WebBeta radiation, consisting of electrons or positrons, is stopped by a thin aluminum plate, but gamma radiation requires shielding by dense material such as lead or concrete. [1] A … Web29 de nov. de 2009 · Answer. Chris - Well, the reason that lead is a good choice is because it's a very dense substance, because dense substances can get in the way of the radiation and soak it up. And the denser something is the more atoms they have; in the case of things like x-rays and gamma rays, the more electrons there are to potentially interact with that ...
