How can we absorb nuclear radiation with specific materials?

—Shielding--. The type of shielding depends entirely on the type of radiation: alpha, beta, gamma, or neutron. Alpha radiation can be stopped by a piece of paper, or a few inches of air, or the lead layer of skin on your body. Beta radiation is easily stopped. Even thick paper or thin metal will stop it. read more

Gamma radiation is much harder to stop. (The same is true of x-ray, but you asked about nuclear radiation.) In fact, you can only reduce the amount of radiation, you cannot stop all of it. The two things that make a good gamma shield are high atomic number and lots of mass. read more

That is a simple question with a simple answer. DIRT. Yes thats right dirt, cement, really any type of material can protect from radiation. The amount of material needed depends on the type of material we use. Theee feet of earth is sufficient to protect from radioactive fallout. read more
