What materials protect against radiation?

Some beta particles can penetrate and burn the skin. γ GAMMA: To reduce typical gamma rays by a factor of a billion, thicknesses of shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead. Thick, dense shielding is necessary to protect against gamma rays.

What can absorb radioactive material?

Every plant absorbs radioactive material throughout its entire life. Two of the most common examples of naturally radioactive elements that plants absorb are potassium (as Jeffrey Semler answered), and carbon. All life on earth is carbon-based, and therefore contains some radioactive carbon.

What can absorb nuclear radiation?

For ionizing radiation that consists of alpha, beta and/or gamma rays, absorption depends on the mass per area of material in the direction of the radiation. Beta rays are more penetrating, and gamma rays are normally the most penetrating. To absorb neutrons you need material that has a lot of low mass nuclei.
