射线防护门防护的要点是在射线源与人体之间放置一种能有效吸收射线的屏蔽材料。

　　射线防护门作为用金属铅轧制而成的板材，目前国内常见的厚度为1-20mm，常用规格为1000*2000MM，国内最好的机器可制作最宽1300MM，最长8000MM，多采用1#电解铅制作，市面上也有采用回收铅制作而成的。铅板规格范围在：厚度0.1~140mm;最大宽度1.5米;最大长度13米;特殊需要可协商加工。

选择医用气密门的器材需要注意事项：

　　针对医用气密门要求，正确选择性能符合要求的防护用品，绝不能选错或将就使用，特别是不能以过滤式呼吸防护器代替隔离式呼吸防护器。

　　医用气密门中的过滤式呼吸防护器将空气中有害物质予以过滤、净化，一般用于空气中有害物质浓度不很高，且空气中的含氧量不少于18%的场合。机械过滤式主要为防御各种粉尘、烟或雾等质点较大的有害物质的口罩，常称为防尘口罩。

　　另外在医用气密门之中时，要使用防护膏膜，在戴手套感到妨碍操作的情况下，常用防护皮肤污染，特别是有机化合物如各种溶剂、油漆和染料等，不但能经皮肤进入体内，且常引起职业性皮肤病。干酪素防护膏对此常可起到良好的防护作用。

　　Lead glass is mostly used in the radiology department of hospitals to protect against radiation. For hospitals, the advent of medical lead glass is particularly important. Therefore, in ordinary times, often to lead glass cleaning, because with ordinary glass is not the same, so in cleaning can not be cleaned according to the general method of cleaning glass. Following the lead glass manufacturers to introduce the lead glass cleaning matters needing attention:

　　铅玻璃的清洗一般都会使用强酸氧化剂洗液.强酸氧化剂洗液是用重铬酸甲和浓硫酸配成.K2Cr2O7在酸性溶液中,有很强的氧化能力,对玻璃仪器又及少有侵蚀作用.所以这种洗液在铅玻璃的清洁中使用比较广泛.这类洗液在使用时要切实注意不能溅到身上,以防"烧"破衣服和损伤皮肤.洗液倒入要洗的仪器中,应使仪器周壁全浸洗后稍停一会再倒回洗液瓶.第一次用少量水冲洗刚浸洗过的仪器后,废水不要倒在水池里和下水道里,长久会腐蚀水池和下水道,应倒在废液缸中,集中处理.

　　The cleaning lead glass will generally use strong oxidant lotion. Acid oxidant lotion is with potassium dichromate and concentrated sulfuric acid with.K2Cr2O7 in acidic solution, has strong oxidation ability, less corrosion of the glass instrument again. So this kind of lotion in the lead glass cleaning is widely used. This kind of the lotion is in use to pay attention not to splash on, to prevent the "burn" rags and damage the skin. Wash lotion in the instrument, the instrument should be Biquan week after a pause for a while and then fell back washing lotion bottle. For the first time with a small amount of water washing equipment just after washing wastewater, do not pour in the pool and in the sewers, water and sewer corrosion will for a long time, should be poured in the waste water tank, centralized treatment.

　　在清洗铅玻璃时还可能用到碱性洗液.碱性洗液用于洗涤有油污物的铅玻璃,从碱洗液中捞取铅玻璃时,要戴乳胶手套,以免烧伤皮肤.In the cleaning of lead glass may also use alkaline lotion. The alkaline lotion used for washing the lead glass oil dirt, from their lead glass alkali solution, to wear latex gloves, so as not to burn the skin.
