR)、数字减影(DSA)介入手术检查等，都已成为医生临床诊断离不开的有效检查手段。与药物会有副作用一样，接受放射线检查时，被X线照射到的组织器官细胞，也会受到一定程度的伤害，但这种损害没有立竿见影的自我感觉。如果损伤轻微，人体自身的新陈代谢能将其修复，致病的可能性就很小。如果射线损伤较重，机体组织不能将其完全修复，就会导致致死性癌症或遗传性疾病的发生。

X-ray has been used for medical examination since its discovery. With the rapid development of computer technology and X-ray detectors, X-ray imaging equipment is changing with each passing day. The remote control fluoroscopy of compartment, film photography, computed tomography (CT), computed radiography (CR), direct digital radiography (DR), digital subtraction (DSA) and interventional surgery examination have all become effective means for doctors'clinical diagnosis. Like side effects of medication, cells of tissues and organs irradiated by X-rays may also be harmed to a certain extent, but this damage has no immediate self-perception. If the damage is mild and the body's own metabolism can repair it, the possibility of disease is very small. If the radiation damage is serious, the body tissues can not be completely repaired, which will lead to fatal cancer or genetic diseases.

射线防护服

Radiation protective clothing

X线是电磁波的一种，是以光速直线传播，遇到人体或其他物品后，一部分被吸收，另一部分被散射。但只要它还有能量，被物质吸收前还会发生多次散射。因此，在给患者透视、拍片曝光时及曝光后的瞬间(微秒量级)，透视室或拍片室内在任何一个位置上都有X线照射。规范射线防护服X线检查操作，应是一室只有一位受检患者，其余人均在防护区内候诊。每个防护合格的机房内，射线防护服都应配有供受检者和陪诊家属使用的防护用品，机房门外应有警示灯，当“射线有害”、“灯亮勿入”、或“在工作中”等警示灯亮时，候诊者应在门外等候，或在室内防护区内候诊。

X-ray is a kind of electromagnetic wave. It travels in a straight line at the speed of light. When it encounters human body or other objects, one part is absorbed and the other part is scattered. But as long as it has energy, multiple scattering will occur before it is absorbed by matter. Therefore, X-ray irradiation can be performed at any position in the fluoroscopy room or the photographic room at the time of exposure and at the moment after exposure (microsecond magnitude). To standardize the X-ray examination of radiation protective clothing, there should be only one patient in one room and the rest of them are waiting for treatment in the protective safety zone. In every qualified protection room, radiation protective clothing should be equipped with protective equipment for the use of the examinee and the accompanying family members. There should be warning lights outside the door of the room. When the warning lights such as "harmful radiation", "light is not allowed to enter" or "at work" are on, the waiting person should wait outside the door or in the indoor protective safety zone.
