射线危害是指射线对人体造成的危害。按照射方式，通常分为大剂量短时间急性照射和小剂量长期慢性照射，其出现在人体的损伤时间和症状程度各有不同。急性损伤一般早期即可表现出来，有些会经过一段较长的潜伏期。早期的射线效应有：造血器官损伤，消化系统损伤型和中枢神经损伤型三类，受照剂量自数百至数千拉德以上不等。射线的慢性损伤在判断上相当困难，因为受照与发现症状之间历时较长，其因果关系不易判明，此外，射线引起的自觉症状和他觉症状没有任何特异性。对受照个人必须收集到受照情况和当时症状等证据，以供合理评定。所以射线防护很有必要，下面为您分享一下医院走廊射线防护门的施工方案。

　　It is a kind of metallic lead and rolling plate, with anti-corrosion, strong acid and alkali resistance, with the development of science and technology, is widely used as the acid environment construction, medical radiation protection, X light, many aspects of radiation protection, CT room, add sound insulation, is a relatively cheap radiation proof materials. When we use it, to make good maintenance on it, so as to prolong its service life, improve work efficiency, so how to maintain it?

　　1、防止由于人体冲击防护铅板玻璃而造成的伤害，最根本最有效的方法是避免人体对铅玻璃的冲击。在防护铅板上作出醒目的标志以表明它的存在，或使人不易靠近铅玻璃，就可以从一定程度上达列这种目的。

　　1, to prevent due to human impact protective lead glass damage, the most fundamental is the most effective method to avoid the impact of human lead glass. Make eye-catching signs in the lead on the door to indicate that it exists, or is not easy to make people close to the lead glass, it can be to some extent darie for this purpose.

　　2、在防护铅板单侧或双侧应设置护栏或摆放放花盐等装饰，并且保护正面宽度不宜太小、太窄。竖直保护应对准铅玻璃中心，水平保护应位于最高临近地板以上800至1100mm的区域内。

　　2, unilateral or bilateral protection it should be set or placed flowers such as salt barrier protection and decoration, front width is too small, too narrow. Vertical protection shall be centered on quasi lead glass. Horizontal protection shall be located within 800 to 1100mm of the floor above the floor.

　　3、保护措施应能够使人警觉有防护铅板存在，又能阻挡人体对铅玻璃猛烈的冲击，同时又起到了装饰作用，并且随着防护铅板透光尺寸逐渐变大，保护设施应能承受的集中冲击力也要随之增强。

　　3, protective measures should be able to make people aware of the protective plate can prevent the impact of human existence, to lead glass fierce, also played a decorative role, and with the door lead light enlarging, centralized protection facilities should be able to withstand the impact force also increases.

　　4、保护设施个不得存在断裂和冲击造成的弯曲，不得松动、摇摆，当不能满足要求寸应及寸更换或维修。

　　4, protection facilities shall not exist fracture and impact caused by bending, not allowed to loose, swing, when not meet the requirements, inch and inch replacement or maintenance.

　　铅板也叫铅皮指用金属铅轧制而成的板材，新铅为银白色，防护铅板时间长了会氧化为黑色，是防辐射物质中很重要的一种。由于它质量优秀，价格低廉，是中小型射线防护，墙体防护隔断的最佳板材。我们在使用时一定要对它进行维护和保养。

　　It is also called the lead sheet metal rolling and lead to a new lead, silver, lead door a long time will be oxidized to black, is a very important anti radiation. Because of its excellent quality and low price, it is the best board for middle and small size ray protection and wall protection partition. When we use it, we must maintain and maintain it.A
