Yes, X-rays penetrate the skull. It takes something as dense as lead to completely block out x-rays.


Why does lead stops the penetration of gamma rays?

Materials period block gamma rays, but Lead is favored because it seems to do it best. Lead has a high atomic number, and therefore a large nucleus. The nucleus is what blocks the ray. Lead is also fairly inexpensive, so it's preferred.

Why are infrared waves easily blocked?

IR rays are just electromagnetic rays so the properties of infrared rays resemble to those of EM waves which can be easily blocked by thick materials. Lead is commonly used to block them.


Does lead block x rays?

Lead is a very dense substance and so can absorb most of the radiation which hits it, this means that less radiation is able to get to the part of your body which is not needing an x-ray. So, in short, lead is used to protect parts of the body from unnecessary exposure to radiation. This is good because radiation like x-rays can cause mutagens which can increase the rate of mutations in genes and DNA (sometimes causing Downs Syndrome etc.) WB
