The material that is most usually used to stop radiation is lead. Lead is composed of large atoms, being a heavy element with a high atomic number, and it is therefore quite opaque to radiation of all sorts. There are many other heavy elements which can stop radiation, however, lead is the most easily available. You can use platinum as well, but it is thousands of times more expensive than lead.

lead is a very dense material and can stop most radiation particles, although it is still dangerous as some gamma rays may get through.
Gamma rays can penetrate just about any type of matter. It takes meters of thick material to shield people from gamma rays.
No there is no material discovered which can stop the penetration of gamma radiations
Alpha is completely stopped by one sheet of paper or your outer skin layer.Beta needs several inches of material to stop it.Gamma requires tens of feet of concrete or lead to stop it.Neutrons require 10s of feet of borated concrete or a similar amount of water to stop them.
There are three primary types of nuclear radiation. Bricks will block both alpha particles and the more deeply penetrating beta particles. To stop gamma radiation, you would need several feet of brick. Lead is considered a better material for blocking high energy gamma rays.
Lead can stop gamma particles really fast because it is so dense. Gamma particles can also be reduced by water.
Nothing stops 'Gamma' rays, however you can block it with 1/2" of lead will prevent 1/2 of the radiation and then it will continue until it is and insignificant amount to record. Hope this was helpful.
Foam don't stop penetrating radiations (neutrons, beta, gamma lasers etc).
Nothing actually stops radiation, but lead slows it from spreading around.
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
Well It would most likely be gamma rays (gamma radiation) as it takes a wall of concrete several meters thick to stop them 2nd answer: Another form of radiation results in the emission of neutrinos, which are said to have no mass. As a result, they can whiz right through the earth, not to mention humans.
