虽然现在我们已经可以利用X射线来疾病了，但是我们还是要防备着X射线，因为X射线对人的损伤极大。记得有一部电视剧上演过这样的一幕，一位护士长怀孕了，上班的时候要进辐射室对病人进行，没有穿防护服，结果孩子受到损伤。这虽然是个电视剧，但也是有警示意义的，X射线一定要做好防护。怎么防护X射线呢？医用铅玻璃是个不错的选择。那么铅玻璃能挡多少X射线呢？
Although we can now use X rays to treat the disease, but we still have to guard against X rays, because X rays on human damage. Remember that there was a drama staged such a scene, a matron was pregnant, go to work when the radiation room to treat the patient, did not wear protective clothing, the result of child injury. Although this is a drama, but there are warning significance, X ray must do a good job of protection. How to protect X ray? Medical lead glass is a good choice. So lead glass can block how many X ray?
医用铅玻璃至少在120KV下是大于2mmpb的，也就是大于2mm铅当量，也有用厚度15mm厚的铅玻璃，那铅当量至少是3以上，足够防护住所有散射线
Medical lead glass is at least 120KV greater than 2mmpb, which is greater than 2mm lead equivalent, but also the thickness of 15mm thick lead glass, the lead equivalent of at least more than 3, enough to protect all scattering lines
铅玻璃的检测报告一般是10毫米厚的铅玻璃在120KV下检测的，可以达到2mmpb，但一般医院X光室和CT 室用的是15或者20厚的铅玻璃，所以可以防得所有的射线。
The test report of lead glass is generally 10 mm thick lead glass detection in 120KV, can reach 2mmpb, but the General Hospital of X light and CT room with 15 or 20 thick lead glass, so you can get all the rays.
